Myotis comprises a diverse group of vespertilionid bats with worldwide distribution. Neotropical Myotis have an accentuated phenotypic conservatism, which makes species delimitation and identification difficult, hindering our understanding of the diversity, distribution, and phylogenetic relationships of taxa. To encourage new systematic reviews of the genus, a catalogue of the primary types and names is presented, current and in synonymy, for Neotropical Myotis. Currently 33 valid species (and three subspecies) are recognized, and their primary types are deposited in 12 scientific collections in the USA (30 types), Brazil (two types), England (two types), and France (one type). The names of 29 Neotropical Myotis species currently in synonymy were found. However, it is possible that some synonyms represent independent evolutionary lineages, considering recent results provided by taxonomic revisions.
Myotis compreende um grupo diverso de morcegos vespertilionídeos amplamente distribuídos ao redor do planeta. Myotis neotropicais têm um acentuado conservatismo fenotípico, o que dificulta a delimitação e identificação de espécies a partir de caracteres morfológicos, criando barreiras para a compreensão da diversidade, distribuição e relações filogenéticas entre os táxons. Visando encorajar novas revisões sistemáticas para o gênero, é apresentado este catálogo de nomes e tipos primários, válidos e sob sinonímia, para Myotis neotropicais. Atualmente, são reconhecidas 33 espécies válidas (e três subespécies) e seus tipos estão depositados em 12 coleções científicas nos EUA (30 tipos), Brasil (2 tipos), Inglaterra (2 tipos) e França (1 tipo). Compilamos 29 nomes de espécies de Myotis atualmente sob sinonímia. Entretanto, é possível que alguns desses sinônimos possam representar linhagens evolutivas independentes, considerando resultados recentes de revisões taxonômicas.

Introduction
Taxonomy is the discipline of Biology responsible for describing, classifying, and naming organisms, as well as hypothesize about the evolutionary relationships between taxa (Tancoigne et al. 2011). Therefore, understanding and organizing biological diversity is the primary task of the taxonomist. Taxonomic studies have profound implications in virtually all areas of the biological sciences, such as ecology, evolution, genetics, and epidemiology, in addition to directly influencing public policies focused on health and environment (Cracraft 2002; Pearson et al. 2011; Cook et al. 2020). Furthermore, knowing the real diversity of organisms on our planet is critical for the sustainable use of natural resources and for the management and conservation of species (May 1988), especially in the current biodiversity crisis, where the rate of extinction indicates that we are witnessing a sixth mass extinction (Ceballos et al. 2015, 2017).
Species are the central unit of taxonomy and the association between an unambiguous scientific name and a species is of paramount importance for a reliable biological information system (Wheeler 2004). For that, the existence of primary types, which are those specimens designated as the name-bearing representative of a species is essential. In addition to serving as a reference point for the existence of any organism, type-specimens are a particularly important source of information for scientists to track and unravel the taxonomic history of biologically complex groups, such as bats of the genus Myotis Kaup, 1829.
Myotis is the most speciose genus of bats and the second largest genus of mammals, with more than 140 extant species (MDD 2021). It is also the genus with the greatest area of distribution among non-human mammals (Moratelli et al. 2019a). The greatest diversity and abundance of Myotis is reported in temperate and subtropical areas (Nowak 1994; Moratelli et al. 2019a). However, recent systematic reviews have indicated that there is a high diversity of Myotis in the Neotropics (e.g., Larsen et al. 2012; Moratelli et al. 2011a, 2013, 2016, 2017, 2019b; Carrión-Bonilla and Cook 2020; Novaes et al. 2021a, b, c). Nevertheless, our knowledge of species limits, name validity, and distributional boundaries for several Neotropical Myotis species remains incipient.
Part of the taxonomic hurdle is due to the accentuated morphological conservatism and lack of specimen series covering all geographic distributions (Menu 1987; Smith et al. 2012; Moratelli et al. 2019a). On the other hand, molecular studies have revealed the existence of more independent evolutionary lineages than species recognized from morphology-based taxonomy (Larsen et al. 2012; Novaes et al. 2021a, b). This indicates the existence of hidden diversity possibly composed of multiple cryptic species, which challenges the delimitation of species and raises the need for new systematic reviews, especially those based on multiple lines of evidence.
