4C1F879DAA1E450EFF53F8AEFBE38C5F.taxon	discussion	Dipsas multomaculata was described by Heinrich Boie’s elder brother Friedrich (1789 – 1870), in Latin and German (Boie 1827), and published in the year of Heinrich’s death. It has been suggested that Friedrich Boie attributed his description to H. Boie’s (1823 – 1825) “ Erpétologie de Java ” (Wallach et al. 2014). The latter work was never published and names proposed therein are considered unavailable for the purposes of nomenclature, according to the International Code of Zoological Nomenclature (ICZN 1999; ICZN 2012), hereafter referred to as “ the Code ”. However, F. Boie does not actually cite his brother’s unpublished work in his D. multomaculata species account. Rather he cites the Prussian-born Dutch pharmacist and botanist Caspar Georg Carl Reinwardt (1773 – 1854), yet no Reinwardt 1825 paper describing this taxon exists and it must be assumed that F. Boie was the person who introduced this binomen. Since Boie does attribute the taxon name to Reinwardt the degree of his involvement must therefore be determined. If Reinwardt just contributed the name with the specimen the citation would be Dipsas multomaculata F. Boie, 1827, but if he contributed both the name and a description of sorts, then the citation should be Dipsas multomaculata Reinwardt in F. Boie, 1827 (Aaron Bauer, pers. comm.). It would appear that the first scenario is correct (see also David & Vogel 1996: 21). Thus, the author citation is F. Boie, 1827 not Reinwardt in F. Boie, 1827 because F. Boie attributes the name to Reinwardt but not the description. Schlegel (1826: 238) also attributes the description of Dipsas multomaculata to Reinwardt when he writes „ Gen. DIPSAS Laur. Cuo, Esp. …… Col. multimaculatus (sic) Reinw. N. esp. … ” There is nothing in F. Boie’s account to suggest he referred to his brother’s unpublished manuscript for his description of D. multomaculata. However, the comparison of H. Boie´s manuscript part for “ Dipsas multimaculata ” and Friedrich Boie’s (1827) text on “ [Dipsas] multomaculata ”, which we regard as the original description, shows, that the latter is a verbatim copy of H. Boie´s manuscript with the exception of the different spelling of the species name and the reference to images which depict this species in earlier classical works. The primary types of this taxon have been stated to be unlocated (Nguyen et al. 2009; Uetz et al. 2019), as deposited in “ RMNH ” (Iskandar & Colijn 2002) or listed with incorrect quantity, syntype composition, and collectors (Wallach et al. 2014). They are actually present in the collection of the Naturalis Biodiversity Center (formerly Rijksmuseum van Natuurlijke Histoire, Leiden, Netherlands) and have been examined by one of the authors (FT). The enquiries in Leiden by FT and MOS revealed that H. Boie wrote his manuscript between 1823 and 1825, i. e., before his departure for Java. However, this also means that the material he and Macklot collected on Java between June 1826 and September 1827 (= RMNH 978 a + b) was not available to him when he wrote his manuscript. Thus, material used for the description must have already been in the Leiden collection. Therefore, only material that was previously collected by Kuhl and van Hasselt or Reinwardt would have been available to him and are very likely the specimens listed under RMNH 979. The material collected by H. Boie and Macklot (RMNH 978 a + b) could never have been part of the type series of D. multomaculata because F. Boie (1827) added nothing new to his brother’s text. It has to be noted that the order of the inventory numbers does not relate to the order of accession into the Leiden collection. A specimen (i. e., ZMB 2642) in the collection of the Museum für Naturkunde Berlin very likely also belonged to the original type series of D. multomaculata. According to a letter dated “ Leyden, 2 nd April 1825 ” (preserved in the Dept. of Historical Research of Berlin Museum, Acta Sign. ZM, Dr. Temminck, Leyden, 1818), Heinrich Boie wrote to Martin Hinrich Carl Lichtenstein (1780 – 1857, Director of the ZMB at that time) and offered him beside many other specimens from Java under list number “ 38 ” a specimen of “ Dipsas multimaculata ” for the price of 1 [Reichsthaler]. The same specimen appeared with the same number and same price in a list written by Lichtenstein documenting the arrival of the objects with the following title [translation by us]: „ List of the objects sent by Mr. Temminck from Leyden and arrived at the Museum [Berlin] on 9 March 1826 “. These hitherto unnoticed documents suggest that the specimen of D. multomaculata offered by H. Boie to the Berlin Museum in April 1825 must have belonged to the original type series and was probably collected by Kuhl and Van Hasselt and available to H. Boie when he worked on his manuscript. In addition, the scalation values of ZMB 2642 are within the variation given by H. Boie in his manuscript. The main reason why this specimen has not been considered as a type specimen so far is probably the fact that it is linked only to Coenraad Jacob Temminck (director of the Rijksmuseum van Natuurlijke Historie, Leiden and treasurer of the Dutch East India