FE1887BE3933FFD9EFACFD7D1004FDCE.taxon	discussion	Remarks: This is the best series at the MHNG. Besides numerous subsequent misidentifications, there are 4 specimens that still bear a label handwritten by F. - J. Pictet and that were collected at Genthod, near Geneva. Only these 4 specimens can be considered syntypes of E. glaucops.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3932FFD9ECC5FD7A1065FB32.taxon	discussion	Remarks: F. - J. Pictet mentioned that the single specimen he saw came from the collection of the Museum of Natural History in Neuchâtel and had been made accessible by M. Coulon. According to Dr Jean-Paul Haenni (in litt.), former curator at the Museum in Neuchâtel, the specimen is not in their collections. The specimen was already in a bad state when F. - J. Pictet described it. It is now presumably lost.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J. Pictet and A. - E.

FE1887BE3932FFD9ED30F8521521F91F.taxon	discussion	Remarks: The specimen, sent by Kollar, is slightly damaged (distal half of right fore wing, right middle leg, left hind leg and right cercus missing). Most probably it was collected by Carl August v. Hügel (1759 - 1870), who travelled in southern India and Punjab in 1831 - 1836. His material was acquired in 1839. The most complete description of this species was provided by Chopra (1928) based on new material from India. Moreover, he had the opportunity to examine the holotype deposited in Vienna. His material has in common with the type: (i) the costal field of the forewing tinted with violet, (ii) a longitudinal violet band dorsally on the abdomen, (iii) the coloration of the fore legs of the female. It differs, however, by the number of intercalaries in the cubital field (4 - 5 on the type specimen but 6 in the Indian material) and by the length of the terminal filament, equal in length to the cerci according to F. - J. Pictet’s description and drawing. In the type specimen the right cercus is broken near the base (remainder missing), the left cercus and the terminal filament are apparently of equal length, but in fact the tip of the left cercus is missing and the correct measurements presumably correspond with Chopra’s material. The paracercus is obviously shorter in the Indian material (“ in the female the lateral ones are 11 - 13, while the median seta is 7 - 8 mm long ”; Chopra, 1928: 128). According to Lestage (1921) the single female from Tonkin (Vietnam) and referred to E. indicus possessed a terminal filament as long as its cerci. Ulmer (1913) reported several females of E. indicus from Java. According to his short description, the terminal filament is shorter and the cubital field of the fore wing is slightly different to what Lestage observed in his Vietnamese specimens.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3932FFDAEF93F90B1303F81B.taxon	discussion	Remarks: F. - J. Pictet briefly mentioned this species in the addenda of the genus Palingenia, saying he had not seen any specimens and based his diagnosis on the drawing provided by Savigny (of a female subimago), in accordance with article 12.2.7 of the International Code on Zoological Nomenclature (International Commission of Zoological Nomenclature, 1999). However, Eaton (1871) mentioned that several specimens were kept in F. - J. Pictet’s collection, and that later F. - J. Pictet gave him a specimen (Eaton, 1883). In the MHNG two specimens are still present: a male imago (Fig. 3), 620 48 Egypte coll. Pictet / Savignyi Pict. [purple label broken in four pieces], and a male imago, 620 48 Egypte coll. Pictet / M. De Selys Longchamp. None of them can be considered as type material. The type material should be in Savigny’s collection in the National Museum of Natural History in Paris, but a recent visit by the first author failed to find it. However, this is of no consequence for the validity of the species name (see International Commission on Zoological Nomenclature, 1999: article 73.1.4).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3931FFDAEF82FEEF12D3FBBA.taxon	discussion	Remarks: Eaton (1871) already mentioned that only subimagines were present in the collection, but none could be found during our study. The status of this species was enigmatic for a long time until Thomas (1968 b) clarified it and suggested that the concept of E. fluminum had been applied differently among the mayfly taxonomists of the first half of the 20 th century. Thomas (1968 b) convincingly demonstrated that F. - J. Pictet’s concept of E. fluminum corresponds to that of E. dispar Curtis, 1834.