To contribute to the organization of systematic knowledge about this genus, and to support future studies of taxonomy, we present a catalogue of the primary types of Neotropical Myotis. Later, we briefly comment on the validity and distribution of some species.
Materials and methods
The catalogue was mostly compiled by analysis of the specimens deposited in 12 biological collections: American Museum of Natural History (New York, USA), Field Museum of Natural History (Chicago, USA), Louisiana State University Museum of Natural Science (Baton Rouge, USA), Museum of Texas Tech University (Lubbock, USA), Museum of Vertebrate Zoology at University of California (Berkeley, USA), Kansas University Biodiversity Institute and Natural History Museum (Lawrence, USA), Natural History Museum, Los Angeles County (Los Angeles, USA), Smithsonian’s National Museum of Natural History (Washington D.C., USA), Natural History Museum, London (London, UK), Zoologisches Staats-Sammlung München (Munich, Germany), Muséum National D’Histoire Naturelle (Paris, France), Muséum d’Histoire Naturelle (Geneva, Switzerland), Museu de Zoologia da Universidade de São Paulo (São Paulo, Brazil), Universidade Federal Rural do Rio de Janeiro (Seropédica, Brazil). When it was not possible to visit the collection to examine the type specimen, the information was retrieved from the original species descriptions or other available bibliography (e.g., LaVal 1973; Carter and Dolan 1978; Carrión-Bonilla and Cook 2020) and by direct consultation with the curators of the collections. Abbreviations of biological collections cited in the text are available below.

The list of Myotis species adopted here is based on systematic reviews conducted for the genus Myotis in the Neotropical region (i.e., LaVal 1973; Bogan 1978; Moratelli et al. 2019a, b; Carrión-Bonilla and Cook 2020; Novaes et al. 2021a, b, c). Following LaVal (1973), we excluded species from the definition of Neotropical Myotis when their distributions extend from the Nearctic into the Neotropics. Geographical coordinates of type localities were retrieved, when available, directly from the original publications or by consulting the museum database and the gazetteer of Gardner (2008). In cases where they were not available, we used proximal coordinates of the locality from the search in the USA’s National Geospatial – Intelligence Agency (https://geonames.nga.mil/namesgaz/). We follow the International Code of Zoological Nomenclature (ICZN 1999) as a reference for the categories of type specimens.
The list of names was divided in two parts, the first with accounts of name-bearing type specimens of currently recognized species; and the second with accounts of name-bearing type specimens in synonymy. The accounts were arranged chronologically, following the date of taxa description. The format of accounts was inspired by Fisher and Ludwig (2015), but with modifications. Each account reads as follows: (i) Current name (for recognized species) or original published name (for names in synonymy) followed by the author’s or authors’ names; (ii) Original citation, including publication, volume, pages, and year of publication; (iii) Taxonomy, species original published name if different from the currently name, followed by information on subspecies, if any; (iv) Type designation as holotype, lectotype, paralectotype, neotype, or syntype, including collection number, age and sex, date collected and collector(s) name(s), and preparation of specimen; (v) Type locality: Verbatim locality as given in the original description or neotype designation, published restrictions, and supplementary data. Abbreviations are used for miles (mi), kilometers (km), feet (ft), and meters (m); (vi) Remarks, with additional information is provided as needed, but especially to explain types designated subsequent to description.
ResultsName-bearing type specimens of recognized species
For the 33 species (and three subspecies) of Neotropical Myotis currently recognized (Table 1), primary types are deposited in 12 zoological collections in the USA (eight collections), Brazil (two collections), England (one collection) and France (one collection). The USA is home to 30 primary types of Neotropical Myotis, while Brazil and England are home to two primary types each and France to one type specimen. The collections with the largest number of primary types are the Smithsonian’s National Museum of Natural History (11 types), followed by the American Museum of Natural History (eight types), both in the USA. The other collections have 1–4 type specimens each (Fig. 1).

