357987BDFF9FFF8468B583F1FA8CFC7F.taxon	discussion	Schaus (1896) described this genus for his new species, C. oweni Schaus, 1896. Subsequently, C. oweni was made a synonym of C. phalaenoides (Drury, 1773), but below we demonstrate that C. oweni is a valid species.	en	Cock, Matthew J.

357987BDFF9FFF8168B582D9FD48FD7B.taxon	description	Rothschild (1909) described and illustrated C. sordidior based on four males from Trinidad (Caparo) and Brazil (Fonte Boa, Amazonas) (Fig. 1 E). In Rothschild (1910), he listed the types as three males from Trinidad and one from Fonte Boa. Travassos (1957) incorrectly states that Rothschild (1910) restricted the distribution to Fonte Boa. Travassos also made C. sordidior a synonym of C. phalaenoides, and this was followed by Watson and Goodger (1986). However, Vincent and Laguerre (2013) reinstated C. sordidior as a valid species, noting that the two species have distinct DNA barcodes in Central America (C. phalaenoides, BOLD: AAA 1439) and French Guiana (C. sordidior, BOLD: AAA 7016). At that time, the treatment of C. oweni as a synonym of C. phalaenoides was not considered. Given that Rothschild (1909) described this species from two widely separated localities, a lectotype needs to be fixed, to avoid any possible ambiguity — there is at least one undescribed species of this group from southern Brazil (M. Laguerre unpublished). Rothschild (1909) listed the Trinidad type material first, and there are three syntypes from Trinidad and only one from the Amazon (Rothschild 1910), so it would be appropriate to select one of the Trinidad specimens as lectotype. Furthermore, Rothschild (1909, Plate 7.5) illustrated a male syntype from Trinidad (Fig. 1 E), which is currently labelled as ‘ type’ in NHMUK (Fig. 1 F). Accordingly, we designate this specimen the lectotype. Further to the conclusions of Vincent and Laguerre (2013) based on DNA barcodes, there are slight differences in the male genitalia of C. phalaenoides and C. sordidior (Fig. 2): the uncus in C. phalaenoides is longer and more dilated basally; the translucent sacculus on the valve is slightly shorter than the valve in C. phalaenoides, but about half the length of the valve in C. sordidior; and the saccus is pointed anteriorly in C. phalaenoides and more rounded in C. sordidior (Fig. 2). In our consideration of these two species, it became apparent that as described by Rothschild (1909), the males are more easily distinguished than the females (Figs. 1, 3). Thus, Rothschild (1909) (implicitly) compared (male) C. sordidior with (male and female) C. phalaenoides: ‘ This species has the forewing much less truncate, more pointed, and the hindwing rounder, less angulated; the pectus is orange, not lemon-yellow; the thorax olive-green, not bright olive-yellow; abdomen black-brown, not yellow, last segment olive-yellow. The forewing has the olive-green areas much darker and the hyaline areas much reduced by increased olive-green markings; the inner marginal area yellowish green, not yellow. Hindwing olive-grey, not yellow. ’ We believe it is likely that Rothschild (1909, 1910) only recognised the male of C. sordidior, and treated the female as C. phalaenoides. We reconsidered the identity of C. oweni in light of these findings. We have seen no specimens of C. phalaenoides from east of the Andes in the continent of South America. The type locality of C. oweni is Aroa, northern Venezuela, and this species is therefore more likely to be the same as the species described from Trinidad (sordidior) than the species described from Belize (phalaenoides). In order to clarify the identity of C. oweni, we examined an image of the only putative paralectotype male from Schaus’ collection from the lectotype locality, Aroa, Venezuela in USNM (P. Goldstein, pers. comm. 2019) (Fig. 1 C), and found it resembled C. sordidior rather than C. phalaenoides. Although we did not dissect this male, we did dissect a male from Rancho Grande, Parque National Henri Pittier, Aragua State, Venezuela, about 130 km to the east, and confirmed it to be C. sordidior. We therefore conclude that C. oweni stat. rev. is a valid species, distinct from C. phalaenoides, and C. sordidior Rothschild, 1909 is a syn. nov. of C. oweni Schaus, 1896. Hence, the type species of Castrica is unambiguously C. oweni rather than a synonym of C. phalaenoides. Furthermore, it is now clear that Travassos’ (1957) suggestion above that the type of C. oweni could be taken as the neotype of C. phalaenoides is not acceptable. Since at this time only the one species of Castrica is recognised from Central America, including from the Belize type locality, its identity as C. phalaenoides is unambiguous and there is no urgent need to designate a neotype.	en	Cock, Matthew J.