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3931FFDBEF86FB69105AFACE.taxon	discussion	Remarks: F. - J. Pictet proposed the new taxon with reservations in a note (F. - J. Pictet, 1843: 169): “ Il y a probablement une nouvelle espèce ... Si c’est bien une espèce distincte, elle devra porter le nom de B. forcipula, nom sous lequel elle m’a été communiquée par M. Kollar ”. As the description of F. - J. Pictet was expressly based on material (and / or manuscript notes) provided by Kollar from Austria, those specimens are syntypes (International Commission on Zoological Nomenclature, 1999: article 73.2.1). While proposed only conditionally by F. - J. Pictet, the name is clearly available under article 11.5.1. Although Ulmer (1921: 241) stated “ Typen dieser Art finde ich nicht ” [I cannot find types of this species], he nevertheless mentioned two of the above listed syntype specimens, which he (correctly) identified as Ecdyonurus venosus. Among the specimens present in the NMW collection and placed under the species name E. forcipula, three pinned specimens were without doubt collected by Kollar and bear his handwritten label. Considering all the circumstantial evidence, these specimens must be considered as part of the type series (syntypes) although they bear no direct reference to F. - J. Pictet. The concept of E. forcipula has been interpreted differently among taxonomists in the past (e. g., Meyer-Dür, 1874: 314; Eaton, 1887: 286; Rostock, 1888: 154; Ulmer, 1929: 32; Schönemund, 1930: 23; Kimmins, 1942 a: 123; Kimmins, 1942 b: 504) and redescriptions have almost certainly been based on material that belongs to several taxa. Bauernfeind (1990: 76) stated that Kollar’s specimens belong to Ecdyonurus venosus but did not propose a formal synonym. In the meantime a neotype for Ecdyonurus venosus was proposed (Bauernfeind & Haybach, 2012) and subsequently fixed (International Commission on Zoological Nomenclature, 2015) which enables us to formally place Baetis forcipula F. - J. Pictet, 1843 (currently in Ecdyonurus) in the synonymy of Ephemera venosa Fabricius, 1775 (currently in Ecdyonurus). The thorough description of Ecdyonurus forcipula by Thomas (1968 b: 61) denotes a taxon new to science, for which the name Ecdyonurus (Ecdyonurus) alaini sp. nov. is proposed in honour of our friend Alain Thomas and his outstanding work on Ephemeroptera.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3930FFD4EF85F9C81349F854.taxon	discussion	Remarks: F. - J. Pictet gave a very brief description of this alpine species. Eaton (1888) was unable to place it with certainty among the Heptageniidae. No original material of this taxon could be traced. In the MHNG there is one female imago with the following label data “ 620 Burgdorf 48 coll. Pictet / Baetis montana P. Bgdf 9 Juni ”, obviously a specimen collected and identified by Meyer-Dür and most probably belonging to the so called Ecdyonurus helveticus species-group. The name Baetis montana F. - J.

FE1887BE3930FFDBECF0FA7B159EFC5E.taxon	diagnosis	Diagnosis: The new taxon is characterized by the following combination of characters: Imagines usually slightly smaller than those of E. venosus (fore wing length of holotype 14.0 mm), overall abdominal colouration more sombre, dull yellowish brown (in E. venosus more reddish), laterally a rather indistinct triangular brownish blotch in posterior half of abdominal segments 2 - 8 (frequently missing; a distinct triangular dark red to violet-black blotch in posterior half of abdominal segments in E. venosus), posterior margin of forceps base almost straight (distinctly convex in E. venosus) with (rarely without) low, broad and rounded lateral teeth. Penis lobes (Fig. 4 A) slightly more massive, basal sclerite more broadly triangular, with few or no teeth along posterior margin (basal sclerite narrowly triangular, with strong teeth along posterior margin in E. venosus), median titillators with a longitudinal row of inconspicuous subapical teeth or smooth (median titillators with a longitudinal row of strong subapical teeth in E. venosus). Last instar larvae are characterized by rather strong, almost straight, apically broadly rounded pronotal processes (Fig. 4 B) (apically bluntly pointed in E. venosus) and comparatively weak and short lateral processes (Fig. 4 C) (1 / 5 of segment length) on abdominal sterna 2 - 9 (strong and long, 1 / 3 of segment length in E. venosus).