Of all recognized Neotropical Myotis types, 28 are holotypes, six are neotypes, and one is syntype. Only one taxon lacks a type specimen (M.nigricansosculati), which presumably was destroyed. About 95% of the type specimens are preserved as skin and skull, with mandible; while only 5% are preserved in fluid (usually alcohol 70°GL). Most types (80%) are in a good condition, with complete skulls and untorn skin. The other 20% are damaged, especially the oldest ones. Damages include broken skulls, loss of bone elements, or torn skins (Figs 2–8).

https://binary.pensoft.net/fig/700686
Myotisruber (É. Geoffroy, 1806)
Annales du Muséum d’Histoire Naturelle 8: 187–205.
Taxonomy: Described as Vespertilioruber by Geoffroy Saint-Hilaire (1806: 204). Treated as monotypic (Wilson 2008; Moratelli et al. 2019a).
Neotype: USNM 115097, adult male collected on May 22, 1901 by W. Foster; skull, mandible, and skin.
Type locality: Sapucay (= Sapucai, Paraguarí), Paraguay (25°40'S, 56°57'W; ca. 200 m a.s.l.) by neotype designation (LaVal 1973: 45).
Remarks: The holotype was not specified by the author, who based his description on the Azara’s (1801) “chauve-sourris cannelle”. LaVal (1973) noted that D. C. Carter did not locate the specimen at the Muséum National d’Histoire Naturelle (Paris, France) or in any other European museum, concluding that it was lost or destroyed. The neotype was designated by LaVal (1973: 45), following the same reasoning presented for M.albescens (see below).
Myotisalbescens (É. Geoffroy, 1806)
Annales du Muséum d’Histoire Naturelle 8: 187–205.
Taxonomy: Described as Vespertilioalbescens by Geoffroy Saint-Hilaire (1806: 204–205). Treated as monotypic (Moratelli and Oliveira 2011; Moratelli et al. 2019a).
Neotype: AMNH 205195, adult female collected on June 2, 1963 by M. D. Tuttle; skull, mandible, complete post-cranial skeleton and skin.
Type locality: Yaguarón, Paraguarí, Paraguay (25°33'S, 57°17'W; ca. 200 m a.s.l.) based on neotype designation (LaVal 1973: 26).
Remarks: The holotype was not specified by the author, who based his description on the Azara’s (1801) “chauve-souris donzième”. LaVal (1973) noted that D. C. Carter was unable to locate a specimen in European zoological collections from Azara’s expedition. According to Cabrera (1958), É. Geoffroy based his description of Phyllostomalineatum (currently Platyrrhinuslineatus) on specimens collected in Paraguay and listed by Azara (1801) in the same publication in which he listed the specimen that Geoffroy described as Vespertilioalbescens. Cabrera stated that the specimen of P.lineatum was destroyed. LaVal (1973: 26) considered that the type specimen of V.albescens met the same fate and designated a neotype.
Myotisnigricans (Schinz, 1821)
Taxonomy: Originally Vespertilionigricans Schinz, 1821. We follow Bogan (1978) and Moratelli et al. (2019a) in recognizing three subspecies, and in treating M.carteri as a distinct species, instead of a subspecies of M.nigricans.
Myotisnigricansnigricans (Schinz, 1821)
In “Das tierreich eingetheilt nach dem Bau der thiere als Grundlage ihrer Naturgeschichte und der vergleichenden Anatomie von dem Herrn Ritter von Cuvier, volume 1”. Saugethiere und Vögel, Stuttgart and Tübingen, 894 pp.
Taxonomy: Described as Vespertilionigricans by Schinz (1821: 179).
Neotype: LACM 36877, adult female collected on October 14, 1968 by A. L. Peracchi; skull, mandible, and skin.
Type locality: Seropédica, 42 km S Rio de Janeiro, Brazil (22°45'S, 43°41'W; 33 m a.s.l.).