357987BDFF9AFF8D68B58777FD4CFC6E.taxon	description	Figs. 4, 5. BIN: BOLD: AAH 7679 (dx. doi. org / 10.5883 / BOLD: AAH 7679) Möschler (1883) described the genus Pryteria for his new species P. costata Möschler, 1883. The genus then fell out of use until Watson (1975) used it for a group of eight species (and three additional subspecies) resembling P. costata, which had mostly been including in the catch-all genus Automolis. Vincent and Laguerre (2014) list nine species and three additional subspecies (Table 1). This is the same as Watson’s (1975) treatment, except that Watson treated P. nigroapicalis as a form of P. costata. We investigated what name to apply to the species in Trinidad that appeared to be P. alboatra, and realised that most of the named species of Pryteria are synonyms of a single variable, sexually dimorphic species as follows. It has long been suspected that this group of species now brought together in Pryteria (Fig. 4), contains multiple synonyms. Thus, Seitz (1920 – 1925) treated the male taxa borussica, alboatra, hamifera and apicata as forms of P. unifasciata, and Rothschild (1935) agreed this was likely to prove correct when more material was available. In French Guiana, several forms can be collected together (specimens resembling P. costata, P. nigroapicalis, P. semicostata, P. alboatra, P. unifascia, P. hamifera and P. apicata in MNHN, plus un-named forms in Fig. 5). In Trinidad, the male form normally found is P. alboatra, but one male is close to, but not the same as P. unifascia (Fig. 5 D), while females resemble P. semicostalis. Dissections revealed the male genitalia of these two male forms from Trinidad to be identical. Published figures (Watson 1971) and new images (P. Goldstein pers. comm. 2019) of the male type dissections of P. hamifera and P. apicata were compared and are also identical, as are the genitalia of the male type of P. unifascia in OUNMH and a male paralectotype of P. alboatra in NHMUK. The types of other species have not been dissected. The evidence from barcodes is also revealing; a single species level cluster (BIN BOLD: AAH 7679; dx. doi. org / 10.5883 / BOLD: AAH 7679) of ten samples identified as four species encompasses material identified based on habitus as follows: P. alboatra, French Guiana (x 3), Peru (Cuzco); P. semicostalis, French Guiana (x 3), Peru (Huanuco); P. nigroapicalis, French Guiana; P. borussica (a subspecies of alboatra in Vincent and Laguerre (2014 )), Paraguay. The p distance to the nearest neighbour BIN BOLD: AAF 2409 (Cratoplastis sp.) is 4.33 %. Thus, we have good evidence based on genitalia or DNA barcodes that six of the nine taxa of Pryteria listed by Vincent and Laguerre (2014) are synonyms of a single, widespread, variable species, found from Paraguay, through the Amazon Basin, the Guianas and Trinidad. Males of Pryteria (BOLD: AAH 7679) are cream-coloured with dark markings: on the forewing, the apical dark patch may be present or absent; the dark bar along the dorsum may be entire, interrupted or split in the basal third, or stop short of the tornus; the dark bar across the wing may be absent, represented by markings on the costa and at tornus, almost complete, narrow or broad; on the hindwing, the dark shading on dorsum is variable, and the shading on the margin may be absent, present near the tornus, or present for the entire margin. Females of Pryteria (BOLD: AAH 7679) are dark with cream markings: on the forewing, the subapical bar may be present or absent, or represented by a cream patch on costa only; the apical area distal to this bar may be cream or dark; the basal hindwings are variable in the extent of cream colouring. Of the remaining species of Pryteria, P. costata is the oldest name in the genus as well as the type species; it was described and illustrated from a female specimen from Suriname that has not been located (Vincent and Laguerre 2014). It closely resembles P. semicostalis, but the white discal band of the dorsal forewing is slightly sinuous and there is no pale costal area on the dorsal hindwing (Fig. 4). We conclude that P. costata is the senior name for this group of named forms. Therefore, mostly based on habitus, supporting genitalia or DNA barcode evidence, we make the following syn. nov. of P. costata Möschler, 1883: P. nigroapicalis Gaede, 1923, P. semicostalis Rothschild, 1909, P. alboatra (Rothschild, 1909), P. alboatra borussica (Seitz, 1921), P. unifascia (Druce, 1899), P. hamifera Dognin, 1907, and P. apicata Schaus, 1905.	en	Cock, Matthew J.