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE393EFFD5ED34FCC1109BF875.taxon	discussion	Remarks: The two male specimens (considered by Sowa as part of the original type series) are pinned on the same needle, and the lower one has been designated as lectotype by Sowa (1971: 897). It bears the following labels: 620 Genthod 48 Genève coll. Pictet / Baetis semitincta [in Sowa’s opinion probably F. - J. Pictet’s handwriting] / Rhithrogena semitincta (Pictet), lectotype [= semicolorata (Curtis)] Det. R. Sowa. This taxon has been controversial for a long time. Eaton (1888) mentioned several variants in the coloration of the wings, which he did not consider of taxonomic value. Kimmins (1936) proved that the concept of R. semicolorata sensu Eaton (1888) fits at least two species and he re-established R. semitincta as a valid name. Finally, Sowa (1971) studied the type series, proposed R. semitincta (F. - J. Pictet, 1843) as a junior subjective synonym of R. semicolorata (Curtis, 1834) and described R. semitincta sensu Kimmins (1936) nec R. semitincta (F. - J. Pictet, 1843) as a new species, R. picteti Sowa, 1971.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE393EFFD6EF8FFC0B1073F86A.taxon	discussion	Remarks: Eduard Friedrich Poeppig (1797 - 1868) travelled in Cuba (1823 - 24) and Pennsylvania (1824 - 26). In 1826 he departed for Valparaiso and spent several years performing scientific explorations throughout Chile, Peru and Brazil during 1827 - 1832. Material from his travels was acquired by the NMW in 1840. In later years he also sold specimens from different sources (Cuba 1843, Port Natal 1845, etc.). Ludwig Parreyss (1796 - 1879) was an established natural history dealer (mostly in insects and birds) in Vienna and material has been very frequently acquired from him by the NMW. McCafferty & Bae (1992: 70) in their discussion confused part of the labels and erroneously reported Hagen’s label as being with the male subimago. None of the specimens, however, can be identified with any degree of certainty and McCafferty & Bae’s decision to consider the name Baetis flaveola F. - J. Pictet, 1843 as a nomen dubium should be followed.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J. Pictet and A. - E.

FE1887BE393DFFD6EFF2FAE915C7F870.taxon	discussion	Remarks: F. - J. Pictet examined a single female from the National Museum of Natural History in Paris. This species certainly does not belong to the genus Ecdyonurus nor to the family Heptageniidae, which is absent from South America. The combination with Siphlonella (Oniscigastridae) proposed by Flowers & Peters (1981) is mainly based on the colour pattern. The holotype is presumably lost and the name Baetis guttata should be considered a nomen dubium.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE393CFFD7ECCFFEEF11F4F905.taxon	discussion	Remarks: F. - J. Pictet mentioned “ Les deux exemplaires figurés … ” and described the male imago and [female] subimago, attributing the latter only doubtfully (F. - J. Pictet, 1843: 189 “ Id.? Pseudimago, Planche XXIV, FIG. 2 ”; F. - J. Pictet, 1845: 10 “ Probablement le mâle [sic] subimago ... “). According to the International Commission on Zoological Nomenclature (1999: article 72.4.1), the male specimen is therefore the holotype by monotypy. Kollar probably had sent three specimens to F. - J. Pictet: a male (listed above), a female subimago (Lotz. 12 [= Johann Lhotsky, who collected in New South Wales in 1832 - 1838] / australasica subimago), and a female (Pictet vidit / Lotz. 11). Ulmer (1921: 243) listed “ drei Typen [three types] ” but obviously confused one label. The remark “ Sidney ” [probably in F. M. Brauer’s handwriting] refers to an additional male specimen which was collected during the Novara Expedition in November 1858 but was not examined by F. - J. Pictet. Ulmer (1920 b) synonymized B. australasica F. - J. Pictet, 1843 with B. costalis Burmeister, 1839, but Harker (1954) recognized that Baetis costalis Burmeister, 1839 is a homonym of B. costalis Curtis, 1834 and so she reinstalled the older synonym as the valid name of the species.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE393BFFD0EFADFE6D15CEF9AF.taxon	discussion	Remarks: Some specimens are more or less damaged but on the whole in comparatively good condition (Fig. 6 B-C). Heinrich Wilhelm Schott collected in Rio de Janeiro during 1817 - 1821, where he was practically all the time restricted to the vicinity of the city (Schott, 1822). Two of his excursions reached Canta Gallo (= Cantagalo 21 ° 58 ” S 42 ° 22 ” W) and Macacú (22 ° 42 ’ S 43 ° 02 ” W). Ulmer (1921: 244) listed “ acht Typen ” and provided a redescription of the material. It seems probable that Kollar sent just a sample of 2 specimens to F. - J. Pictet (he based his description on “ ... deux exemplaires secs ”), and afterwards labelled the complete series. F. - J. Pictet, however, seems to have recognized this and according to the International Commission on Zoological Nomenclature (1999: article 72.4.1.1), the seven existing specimens constitute the type series. Leptohyphodes inanis is the type species of the genus Leptohyphodes Ulmer, 1920 a and is so far only known from Brazil (Domínguez et al., 2006).