Remarks: The species was described based on a specimen collected by Prinz Maxililian zu Wied-Neuwied at Fazenda do Agá, near the Rio Iritiba, Espírito Santo, Brazil. Miller and Allen (1928) were not able to confirm the existence of this specimen. From a personal communication of D. C. Carter, that he could not locate it in among the important collection of Wied’s Brazilian specimens at the American Museum of Natural History, LaVal (1973: 9) presumed it has been lost and designated a neotype.
Myotisnigricansosculati (Cornalia, 1849)
In “Vertebratorum synopsis in Museo Mediolanense extantium que per novam orbem Cajetanus Osculati collegit annis 1846–47–1848 (…)”. Typographia Corbetta, Modoetiae, 16 pp.
Taxonomy: Described as Vespertilioosculati by Cornalia (1849: 11).
Type specimen: None. The specimen used in the original description was collected by G. Osculati between 1846 and 1848. Osculati’s collection deposited in the Museo di Storia Naturale di Milano, Italy, in 1848, was destroyed during World War II (Cagnolaro and Violani 1988; Moratelli et al. 2013).
Type locality: Eastern Ecuador.
Myotisnigricansextremus Miller & Allen, 1928
Bulletin of the United States National Museum 144: 1–218.
Taxonomy: Described as Myotisnigricansextremus by Miller and Allen (1928: 181).
Holotype: USNM 77670, adult female collected by the E. W. Nelson and E. A. Goldman on March 1, 1896; skull, mandible, and skin.
Type locality: Huehuetán, Chiapas, Mexico (15°01'N, 92°22'W; 91 m a.s.l.).
Myotislevis (I. Geoffroy, 1824)
Annales de Sciences Naturelles de Paris 3: 440–447.
Taxonomy: Described as Vespertiliolevis by Geoffroy Saint-Hilaire (1824: 444); currently monotypic (Moratelli et al. 2019a).
Syntype: MNHN type 203 (also referred to as MNHN 1997-1805), adult, sex unknown, collected by A. Geoffroy Saint-Hilaire (date not specified); mounted specimen, with skull removed and severely damaged.
Type locality: Southern Brazil.
Myotischiloensis (Waterhouse, 1840)
In “The zoology of the voyage of the H.M.S. Beagle, under the command of Captain Fitzroy, R.N., during the years 1832 to 1836”. Smith, Elder and Co, London, 97 pp.
Taxonomy: Described as Vespertiliochiloensis by Waterhouse (1840: 5); currently monotypic (Novaes et al. 2018; Moratelli et al. 2019a).
Neotype: FMNH 24029, adult female collected by J. Vera in 1923; skull partially damaged, mandible, and skin.
Type locality: Cucao, Chiloé Island, Los Lagos, Chile (42°38'S, 74°06'W; sea level).
Remarks: The original description was based on a specimen collected in January 1836 by Lieutenant Sullivan and given to C. R. Darwin during the H. M. S. Beagle voyage. Miller and Allen (1928) were unable to locate the specimen. LaVal (1973: 43) presumed it lost and designated a neotype.
Myotisoxyotus (Peters, 1866)
Taxonomy: Originally Vespertiliooxyotus Peters, 1866. We follow LaVal (1973) and Moratelli et al. (2019a) in recognizing two subspecies.
Myotisoxyotusoxyotus (Peters, 1866)
Monatsberichte der Königlichen Preussische Akademie des Wissenschaften zu Berlin 1867: 16–25.
Taxonomy: Originally Vespertiliooxyotus as described by Peters (1866: 19).
Neotype: LACM 36878, adult female collected by D. C. Carter on July 4, 1964; skull, mandible, and skin.
Type locality: Gruta Rumichaca, 2 mi E La Paz, Carchi, Ecuador (00°29'N, 77°50'W; ca. 2,600 m a.s.l.).