Company) who is cited as the donor in the Berlin Museum inventory catalogue and no one had previously evaluated the associated correspondence. Only RMNH 979 (a jar which contains six specimens) and the specimen later sent to the Zoologisches Museum Berlin were available for H. Boie’s manuscript. Of the six specimens under RMNH 979 only specimen b, d, e and f (all females) fit the scalation data of H. Boie (manuscript) and F. Boie (1827). Thus, in our opinion, the extant syntype series of D. multomaculata F. Boie 1827 consists of ZMB 2642 and four out of the six specimens listed under RMNH 979. The German naturalists Heinrich Boie (1794 – 1827) and Heinrich Christian Macklot (1799 – 1832) visited Java between December 1825 and September 1827. Esther Dondorp (Senior Collection Manager) and Karien Lahaise (Naturalis archivist) informed MOS that according to an unpublished manuscript by Marinus Hoogmoed “ H. Boie and Macklot arrived in Java on 6 June 1826. On December 28, 1826 they travelled to Krawang (Tjikao) [now Karawang, a town in West Java regency, Tjikao, now Ci Kao, is a watercourse south of Karawang]. H. Boie died on 4 September 1827 ”. Thus, the dates that both were working in Java together and collected these specimens may therefore be defined more accurately as 6 June 1826 to 4 September 1827. The two were in the employ of the Rijksmuseum voor Natuurlijke Historie (RMNH), as part of the Natuurkundige Commissie voor Nederlandsche Indie (Commission for Natural Sciences of the East Indies). In all documents (letters and manuscript) from H. Boie’s hand and publications based on H. Boie’s manuscript or written notifications by him (e. g., Schlegel 1826 and 1827) the spelling “ multimaculata ” is used exclusively. This also applies to the Leiden catalogue entries. Although this is to be taken as a clear expression of his will, we have to accept Friedrich Boie´s (1827) “ multomaculata ”, since the latter is responsible for the valid introduction of the name in the sense of the Code, Art. 50.1. This is also in line with the statements of David & Vogel (1996: 21). Numerous authors erroneously referred to this species as Dipsas multimaculatus or D. multimaculata (e. g., Duméril et al. 1854 b; Duméril et al. 1854 a; Theobald 1868 b; Boulenger 1890), and this misspelling of multomaculata as multimaculatus would continue when Boulenger (1896) placed the rear-fanged Asian cat snakes into the resurrected Dipsadomorphus, and even when they were transferred to Boiga by Smith (1923). In recent years most authors have been careful to use F. Boie’s correct spelling Boiga multomaculata. A number of obscure names have been proposed as synonyms of B. multomaculata. Wallach et al. (2014) suggested Coluber aldrovandi Merrem, 1820, to be a synonym of this taxon. However, reading Merrem´s description (1820: 125) it becomes obvious that it is not even a Boiga because some of the main characters noted by Merrem, e. g., keeled scales, head pointedly rounded, and the absence of a loreal scale are not characteristic for this genus. Also the values for ventrals (121) and subcaudals (49) of Merrem´s aldrovandi are far outside the range of B. multomaculata (see Table 1). Their action to declare Dipsas multomaculata a nomen protectum with priority over “ Coluber aldrovandi ” is therefore obsolete. Furthermore, Merrem´s taxon was not described in the combination with the genus name Coluber but with „ Natrix “. The name “ Natrix sturmii ” is based on an unpublished manuscript dated around 1825 by Johann Georg Wagler (1800 – 1832) (pers. comm. Van Wallach 17 March 2022) and is considered nomen ineditum because it was not been properly published according to the Code. Rudolf Emil Mell (1878 – 1970) was a German school-teacher and amateur naturalist collector working in China in the early 20 th Century. He returned to Germany in May 1921 and later proposed several subspecies of B. multomaculatus (Mell 1931), i. e., B. m. hainanensis, B. m. indica, and B. m. sikiangensis but these taxa have been considered synonyms of B. multomaculata since their inception (e. g., Pope 1935; Bourret 1936; Smith 1943). Whereas the syntypes of B. m. sikiangensis are known (i. e. ZMB 49427, 50879, 52642), no type material is known to exist for B. m. hainanensis or B. m. indica. The type localities of B. m. hainanensis (“ Hainan ”) and B. m. sikiangensis (“ Kwangtung (Hongkong) ”) are more precise than the one given for B. m. indica (“ continental India ”), especially since continental India at that time included Sikkim, Assam, Bengal (including today’s Bangladesh), Burma (Myanmar), and Pakistan. The various author’s copies of this publication that Mell distributed, including the one in the departmental herpetological library at Senckenberg Forschungsinstitut, contain a handwritten correction of B. m. hainanensis to “ sikiangensis Mell ”. Presumably, the author had a change of mind regarding his taxon name, but this has no nomenclatorial relevance. As far as we know, Mell never corrected it formally in a subsequent publication and the introduction of the name hainanensis must be regarded as valid published in the sense of the Code. At the time of writing Mell’s subspecies were not listed in the Reptile Database (Uetz et al. 2022).	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