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3938FFD3ED34F9AB1423FB86.taxon	discussion	Remarks: F. - J. Pictet wrote “ Je ne connais que la femelle subimago de cette espèce … elle m’a été communiquée par le musée de Vienne ”. It is, however, rather doubtful whether the specimen in the NMW actually represents the type specimen: female subimago / Caenis argentata? Kollar lactea Hffm. [Kollar’s handwriting] / Caenis horaria (L.) det. Malzacher 1983 [no collector’s label, no locality]. Ulmer (1921: 248) erroneously quoted three male subimagines in the NMW carrying F. - J. Pictet’s label: “ ... davon stammen zwei aus Sizilien, eins aus Ischl. ”. None of these specimens actually bears F. - J. Pictet’s label nor could they have represented type material, and most probably Ulmer’s remark was based on a confusion with later acquisitions from Sicily not seen by F. - J. Pictet. Two additional male specimens and one female (in the NHW, all without labels) have been transferred to glycerin: “ Caenis horaria (L.) sub nom. C. lactea (Pict.) det. Malzacher 6. 1983 ”. None of them can be considered to represent type material. Caenis horaria has so far not been recorded from Sicily and in our opinion it is most likely that Kollar incorrectly labelled a specimen of unknown origin at a later time. The specimen in question lacks the “ Pictet vidit ” label as well as any evidence concerning its origin, and it therefore seems justified to consider the name Caenis argentata F. - J. Pictet, 1843 as a nomen dubium.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J. Pictet and A. - E.

FE1887BE3938FFD3ED29FC641070FA7F.taxon	discussion	Remarks: In the MHNG there is one specimen (female subimago) which bears the name Caenis halterata Fabr. and originates from Burgdorf (coll. Meyer-Dür). This specimen belongs to Caenis luctuosa (Burmeister, 1839). Without any new available data, we accept the synonymy proposed by Eaton (1871) and followed by Malzacher (1986), but in our opinion C. grisea could also be considered a junior subjective synonym of C. luctuosa (Burmeister, 1839).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3938FFCCEF9EFBA310C8FDBF.taxon	discussion	Remarks: Theodor Kotschy (1813 - 1866) travelled the White and Blue Nile (Cairo to Torra, El Obeid, Torra, Karthum, Beni Shanqul) during 1836 - 1839. Material from this expedition was acquired by the NMW in 1839. In his redescriptions Ulmer (1916: 14; 1921: 248) quoted “ vier Typen [four types] ” misreading the collector’s acronym for “ No. 21 ”. The fourth specimen, however, does not represent type material and actually originates from a series collected by Josef Franz Natterer (1819 - 1862) in “ Egypt ” [Karthoum], acquired by the NMW in 1858 and not seen by F. - J. Pictet. Beside this material, and as F. - J. Pictet mentioned “ … et je la possède aussi dans ma collection ”, four specimens are located in the MHNG. They were found under the name Caenis lactella Eaton, 1884 (a synonym of C. horaria) and all bear the same label: 620 48 Europe centr [ale] coll. Pictet. As no Tricorythus species has ever been reported from Europe, we can conclude that this is an example of the poor care the collection has suffered. These specimens fit the description given by F. - J. Pictet and may well constitute part of the original type series. This material is currently in ethanol. Eaton (1868) based his genus Tricorythus on Caenis varicauda F. - J. Pictet, 1843 which was recently redescribed by Kluge (2010).