Remarks: The original description was based on an adult female preserved in spirit at “Zoologischen Cabinet zu München” (Peters 1866). Presumably this “Zoologischen Cabinet” is the same as the current Zoologische Sammlung des Bayerischen Staates (= Zoologische Staatssammlung München) in Munich, Germany. LaVal (1973) noted that D. C. Carter was unable to locate the holotype there in 1966, and he pointed out that many specimens in the museum in Munich were destroyed during World War II, and must be presumed lost. Therefore, LaVal (1973: 41) designated a neotype.

Type locality: Near Minimini, Tarapacá, Chile (19°10'S, 69°41'W; 1,800 m a.s.l.).
Remarks: The original description was based on three syntypes, probably collected in February 1885 in San Pedro de Atacama, Antofagasta, Chile, and deposited at Museo Nacional de Historia Natural (Santiago, Chile), including a mounted specimen (number 277), a skull (number 1007), and a fluid preserved specimen (number 276). LaVal (1973) argued these specimens are lost or, more probable, were destroyed. Novaes et al. (2022: 3) designated a neotype.
Myotisnesopolus Miller, 1900
Proceedings of the Biological Society of Washington 13: 123–127.
Taxonomy: Described as Myotisnesopolus by Miller (1900: 123). Treated as monotypic (Novaes et al. 2021a).

Myotisdominicensis Miller, 1902
Proceedings of the Biological Society of Washington 15: 243–244.
Taxonomy: Described as Myotisdominicensis by Miller (1902: 243). Currently monotypic (Moratelli et al. 2019a).

Vespertilioleucogaster Schinz, 1821
In “Das tierreich eingetheilt nach dem Bau der thiere als Grundlage ihrer Naturgeschichte und der vergleichenden Anatomie von dem Herrn Ritter von Cuvier, volume 1”. Saugethiere und Vögel, Stuttgart and Tübingen, 894 pp.
Taxonomy: Described as Vespertilioleucogaster (currently allocated to Myotis) by Schinz (1821: 180). Currently a junior synonym of Myotisalbescens (Miller and Allen 1928; LaVal 1973; Wilson 2008).
Lectotype: AMNH 385, adult (undetermined sex) collected by Maximilian, Prinz zu Wied-Neuwied (date not specified); taxidermized skin and skull not removed (see Avila-Pires 1965).
Type locality: Mucurí, Bahia, Brazil.
Vespertiliobrasiliensis Spix, 1823
In “Simiarum et Vespertilionum brasiliensium species novae (…)”. Typis Francisci Serephici Hübschmanni, Monaco, xvi + 72 pp.
Taxonomy: Described as Vespertiliobrasiliensis (currently allocated to Myotis) by Spix (1823: 63). Currently a junior synonym of Myotisnigricans (Miller and Allen 1928; Wilson 2008).
Type specimen: No specimen was designated by the author. Just like Carter and Dolan (1978), we have not found any reference specimens deposited in European collections.
Type locality: Brazil.
Remarks: The original name combination is preoccupied by Vespertiliobrasiliensis Desmarest, 1822 (currently Eptesicusbrasiliensis), hence, Fischer (1829) replaced it by Vespertiliospixii.
Vespertiliopolythrix I. Geoffroy, 1824
Annales de Sciences Naturelles de Paris 3: 440–447.
Taxonomy: Described as Vespertiliopolythrix (currently allocated to Myotis) by Geoffroy Saint-Hilaire (1824: 443). Currently a junior synonym of Myotislevis (LaVal 1973; Wilson 2008).
Syntypes: MNHN 842 (adult, undetermined sex), MNHN 843 (adult male), ZMB 3911 (adult, undetermined sex) collected by A. Geoffroy Saint-Hilaire, date not specified. All specimens are skins taxidermized (faded) with skull not removed.
Type locality: Rio Grande do Sul or Minas Gerais, Brazil.
Remarks: According to Turni and Kock (2008), the name polythrix is a nomen oblitum, due to page priority. This is the first available name (p. 443), whereas levis (nomen protectum) is on page 444 in Geoffroy’s publication (1824).