4C1F879DAA1C4505FF53F9E0FC9788D0.taxon	discussion	In 1868 the description of Dipsas ochraceus was published by the German zoologist Albert Karl Ludwig Gotthilf Günther (1830 – 1914), then an assistant at the British Museum (Natural History) tasked with identifying 2,000 snake specimens in the collection. In his brief description of this species Günther (1868: 425), wrote: “ We have received this new snake from Mr. Theobald, who named it “, thereby attributing the authorship to William Theobald (1829 – 1908), a naturalist attached to the British Geological Survey of India. To complicate matters, Theobald (1868: 53) also published a description of Dipsas ochracea, in Latin and English, in the same year. The Reptile Database (Uetz et al. 2022) suggested that Theobald’s paper was published prior to Günther’s paper, pointing out that Günther referred to Theobald in his paper, but without providing a published source. The editors may have assumed that Günther had access to Theobald’s already published paper, thereby attributing authorship to Theobald, 1868. Wallach et al. (2014) were of the contrary opinion and proposed that the first description of D. ochraceus appeared in the Günther paper, and the authorship should therefore read “ Theobald in Günther, 1868 ”. This question over the priority of authorship can only be resolved by determining which of these two papers was published first. Günther published his description in the Annals and Magazine of Natural History, series 4, volume 1, number 6, which was published on 1 st June 1868 (Evenhuis 2003; F. Tillack unpubl. obs.). Theobald published his account in the Journal of the Linnean Society of London (Zoology), volume 10, number 41. The year of publication is often given as 1868 (Smith 1943; Wallach et al. 2014; Uetz et al. 2022) but the situation is somewhat unclear. Following its title, Theobald’s paper reads “ By W. Theobald. Jun., Geological Survey of India. Communicated by G. Busk, Esq., Sec. L. S. [Read November 7, 1867.] ”. The paper was therefore presented orally at a meeting of the Linnean Society of London in late 1867, but that does not constitute “ published ” according to the Code. According to the title page of the journal, volume 10 was not published until 1870 (Theobald 1868 b) which would seem to give priority to Günther’s 1868 paper, but this was not the actual date of publication of Theobald’s paper. According to the archives of the Linnean Society of London “ pages 4 – 67 of Volume 10 of the Journal of the Linnean Society of London (Zoology) were issued on 30 May 1868. The reason the front page is dated 1870 (May 20 th) is because that is when the title and contents page were finished, ready for the rest of the journal to be bound ” (Vida Milovanovic, Linnean Society of London, pers. comm.; F. Tillack unpubl. obs.). Therefore, Theobald’s description takes precedence over Günther’s paper, by two days, and the correct citation should be Theobald (1868). Amongst the distinguishing characteristics of D. ochraceus, Günther documented 19 dorsal scale rows, 239 – 242 ventral scales, and 100 subcaudal scales. His description was based on the two specimens obtained from Theobald, the largest of which he measured at 44 inches (1.12 m), and both of which, he reports, were collected at Pegu (now Bago, 17 ° 19 ′ N, 96 ° 28 E), central Myanmar. Theobald’s description differs in a number of respects from that of Günther. He states that he personally collected the first specimen at Rangoon (now Yangon, 16 ° 48 ′ N, 96 ° 09 E), and that his second specimen was collected by Colonel David Browne, at Maulmain (= Moulmein, now Mawlamyine, 16 ° 29 ′ N, 97 ° 38 ′ E) in the Tenasserim Region (now Tanintharyi Region, southern Myanmar). He also measured the first specimen at fully nine inches (229 mm) shorter than the measurement provided by Günther, and finally, Theobald reports that both specimens exhibited dorsal scale counts of 19 on the neck, 17 on the body, and 15 near the tail, in contrast to the dorsal count of 19 provided by Günther, presumably taken at midbody, and a count supported by Boulenger (1896) and Stimson (see later). Given the reported differences in localities, collectors and description, there is no doubt that the two authors described their species using different specimens. However, regarding the reported differences in the number of dorsal scale rows at midbody, it has to be noted that many Boiga have a rather chaotic dorsal scale row reduction which can go up and down more than three times within a range of only 10 corresponding ventral scales “ at midbody ”. Furthermore, the measured midbody can be different from the midbody position determined by counting half the number of ventrals.	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