We have no DNA barcodes for this species and no specimens were available for dissection. Nevertheless, we note that the male resembles a female form of P. costata (Rothschild compared it to P. semicostalis), and this is a larger species (forewing ♂ 18 mm, ♀ 21 mm, compared to ♂ 13 – 17 mm, ♀ 19 mm for P. costata), so we consider it to be a valid species.	en	Cock, Matthew J.

BIN: BOLD: AAG 6256 (dx. doi. org / 10.5883 / BOLD: AAG 6256) Cramer described Phalaena Noctua onytes from Surinam (Cramer [1777], pp. 107, 150, plate 165 E) and Sphinx Adscita psamas Cramer, [1779] from Guyana (Berbice) and Suriname (Cramer [1779], pp. 72, 176, plate 234 G). We are not aware of any surviving type material (Cramer gives no details for P. onytes, while P. psamas was from the collection of Mr. A. Gevers), but Cramer’s figures (Fig. 6) serve to recognise both taxa; the dark grey hindwing in particular is distinctive. Hampson (1901) placed them both in the genus Neritos Walker, 1855, with psamas as the male of the female onytes. However, he subsequently realised that he had misidentified the male that he had used to illustrate the male of this species (i. e. Hampson 1901, Fig. 100) and described it as N. macrostidza Hampson, 1905 (Hampson 1905, 1920). In the same works, Hampson maintained N. psamas as the male of N. onytes, noted that in the male the yellow patches on costa and termen may be confluent or separate, and gave the distribution as Panama, Guyana, French Guiana, Bolivia and Peru. Rothschild (1910) held a different opinion and recognised N. psammas [sic] which he knew only from males from Trinidad and the Guianas, and N. onytes which he knew only from females from Suriname and British Guiana. However, Seitz (1920 – 1925) followed Hampson (1905, 1920) but added that the female as well as the male occurs with the yellow spots both separate and joined. Watson and Goodger (1986) reinstated Neritos psamas as a valid species, and placed onytes in Trichromia Hübner, [1819], of which it is the type species. They offered no explanation for the former action, but explained that most of the species placed in Neritos in their list would need to be transferred to Trichromia. Toulgoet (1991) clarified the composition of Trichromia, made Neritos a synonym and made the new combination Trichromia psamas. There have been no subsequent changes and both species are currently treated as valid and placed in Trichromia (Vincent and Laguerre 2014). Through these different changes, no one reported examining and comparing the genitalia of T. psamas and T. onytes. There are public barcodes for T. onytes in BOLD from Brazil and French Guiana (BIN BOLD: AAG 6256) and both morphs are included in this BIN (dx. doi. org / 10.5883 / BOLD: AAG 6256). In Trinidad and French Guiana, we have observed that T. onytes and T. psamas are the two principle morphs of a single variable species that occurs with the yellow discal forewing band uninterrupted (Fig. 7 A – B), with it split by the apical patch being joined to the basal-discal one (Figs. 7 C, E – F, 8 B), and occasionally as in intermediate morph with the band only very narrowly interrupted (Figs. 7 D, 8 A). We compared dissections of males of both main morphs from Trinidad and French Guiana and found the genitalia to be identical (Fig. 9). Noting also the occurrence of intermediate morphs, it is clear that Hampson (1901, 1905, 1920) and Seitz (1920 – 1925) were right, and the two names are synonyms, T. psamas being a syn. rev. of T. onytes. Where it is useful to distinguish these two morphs, they may be referred to as onytes morph and psamas morph.	en	Cock, Matthew J.