Vespertiliospixii Fischer, 1829
In “Synopsis mammalium”. Stuttgardtiae: J. G. Cottae, xlii + 752 pp.
Taxonomy: This name was proposed in replacement for Vespertiliobrasiliensis Spix, 1823, considering that this name was preoccupied by Vespertiliobrasiliensis Desmarest, 1822 (= Eptesicusbrasiliensis). Currently a junior synonym of Myotisnigricans (Miller and Allen 1928; Cabrera 1958; Wilson 2008).
Vespertilioparvulus Temminck, 1840
In “Monographies de mammalogie ou description de quelques genres de mammifères dont les espèces ont été observées dans les différens musées de l’Europe”. E. d’Ocagne et A. Bertrand, Paris, 141–272.
Taxonomy: Described as Vespertilioparvulus (currently allocated to Myotis) by Temminck (1840: 246). Currently a junior synonym of Myotisnigricans (Miller and Allen 1928; LaVal 1973; Wilson 2008).
Lectotype: RNH 17621, adult, sex undetermined, collected by J. Natterer (date not specified); skull severely damaged and skin faded.
Type locality: Brazil.
Vespertilioarsinoe Temminck, 1840
In “Monographies de mammalogie ou description de quelques genres de mammifères dont les espèces ont été observées dans les différens musées de l’Europe”. E. d’Ocagne et A. Bertrand, Paris, 141–272.
Taxonomy: Described as Vespertilioarsinoe (currently allocated to Myotis) by Temminck (1840: 247). Currently a junior synonym of Myotisnigricans (LaVal 1973; Wilson 2008).
Holotype: RNH 17635, adult female (collector and date of capture are unknown); skull partially damaged and skin faded.
Type locality: Surinam.
Vespertiliohypothrix d’Orbigny & Gervais, 1847
In “Voyage dans l’Amérique méridionale (…). P. Bertrand/Strasbourg: V. Levrault, Paris 4: 1–32.
Taxonomy: Described as Vespertiliohypothrix (currently allocated to Myotis) by d’Orbigny and Gervais (1847: 14). Currently a junior synonym of Myotisnigricans (Miller and Allen 1928; Cabrera 1958; Wilson 2008).
Holotype: MNHN AC 1903-41, sex, age, collector, and date undetermined; stretched skin only.
Type locality: Moxos [Beni], Bolivia.
Vespertilioisidori d’Orbigny & Gervais, 1847
In “Voyage dans l’Amérique méridionale (…)”. P. Bertrand/Strasbourg: V. Levrault, Paris 4: 1–32.
Taxonomy: Described as Vespertilioisidori (currently allocated to Myotis) by d’Orbigny and Gervais (1847: 16). Currently a junior synonym of Myotisalbescens (Miller and Allen 1928). However, based on observations made by Carter and Dolan (1978), Wilson (2008) did not include this name in the synonym list for M.albescens (see discussion in Remarks section)
Holotype: Probably MNHN 1997-1806, adult, sex undetermined; skull (damaged), mandible, and skin.
Type locality: Corrientes, Argentina.
Remarks: Rode (1941) indicated the specimen MNHN 865 as the holotype. However, Carter and Dolan (1978) show that there was confusion when interpreting a Cadre number, used to guide visitors about a specimen on display in the museum, with the catalog number. Thus, Carter and Dolan indicate that this is not the type specimen of this name and have not found any other specimen in collections in Europe that could be. One of us (RM) found the supposed specimen used for the description by d’Orbigny and Gervais deposited in the mammal collection of the Muséum National D’Histoire Naturelle, Paris, France. The presumable holotype (MNHN 1997-1806) is an adult (sex undetermined). The skull reassembles M.albescens, but the color pattern of the skin is not a Neotropical Myotis.

Holotype: ZSM 142, adult of undetermined sex, probably collected by A. F. W. Schimper (date not specified); skin only, slightly faded.
Type locality: St. Thomas [American Virgin Islands (Carter and Dolan 1978)].