4C1F879DAA1C4505FF53F9E0FC9788D0.taxon	discussion	As far as we are aware, the two types of D. ochracea Theobald are unlocated. They were not listed by Theobald (1868 a), nor in Sclater (1891) or in Das et al. (1998). Some time ago one of us (AD) checked the collection in ZSI, Kolkata, but found no specimens marked as type for Theobald´s ochracea and none of the specimens examined by him agreed with Theobald’s description or locality. During the late 19 th Century the British Museum (Natural History) received five further specimens of D. ochracea from Myanmar, i. e., two specimens (BMNH 74.4.29.1193 – 1194) from Myanmar, reportedly collected by the British army officer and naturalist Richard Henry Beddome (1830 – 1911), and three specimens (BMNH 89.2.25.37 – 39) from Bhamo, in Kachin State, northern Myanmar, collected by the Italian naturalist Leonardo Fea (1852 – 1903). Ferdinand Stoliczka (1838 – 1874) was a Austrian paleontologist and naturalist who worked in India during the mid 19 th Century, but died of altitude sickness during a Himalayan expedition. He exhibited a considerable interest in snakes and in 1870 he reported on five specimens from the Andaman Islands which he attributed to the taxon Dipsas hexagonotus Blyth, 1855 (Stoliczka 1870). In the late 19 th Century the Anglo-Belgian zoologist George Albert Boulenger (1858 – 1937), was Günther’s assistant at the British Museum (Natural History) and the person now tasked with the continued cataloguing of the herpetological collection. In 1890 he resurrected the genus Dipsadomorphus Fitzinger, 1843, for the African, Asian, and Australasian cat snakes previously included in the genus Dipsas (Boulenger 1890; Boulenger 1896) and he synonymised Günther’s Dipsas ochraceus with Blyth’s older Dipsadomorphus hexagonatus. Adopting this new classification, the British physician and herpetologist Major Frank Wall (1868 – 1950) examined Blyth’s Dipsas hexagonotus type specimen (ZSIK 8048), from “ Cherrapunji, Khasi Hills, Assam ” [= Sohra, East Khasi Hills district, Meghalaya state, India] and reidentified it as a juvenile Dipsadomorphus cyaneus, now Boiga cyanea (Duméril, Bibron and Duméril, 1854) (Wall 1909). He also examined the four adult specimens in Stoliczka’s Andaman Dipsas hexagonotus, which exhibited a dorsal scale count of 21, and included them in the syntype series of his new species Dispadomorphus andamanensis, now Boiga andamanensis. The remaining specimen from Stoliczka’s Andaman series reportedly possessed 19 dorsal scale rows, but Wall commented that its description was imperfect and the specimen itself appeared to be lost. Further, Wall (1909) recognized that the mainland D. hexagonotus material he had available appeared to represent two different taxa. Five of the BMNH specimens (BMNH 1946.1.2.60 – 61, 89.2.25.37 – 39) from Myanmar, and a further nine specimens he had personally collected, all possessed 19 dorsal scale rows, 221 – 245 ventrals and 89 – 107 subcaudals which complied with the description of D. hexagonotus, and to which he applied that name, citing Stoliczka’s missing Andaman specimen as the holotype. It is curious that he sought to conserve the name “ hexagonotus ”, as Dipsadomorphus hexagonotus, by transferring it from Blyth’s holotype, now known to be a juvenile D. cyaneus, to Stoliczka’s missing and incompletely described juvenile. Fortunately, this move is illegal according to the Code (Smith 1943), meaning the name is unavailable and D. hexagonotus remains synonymized with D. cyaneus. The Myanmar population with 19 dorsal scale rows should therefore be known as D. ochracea. Two further Myanmar specimens available to Wall (BMNH 74.4.19.1193 – 94) exhibited a dorsal count of 21, which was more akin to that obtained from Himalayan specimens. These two specimens were reportedly collected in Myanmar, well within the range of those specimens attributed by Wall to D. hexagonotus. However, they were collected by Beddome, and Wall had already voiced criticism regarding the accuracy of Beddome’s record keeping. In the case of these two specimens he suggested that they could have easily come from “ the hills to the west or north of Burma, the fauna of which closely agrees with that of the Eastern Himalayas ”. Furthermore, Smith (1943) stated that Beddome never visited Burma, and therefore the long-accepted collection locality for these two specimens must be treated as extremely suspect. Similarly, a specimen of “ Boiga ochracea ” donated by Beddome to the Museum of Comparative Zoology (i. e., MCZ R- 3886) is said to come from “ Madras ” [Chennai] at the southeast coast on India. However, the given locality is far outside the distribution limits of this group and our reexamination revealed that this specimen is a B. stoliczkae which very likely originated from the eastern Himalayas. Wall (1909) also examined 39 specimens from the Darjeeling area of West Bengal, India, which exhibited 21 dorsal scale rows, 218 – 252 ventrals, and 100 – 119 subcaudals. To this series he added a further three Darjeeling specimens in the British Museum (Natural History). Two of these (BMNH 72.4.17.119, 72.4.17.386) were collected by the British naturalist and physician Thomas Caverhill Jerdon (1811 – 1872), while the third specimen (BMNH 94.12.31.55) was collected by the British geologist and naturalist William Thomas Blanford (1832 – 1905). Finding this Eastern Himalayan taxon without a name, Wall (1909) proposed Dipsadomorphus stoliczkae, “ the first reference of it having been made by Stoliczka ”. Annandale (1909) discussed Wall’s (1909) paper on the forms of Dipsadomorphus, and criticizes the, in his opinion, difficult delimitation of the species introduced by Wall, particular with regard to Boiga ceylonensis, but also to other species of this genus, and considered Wall’s new species merely as forms of one species, i. e., of B. ceylonensis. Cope (1860) resurrected the name Boiga Fitzinger, 1826 and designated Coluber irregularis as type species. In 1902 the Norwegian-American zoologist Leonard Hess Stejneger (1851 – 1943) described a new species of rear-fanged snake from Taiwan (then Formosa), and in so doing also resurrected the genus Boiga Fitzinger, 1826 from obscurity as a senior synonym for Dipsadomorphus, the generic name it would replace for the remainder of the 20 th Century. The two taxa under discussion here would therefore become Boiga ochracea (Theobald, 1868), with 19 dorsal scale rows, from NE India south and east of the Brahmaputra valley across Bangladesh to Myanmar, and B. stoliczkae (Wall, 1909), with 21 dorsal scale rows, from the Eastern Himalayas, but including Beddome’s two “ Burmese ” specimens. From all that we now know and have examined, B. ochracea does not occur on the Andaman or Nicobar Islands, that material being referred to Boiga andamanensis (Wall, 1909). This assumption is also confirmed by the recent studies of Chandramouli (2022: 321), who removes B. ochracea from the list of snake species occurring on the Andaman Islands. It has to be noted that B. andamanensis usually has 21 midbody DSR, rarely 19, but in preservation the coloration looks like “ ochracea ”, particular in the red color morph, a possible reason for the confusion. The next author to take a look at this group of snakes was the British physician and herpetologist Malcolm Arthur Smith (1875 – 1958). In 1941 he used for the first time the combination Boiga ochracea walli (as a nomen nudum) and applied this name to populations from the Andaman and Nicobar islands, and Burma. A few years later Smith (1943) synonymized B. stoliczkae with B. ochracea, stating: “ The name hexagonatus must become a synonym of cyanea, and the next one available is Günther’s ochracea. The type has 21 scale rows and is therefore the Himalayan form, and the locality (Pegu) from which it is said to have come is in no doubt an error. Beddome, from whom the specimen came, was never in Burma, and his localities have been shown to be incorrect on many occasions. ” Smith (1943) defined his eastern Himalayan B. ochracea ochracea as exhibiting 21 - 21 - 17 dorsal rows, 223 – 252 ventrals, and 100 – 119 subcaudals, and described the populations of B. ochracea from “ Burma, south of lat. 25 °; Tenasserim; the Andaman and Nicobar Islands. ”, with 19 - 19 - 15 dorsal rows, 221 – 246 ventrals, and 89 – 107 subcaudals, as a new subspecies, formally named B. ochracea walli. On the BMNH ledger and on the jar labels, the BMNH specimens collected by Leonardo Fea at Bhamo, Myanmar, (i. e., BMNH 89.3.25.37 – 39) are declared as syntypes. However, this does not constitute a type selection according to the Code and is therefore not a valid syntype designation because it is not following the principles of typification. Smith (1943) did not cite any type material from his B. ochracea walli in its original description. Therefore, all specimens available to Smith at the time of the description of B. ochracea walli constitute the syntypes, not just the three specimens subsequently labeled as “ syntypes ” in the BMNH collection. The list of potential syntypes of Smith’s B. ochracea walli obviously includes specimens present at BMNH at the time but it is known that Smith travelled in South and Southeast Asia and visited all the main collections there in the preparation of his “ Fauna of British India ” series, the third, Serpentes, volume of which was ready to go to print in 1938 (delayed until 1943 due to WWII). He examined material from the collections in Bombay, Calcutta, Paris (Smith 1943: v – vi), Vienna (Smith 1928) and Berlin (pers. data FT, he was in contact with Mell and arranged specimen loans with ZMB), and also loans from different US museums and from Leiden and Colombo (Smith 1943). So it cannot be ruled out that specimens from these collections are also putative syntypes of Smith´s B. o. walli. Wallach et al. (2014) treated walli as full species and mentioned that this taxon is based on a single name-bearing type specimen, but they provided no inventory number for that specimen. According to Art. 72.4.1 of the Code (“ The type series of a nominal speciesgroup taxon consists of all the specimens included by the author in the new nominal taxon (whether directly or by bibliographic reference) … ”, we suggest that in the case of B. ochracea walli at least the following specimens belong to the original syntype series: BMNH 1946.1.2.60 – 61 from Pegu (at the same time syntypes of Dipsas ochraceus Günther), BMNH 89.3.25.37 – 39 from Bhamo, and specimens from the Andamans and Nicobars, at least from the BMNH collection which were available to Smith. Smith appears to have made a number of errors that had a considerably impact on the nomenclature and proposed distributions of these taxa. 1) It was Theobald, not Günther, who first described ochracea in 1868. 