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3927FFCCED3EFD6B1088F8CA.taxon	discussion	Remarks: The type specimen, denoted “ femelle imago ” by F. - J. Pictet, corresponds with his description and illustration. It had presumably been collected by Georg Dahl (1769 - 1832), naturalist and dealer in natural history specimens, who collected in Sardinia and whose respective material was acquired by the NMW in 1826. Ulmer (1921: 248) mentioned two female specimens with F. - J. Pictet’s label, originating from Sardinia, but Pictet (1843) expressly mentionned that he examined only one specimen: “ L’individu que j’ai eu à ma disposition ... ”. The second specimen, with protruding eggs and labelled “ Pictet vidit ” (but without collector’s label or locality) which corresponds with Ulmer’s description, was doubtfully identified as “ C.? luctuosa (Burm.) det. Malzacher 1983 ”. Another female specimen, labelled “ C. oophora Pict. Sardinien (Mann) [probably Kollar’s handwriting] / Pictet vidit ” does not correspond with F. - J. Pictet’s description and was probably subsequently identified by Kollar, but it had not been examined by F. - J. Pictet. It had either been obtained from or collected by Josef Johann Mann (1804 - 1889), who travelled Corsica in 1855 and Sicily in 1858 (Rogenhofer, 1889). In the light of this poor and contradictory evidence, the name C. oophora Pictet, 1843 is probably best considered a nomen dubium.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

This taxon has been quite enigmatic for a long time although additional descriptions had been provided by Hagen (1855), Ulmer (1921), Needham & Murphy (1924) and Puthz (1973 a). Domínguez et al.

Two damaged paralectotypes are still pinned, but only the thorax of one specimen and the thorax and hind legs of the other are still present. One specimen has a label saying “ Hind wing of Epeorus sylvicola Ed Pictet, Eaton exam [inavit]. “ and the other the following: “ Epeorus sylvicola (A. - E. Pictet) Syntypes because of fragmental character not designated as paralectotypes PUTHZ, 1971 ”. Since Puthz (1973 c), it has been admitted that the central European species known as Epeorus assimilis Eaton, 1885 is a junior subjective synonym of E. sylvicola. However, more recent investigations by Thomas et al. (2000) indicate that E. assimilis is a closely related but distinct taxon. Hence, E. sylvicola seems restricted to the Iberian Peninsula and also to North Africa.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3926FFCEEF85FB5811EEFC3D.taxon	discussion	Remarks: From F. - J. Pictet’s text and illustrations it is clear that he based his descriptions on material from the surroundings of Geneva. Obviously Eaton (1871) based his description of Leptophlebia picteti only on F. - J. Pictet’s description of P. marginatus, which he literally translated into Latin, and according to the International Commission on Zoological Nomenclature (1999: article 72.4.2) the type series consists of the material originally examined by F. - J. Pictet. When Eaton erected the genus Choroterpes Eaton, 1881, he based it exclusively on his new species C. lusitanica Eaton, 1881. It was only later (Eaton, 1884: 105) that he considered C. lusitanica a junior subjective synonym of C. picteti and consequently used this name for the type species of Choroterpes. In the MHNG exists at least one specimen which had been examined by Eaton: male / 620 48 Espagne coll. Pictet / 66 / 31 / M. 2 Selys Longchamps / Chloroterpes [sic] Picteti Eaton Eaton type. The material is in alcohol and in poor condition, in several pieces, and it is completely faded, as are the labels. The origin of the specimen (Spain) indicates that it came from A. - E. Pictet’s collection and was seen and labelled by Eaton himself, but obviously at a later time than the original description in 1871. The specimen is most probably not part of the original type series and therefore not available for lectotype fixation (International Commission on Zoological Nomenclature, 1999: article 74.1) and Eaton’s remark on the label (“ type ”) cannot be understood as a valid neotype designation (International Commission on Zoological Nomenclature, 1999: article 75.3). There is also a pinned specimen in the MHNG placed under the name Leptophlebia marginata L. It is a male subimago with the following labels: 620 Burgdorf 48 Suisse coll. Pictet / Pot. Marginatus. This specimen (probably collected by Meyer-Dür) also belongs to C. picteti but can also not be considered to represent type material.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

Pictet collection at the MHNG there are several pinned specimens which had also been studied by Kimmins (in part; 1936) and by Sowa. However, contrary to what Sowa stated, these specimens do not constitute the “ original material ” studied by F. - J. Pictet (“ … commune dans les ruisseaux des environs de Genève ”). The old MHNG series consists of 12 male imagines labelled: 620 Hindelbank 48 Suisse coll. Pictet / Rh. semicolorata Curtis / Rhithrogena picteti Det. R. Sowa.