Vespertilionubilus Wagner, 1855
In “Die säugthiere in abbildungen nach der natur mit beschreibungen von Dr. Johann Christian Daniel von Schreber (…)”. T. O. Weigel, Leipzig, xxvi + 810 pp.
Taxonomy: Described as Vespertilionubilus (currently allocated to Myotis) by Wagner (1855: 752). Currently a junior synonym of Myotislevis (see LaVal 1973; Wilson 2008).
Holotype: ZSM 121, subadult, sex undetermined; collector and date of capture are unknown; skin taxidermized with skull not removed.
Type locality: Brazil.
Vespertiliocinnamomeus Wagner, 1855
In “Die säugthiere in abbildungen nach der natur mit beschreibungen von Dr. Johann Christian Daniel von Schreber (…)”. T. O. Weigel, Leipzig, xxvi + 810 pp.
Taxonomy: Wagner (1855: 755) proposed the name Vespertiliocinnamomeus as a substitute for Vespertilioruber É. Geoffroy, 1806 believing that “chauve-sourris cannelle” from Azara (1801) was a Noctilio Linnaeus, 1766. However, Miller and Allen (1928) resolved Wagner’s misunderstanding, indicating that both the name ruber and cinnamomeus were based on the same specimen. Currently a junior synonym of Myotisruber (see Miller and Allen 1928; LaVal 1973; Wilson 2008).
Vespertiliokinnamon Gervais, 1856
In “Animaux nouveaux ou rares recueillis pendant l’expédition dans les parties centrales de l’Amérique du Sud (…)”. P. Bertrand, Paris, 25–88.

Proceedings of the Academy of Natural Sciences of Philadelphia 18: 279–288.
Taxonomy: Described as Vespertilioexiguus (currently allocated to Myotis) by Allen (1866: 281). Currently a junior synonym of Myotisnigricans (Miller and Allen 1928; Cabrera 1958).
Holotype: ANSP 5626 (= USNM 5373), adult female collected by S. Hayes (date not specified) is currently deposited in the mammal collection of the Academy of Natural Sciences of Drexel University (Philadelphia, USA); complete specimen preserved in alcohol with skin faded.
Type locality: Aspinwall, NG. (= Colón, Panama).
Vespertiliogayi Lataste, 1892
Actes de la Société Scientifique du Chili 1: 70–91.
Taxonomy: Described as Vespertiliogayi (currently allocated to Myotis) by Lataste (1892: 79), currently considered a junior synonym of Myotischiloensis (Miller and Allen 1928; Cabrera 1958; Wilson 2008).
Type specimen: None. We did not access the original publication describing the species. However, no specimens from Lataste that could match the description of M.gayi are available in collections in Europe or South America. Probably, these specimens are lost.
Type locality: Valdivia, Chile.
Myotisthomasi Cabrera, 1901
Boletín de la Sociedad Española de Historia Natural 1: 367–373.
Taxonomy: Described as Myotisthomasi by Cabrera (1901: 370). Currently a junior synonym of Myotisoxyotus (Miller and Allen 1928; LaVal 1973; Wilson 2008).
Type specimen: None. The original description was based on an adult female preserved in alcohol that, according to the author, was deposited in the mammal collection of the Museo Nacional de Ciencias Naturales (Madrid, Spain). However, a voucher number for the specimen was not listed by Cabrera (1901). Nevertheless, Carter and Dolan (1978) did not find the representative specimen in the MNCN collection and suspect that when moving to Argentina, A. Cabrera would have taken the type specimens. There are no specimens of Myotis that can represent the type of M.thomasi in the Museo de La Plata (Itatí Olivares, pers. comm.). We presume that probably this type specimen is lost.
Type locality: In the original description, Cabrera (1901) argued that he did not have reliable data on the geographical origin of the specimen, but that it was probably from southern Brazil. Later, Cabrera (1902) corrected this to “Archidona [sobre el citado río], Napo, Ecuador”.

Bulletin of the American Museum of Natural History 20: 29–80.