2) The ochracea type specimens (plural not singular) were recorded by Günther, as having come from Pegu (= Bago), but Theobald’s syntypes were collected from Rangoon (= Yangon) and Maulmain (= Mawlamyine). Regardless of any confusion over precise localities, the two syntypes described by Theobald and the two other described by Günther were collected in southern Myanmar, not the eastern Himalayas or northern Myanmar. 3) Günther recorded the dorsal scale rows of these two specimens as 19, while Theobald reports 19 - 17 - 15 rows, but neither author reported a count of 21 for these specimens. 4) Beddome was responsible for collecting the two specimens reported as from “ Burma ”, not the two specimens from Pegu, and it is this locality that is now doubted by most authors, and it was these two specimens that exhibited 21 dorsal scale rows at midbody. Not all authors accepted Smith’s synonymy of stoliczkae with B. ochracea, i. e., Kramer (1977) who reported that Andrew Stimson (BMNH) had checked the syntypes of Günther´s D ochraceus (BMNH 1946.1.2.60 – 61) and confirmed their dorsal scale counts as 19, and that they were collected in southern Myanmar and therefore he did not synonymise stoliczkae with ochracea, but rather recognized it as the eastern Himalayan-northern Burmese subspecies B. ochracea stoliczkae. It has to be noted here that all material examined by Kramer and determined by himself as B. o. stoliczkae was misidentified. Our re-examination (by FT) revealed that FMNH 131957 is Boiga multifasciata and FMNH 152584 is Boiga trigonata. Gruber in Schleich & Kästle (2002) recognized all three subspecies: B. o. ochracea from Darjeeling, Sikkim, Assam, Bhutan and Bangladesh; B. o. stoliczkae from Nepal, and B. o. walli as characterized by Smith (1943) from southern Myanmar and the Andaman and Nicobar Islands, but they did not provide any characteristics to distinguish between the three taxa. Therefore, there appears to be a great deal of confusion over the nomenclature and distribution of the various populations of B. ochracea, largely caused by Smith’s misinterpretation of the data and some recent authors (e. g., Das 2010; Wallach et al. 2014) largely followed Smith’s (1943) erroneous concept of this group. As a consequence of what is stated above, we consider Boiga walli to be a synonym of B. ochracea, and we elevate B. stoliczkae again to species level, distinct from B. ochracea. To summarize the current situation, Boiga ochracea should be the taxon with 19 - 19 - 15 or 13 dorsal scale rows, cream to beige color without any pattern, from NE India south and east of the Brahmaputra valley across Bangladesh to Myanmar. Boiga multomaculata should be the taxon with 19 - 19 - 15 or 13 dorsal scale rows and a bold pattern of ocellated dark blotches, definitely known from Myanmar and southern China across Thailand, Laos, Vietnam, and the Sunda Archipelago. Boiga stoliczkae should be the taxon with 19 or 21 - 21 - 15 or 17 dorsal rows that has been reported from Nepal, northeast India north and west of the Brahmaputra valley, and Bhutan. In this work, we evaluate the genetic variation in the populations related to Boiga multomaculata, B. ochracea, and B. stoliczkae, respectively, based on the mtDNA markers 16 S, ND 4, and CYTB as well as the nuclear marker c-mos. We also analyze the variation in external morphology of these three taxa. Finally, we designate lectotypes for Boiga multomaculata, B. ochracea walli, and B. stoliczkae, and a neotype for Boiga ochracea respectively, and provide redescriptions of the primary types from these taxa.	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

4C1F879DAA0C451BFF53FC32FE868D8B.taxon	distribution	Geographic distribution. As currently known, B. m. multomaculata is distributed across Thailand south of 17 ° N latitude, central and southern Laos, Cambodia, Vietnam, southern China (including Hainan) and on the Indonesian islands of Java, Bali, and probably Sumatra (Zhao & Adler 1993; David & Vogel 1996; Nguyen et al. 2009; Das 2010; Chan-ard et al. 2015). There are a number of incorrect listings of this taxon. An erroneous Singapore record goes back to Cantor and led to B. multomaculata being listed for West Malaysia, too. The absence of B. multomaculata on Malayan Peninsula was already clarified by Smith (1930: 63 – 64). For Sulawesi, Borneo, Singapore (West Malaysia) no reliable records are available or no vouchers are preserved in any collection. However, various authors still listed some of these implausible localities in very recent literature and in databases. David & Vogel (1996) report the presence of B. multomaculata on Sumatra but there are no references that provide a reliable record for the taxon from this island. Most probably the inclusion of Sumatra is based on a misinterpretation of a paper from Franz Werner (1900) about a collection from Sumatra purchased by Schneider. This paper includes a table with species that occur on Sumatra set against adjacent regions / islands. In this table B. multomaculata is listed, but not for Sumatra! It is possible someone reading the title of Werner’s paper and seeing B. multomaculata listed, came to the incorrect conclusion that it was present.	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