FE1887BE3925FFCFEF97FA2D1057FAD6.taxon	discussion	Remarks: The status of the NMW material is not altogether clear; these are probably syntypes (male imagines). The first specimen had been collected by H. W. Schott during 1817 - 1821 in Brazil, Rio de Janeiro province. Although F. - J. Pictet stated “ L’exemplaire figuré m’a été communiqué par le Musée de Vienne, … ”, Ulmer (1921: 239) found two male specimens arranged under the name Palingenia albicans Pictet and identified the second specimen as Campsurus truncatus Ulmer, 1920 a. It is not known whether F. - J. Pictet really examined both specimens or rather Kollar later added a second male when he labelled the material. F. - J. Pictet’s description and illustration, however, agree with the specimen labelled “ type ” by Ulmer, suggesting that this specimen actually represents the holotype by monotypy. Palingenia albicans F. - J. Pictet, 1843 nec Ephemera albicans Percheron, 1838, which was transferred as Campsurus albicans by Eaton (1883), has a long and controversial nomenclatural history. Palingenia albicans F. - J. Pictet, 1843 is actually a misidentification, not a formally established species name. Ulmer (1924 b) based his genus Asthenopodes on this incorrectly named taxon, and Hubbard (1975) proposed a valid name (nomen novum) in honour of F. - J. Pictet, because the speciesgroup name used by Ulmer was not available (speciesgroup name wrongly applied through misidentification; International Commission on Zoological Nomenclature, 1999: article 49).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

[abdomen broken, remaining parts with fungal growth] (Fig. 9 B). Remarks: This specimen is intriguing. The identification made by Eaton is correct, because it is based on the peculiar arrangement of veins in the cubital and anal fields (Fig. 9 A). Eaton (1885) did not mention this specimen from Italy, restricting the distribution of the species to the type locality in Holland. It is therefore possible that the specimen was identified by Eaton after the publication of his monograph. The first record of A. fragilis from Italy was by Turin et al. (1997). These authors suspected this surprising discovery to be due to a recent introduction with fishes from Eastern Europe. The fact that this specimen was collected more than 150 years ago indicates that further investigations on the distribution of this species in Italy are needed and that its occurrence may be natural. The recent discovery of A. fragilis in Croatia points in the same direction (Cuk et al., 2015).	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

FE1887BE3923FFC9EF8FF8C413F5FC6B.taxon	discussion	Remarks: This specimen has certainly been collected by A. - E. Pictet on his way back to Geneva when he left San Ildefonso in mid July 1859. The identification by Eaton followed the common interpretation of Baetis aurantiaca at that time. Since then, it has been shown that Burmeister’s concept of R. aurantiaca applies to an Ecdyonurus species (Puthz, 1973 b). Rhithrogena cincta has been redescribed by Thomas (1968 a), who designated from Navás’ collection a lectotype originating from Vilallonga in the Spanish Pyrenees. The specimen collected by A. - E. Pictet completely fits the diagnosis proposed by Thomas (1968 a), particularly in the shape of the styliger plate with well marked postero-lateral protuberances, in the marking of the abdomen, and in the marking of the coxae with two elongated stripes (see Thomas 1968 a: pl. I, figs 2 - 3, pl. II, fig. 2 and Fig. 10). Penes lobes clearly correspond to those of the diaphana - group, but differences between R. diaphana and R. cincta are insignificant. The status of this species should be solved on the basis of new material. This specimen is only the second one known for this species.	en	Sartori, Michel, Bauernfeind, Ernst (2020): Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.