357987BDFF95FF8A68B585F8FD81FB5F.taxon	description	Figs. 10 – 13. BIN: BOLD: AAW 7134 (doi: pending) This species was described as Phalaena medarda from Suriname based on an undisclosed number of syntypes from Stoll’s collection (Stoll [1781], pp. 107 – 108). We are not aware of any surviving type material, so Stoll’s figure of a male (Stoll [1781], plate 345 F, shown here as Fig. 10) is the best indication we have of this species. Hampson (1901) treated V. medarda as a widespread species occurring from Mexico to the Amazon and Peru, and included V. mentiens Walker, 1854 (♂ type NHMUK, Venezuela), V. parva Schaus, 1892 (♂ type USNM, Peru, see Watson (1971 )), and three other taxa as synonyms. Rothschild (1910) treated this group as separate species, but Seitz (1919) reverted to treating them as forms. Subsequent authors have treated all species as valid (Watson and Goodger 1986, Zaspel and Weller 2006, Vincent and Laguerre 2014). Here we do not attempt to resolve the status of these taxa, but rather to fix the identity of V. medarda. The figure in Stoll’s plate (Fig. 10) falls within the range of variation of what we consider to be a single, moderately variable, sexually dimorphic species found both in French Guiana and Trinidad (Fig. 11). The limited number of male specimens from French Guiana are smaller (26 mm wingspan) than those from Trinidad (30 – 33 mm wingspan). Nevertheless, we compared male genitalia of specimens from both countries and found them identical (Figs. 12, 13). The extent of the yellow markings of the dorsal hindwing of males is variable (Fig. 11); the ventral hindwing mirrors the dorsal hindwing; a yellow patch on the ventral forewing may extend from the base as far as the middle of the wing, but is usually reduced and may be virtually absent. The female is similar in colour and markings (Fig. 11) although the dorsal forewing is darker brown, the yellow area of the ventral forewing is normally more extensive. Females are also significantly larger, typically 40 – 42 mm wingspan. We are only aware of one species of this appearance in both Trinidad and French Guiana. Given that these samples are from both east and west of the Suriname type locality, we conclude that we are justified in treating this species as V. medarda. We only have DNA barcode sequences available from French Guiana (BIN BOLD: AAW 7134), and conclude that this BIN should be treated as V. medarda. Public DNA barcodes in BOLD indicate that Central American material identified as V. medarda (BINs BOLD: ACE 9527, BOLD: ABY 7927, BOLD: ABZ 3957, and BOLD: ABZ 6726) will be found to represent different species. This species was first reported from Trinidad when Druce (1911) described V. birchi Druce, 1911 from Caparo, Trinidad, and Colombia based on an unspecified number of specimens. Seitz (1920 – 1925) incorrectly referred to this species as only occurring in Colombia. Hampson (1920) referred to Druce’s female type from Caparo being in coll. Joicey (now in NHMUK). Vincent and Laguerre (2014) report a male syntype from Caparo in NHMUK labelled ‘ type’ (Fig. 10). This specimen is one of two females from Caparo collected by F. Birch in NHMUK, and only females are curated as this putative species in NHMUK. Druce (1911) purportedly described the male of V. birchi only, but given the stated wingspan (1 ¾ inch, i. e. 44.5 mm) and the material in NHMUK, it seems clear that as Hampson (1920) indicated this was an error for the female, which as noted above is significantly larger than the male. Given that Druce named this species after Frederick Birch, who collected the Trinidad material, and Trinidad is listed as the first type locality by Druce (1911), and is given as the type locality by Hampson (1920), we designate the female specimen in NHMUK labelled ‘ type’ as the lectotype (Fig. 10). Kaye and Lamont (1927) treated V. birchi as a synonym of V. medarda (Stoll) (TL Surinam), although subsequent authors (Watson and Goodger 1986, Zaspel and Weller 2006, Vincent and Laguerre 2014) treated both as valid species. Based on the material examined, we are satisfied that only one species of this appearance occurs in Trinidad, and as shown above, this is V. medarda. It follows that Kaye and Lamont (1927) were correct to treat V. birchi Druce, 1911 as a female synonym of the male V. medarda Stoll, [1781].	en	Cock, Matthew J.