4C1F879DAA054511FF53FDD8FC638DDE.taxon	diagnosis	Diagnosis. A subspecies of Boiga multomaculata that differs from the other two subspecies (i. e., B. m. multomaculata and B. m. ochracea) by mean pairwise genetic distances of 3.3 – 5.8 % (ND 4) and 3.7 – 6.5 % (CYTB), respectively. It further differs from B. m. multomaculata by having on average more ventral scales in both sexes (males 227.7 ± 5.19, females 228.8 ± 1.71 in B. m. septentrionalis versus males 214.4 ± 8.06, females 217.1 ± 9.50 in B. m. multomaculata), by having on average more subcaudal scales in both sexes (males 99.1 ± 5.82, females 97.3 ± 2.06 in B. m. septentrionalis versus males 94.5 ± 5.33, females 89.8 ± 4.13 in B. m. multomaculata), and by having both blotched and patternless individuals (versus only blotched specimens in Boiga m. multomaculata). It further differs from B. m. ochracea by having on average fewer ventral scales in females (228.8 ± 1.71 in B. m. septentrionalis versus 238.9 ± 6.30 in B. m. ochracea).	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

Dentition. Maxillary bone with 11 / 11 prediastemal teeth, followed by a distinct diastema which is 40 % longer than the socket of the last prediastemal tooth and followed by two distinctly enlarged, grooved and posteriorly bent postdiastemal teeth. Prediastemal teeth slightly decrease in size posteriorly, the anterior three distinctly posteriorly hooked, the following with less pronounced curvature. On the left side, prediastemal teeth number two, four, six, eight and ten, and first postdiastemal loose. On the right side, prediastemal teeth one, three, five, seven and nine, and first postdiastemal tooth loose. Medial to each maxillary tooth is a single replacement tooth at different growth stages. Palatine bone with 6 / 6 posteriorly strongly curved teeth, shorter that the prediastemal teeth and slightly decreasing in size posteriorly. Tooth three six loose on left side. Teeth two, four and six loose on the right side. Lateral to each palatine tooth is a single replacement tooth at different growth stages. Pterygoid bone with 11 / 12 posteriorly curved teeth, shorter than the palatine tooth, gradually decreasing in size posteriorly. Teeth two, five, seven and 10 loose on left side. Teeth one, three, five, 10 and 12 loose on right side. The posterior 63 % of the pterygoid bone are without teeth. Mandibular bone with 18 / 17 posteriorly curved teeth, shorter than maxillary teeth, gradually decreasing in size posteriorly. Medial to each mandibular tooth is a single replacement tooth in different growth stages. Teeth one, three, five, seven, nine, 11, 13 and 15 loose on left and right side. Tooth 17 missing on right side. Coloration after about 13 years preservation in 70 % ethanol was recorded as follows: Dorsal ground color Smoke Gray (Color 266) with Natal Brown (49) mottling on scales and with 62 Sepia (286) blotches that have a paler (Grayish Olive 274 suffused with Smoke Gray 266) center and a white to Pale Buff (1) border. Dorsal scale reduction formula. 4 + 5 (10) – 9 (150) 2 + 3 (158) (5) 21 ------------ 19 ----------- 17 ------------- 115 (226). 4 + 5 (10) – 9 (152) 3 + 4 (159) Variation. Paratypes agree well with the holotype in general appearance, morphometrics and scalation (Table 1). Most paratypes are blotched as is the holotype. An exception is SMF 106288 (formerly CAS 239222) that has no blotches but exhibits 58 indistinct transverse dark bars composed of dark edges of adjacent dorsal scales. Variation in dentition. Ten to 12 prediastemal teeth followed by a distinct diastema and two enlarged grooved postdiastemal teeth; five to six palatine, seven to 12 pterygoid, and 16 to 19 dental teeth. Variation in live coloration and pattern. Two color morphs, blotched and unicolored are known. The blotched morph resembles the color and pattern of brownish individuals of the nominate subspecies. The unicolored morph (Fig. 16) resembles the unpatterned morph of B. m. ochracea. An intermediate color variation is known from Nagaland, NE India (WII-AD 856), which resembles the ground coloration of the unicolored morph but shows a Raw Umber (280) postocular stripe, faint dark dorsal had pattern similar to that of the nominate subspecies and an irregular strippled Raw Umber (280) pattern forming broken bands along dorsal body and tail.	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

4C1F879DAA054511FF53FDD8FC638DDE.taxon	etymology	Etymology. The species epithet is formed from the Latin words septentrio (= “ north ”) and the suffix - alis (to form an adjective) and refers to the geographic distribution of this taxon. Boiga m. septentrionalis has the most northern distribution of the subspecies of B. multomaculata. Natural History. The holotype of B. m. septentrionalis was collected at 19: 30 hrs. in bamboo, about 2 m above ground. The paratypes were all collected at night when Boiga is active. At the time of capture, the air temperature was 26.1 – 28.2 ° C and the relative air humidity was recorded as 81 – 96 %.	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).

4C1F879DAA02452DFF53FB31FD258D81.taxon	materials_examined	Type material. Wall (1909: 155) mentioned that he has examined 39 specimens of this new species from the “ neighbourhood of Darjiling ” (Darjeeling, West Bengal state, India), which is characterised by having 21 [midbody] scale rows, 218 – 252 ventrals and 100 – 119 subcaudals. He did not specify particular specimens by inventory number and with the exception of the British Museum (Natural History) he does not mention any other collection in which the type material could be deposited. However, it is documented through his publications (e. g., Wall 1909; 1921) that he examined for his studies not only his own material but beside specimens from the British Museum also material from various collections in India (e. g., BNHS Mumbai, ZSI Kolkata, and St. Joseph’s College in Darjeeling). After his retirement in 1925 he presented parts his own collection, including type specimens, to the British Museum (Natural History) in London (Smith 1951). Based on information provided by Andrew Stimson, Curator of Herpetology at the BMNH, Kramer (1977: 735) was the first to mention inventory numbers for the type material of D. stoliczkae and regarded a series of eight specimens, i. e., BMNH 72.4.17.119, 72.4.17.386, BMNH 74.4.1193 – 94, BMNH 94.12.31.55, and 1909.3.13 – 15 as syntypes. The two specimens mentioned by Wall (1909) and already considered by him as doubtful with respect to the locality “ Burma “, refer to BMNH 74.4.1193 – 1194 and were presented by R. H. Beddome (see also Introduction, and Wall 1908: 714 footnote; Wall 1910: 791 footnote). All aforementioned specimens are also marked as syntypes in the inventory ledger of the herpetological collection of the BMNH, now NHM London. However, some other specimens must also be regarded as part of the original series of D. stoliczkae, since they came from “ Darjeeling “ and where part of Wall´s donation to the collection in London, registered in 1930, viz. BMNH 1930.5.8.648 – 649, 1930.5.8.650, and 1930.5.5.651. Thus, the material in the NHM London alone represents only a portion of the original specimens examined by Wall. Therefore, we also consider specimens in Indian collections as potential type material of D. stoliczkae that could have been available to Wall if the temporal context, locality, and morphological characters are consistent with those in his original description. Putative syntypes that fit Wall’s diagnosis, were collected in the “ neighbourhood of Darjiling ”, and which were already in the respective collection prior to 1909 include BNHS 1772 from “ Tindharia ” (~ 20 km southeast of Darjeeling), and ZSIK 7869, 7873, 7878, 8476 and 11367 all from “ Darjeeling ”. In agreement with Art. 74.7 of the Code, we here designate BMNH 94.12.31.55 (Figs. 17 and 18) as lectotype of Dipsadomorphus stoliczkae Wall, 1909 to introduce a standard of application for the species group name stoliczkae Wall by a single name-bearer.

Boiga stoliczkae is mostly semiarboreal, crepuscular and nocturnal. It is known to inhabit open forest types, agricultural land, human habitations, and gardens, where it is found on low vegetation, bushes and walls. The altitudinal distribution ranges from lowlands, mid hills and submontane regions, from around 85 m up to 2000 m a. s. l. It is reported to feed on birds, their eggs, lizards, snakes (Trachischium fuscum), and small rodents (our observations; Shaw et al. 1941; Greene 1989; Tillack 1999; Gruber 2002; Jha & Thapa K. 2002; Shah & Tiwari 2004; Nepali & Singh 2020; Pradhan 2021).	en	Köhler, Gunther, Charunrochana, Panupong Thammachoti, Mogk, Linda, Than, Ni Lar, Kurniawan, Nia, Kadafi, Ahmad Muammar, Das, Abhijit, Tillack, Frank, O’Shea, Mark (2023): A taxonomic revision of Boiga multomaculata (Boie, 1827) and B. ochracea (Theobald, 1868), with the description of a new subspecies (Squamata, Serpentes, Colubridae).