Taxonomy: Described as Myotischiriquensis by Allen (1904: 77). Currently a junior synonym of Myotisnigricans (Miller and Allen 1928; Cabrera 1958; LaVal 1973; Wilson 2008).

Discussion
Myotis is the most speciose bat genus in the Neotropics, with 33 species recognized currently (Bogan 1978; Moratelli et al. 2019a, b; Novaes et al. 2021a, b, c). Several species’ descriptions and revalidations have been recently proposed (e.g., LaVal 1973; Moratelli et al. 2011a, 2013, 2016, 2017, 2019b; Novaes et al. 2018, 2021a, b, c), and the evidence available points in the direction of hidden diversity (Clare et al. 2007; Larsen et al. 2012; Novaes et al. 2018; Carrión-Bonilla and Cook 2020). In this scenario of intense taxonomic change, a careful assessment of all name-bearing types is essential to the correct application of names to newly identified lineages and other nomenclatural acts. Below, we point out some nomenclatural issues still associated with name-bearing types of Neotropical Myotis.
Since its description, Myotisnigricans has been treated as a widely distributed species, and several subspecies have been recognized by different authors. However, recent studies have merged evidence indicating that M.nigricans is composite, as currently recognized, representing a complex of allopatric species (Moratelli and Wilson 2011a; Moratelli et al. 2011a, 2016, 2017, 2019b; Novaes et al. 2021b). The name nigricans seems to apply to Atlantic Forest populations from southeastern Brazil and southern South America, considering the type locality (Moratelli and Wilson 2011a; Moratelli et al. 2013, 2017). Therefore, it is necessary to reassess the taxonomic status of populations from tropical Mexico, Central America, and northern South America currently recognized as M.nigricans (and its subspecies). In this case, names currently treated under synonymy might apply to these potential new taxa.
Currently, 14 names are under synonymy of M.nigricans and can be available to use after a careful taxonomic review that considers the examination of type specimens. An example is the name Vespertiliosplendidus Wagner, 1855 (= Myotissplendidus), described based on a specimen from “St. Thomas” (Wagner 1855). Carter and Dolan (1978) indicated the type locality as “St. Thomas [American Virgin Islands]”, which was followed by subsequent authors (e.g., Wilson 2008). However, Myotis apparently does not occur either on the US Virgin Islands (Bacle et al. 2008) or on the nearest Caribbean islands (Puerto Rico, British Virgin Islands, Anguilla; Timm and Genoways 2003; Genoways et al. 2007). On the other hand, “St. Thomas” is a locality on the Caribbean Island of Barbados, where M.nyctor is the only species known to occur (Novaes et al. 2021a). Based on this scenario, Myotissplendidus is a very rare (or extinct) species (and unique representative of the genus) on the US Virgin Islands; or the geographical origin of the holotype of Myotissplendidus is Barbados, not US Virgin Islands, and the name is the senior synonym of Myotisnyctor. In any case, Myotissplendidus is unlikely to be a synonym for Myotisnigricans, considering the biogeographical history of colonization of the Caribbean, where each island has its own unique species of Myotis, and there is no evidence of the occurrence of M.nigricans as recognized by Moratelli et al. (2017) and Novaes et al. (2021a).
Another important issue is the validity of some names occasionally found in the literature on Myotis taxonomy. In their catalogue of type specimens of neotropical bats deposited in selected European museums, Carter and Dolan (1978) listed “Vespertiliocarbonarius Wagner” based on a specimen (ZSM 124) from Brazil obtained by J.F. Brandt, whose label reads “Vespertiliocarbonarius Wagn. / 1843 / Brandt / Brasil”. This specimen (taxidermized skin with skull not removed) was examined by us and it resembles M.riparius in size and the fur texture, length, and coloration. However, as with Carter and Dolan (op cit.), we were also unable to locate the publication with the species description. It is not impossible that this name was formally published (considering the vast, and sometimes rare, production of Wagner). However, if a publication containing the species description is found, we suggest that Vespertiliocarbonarius should be treated as a nomen oblitum, following article 23.9.1 from ICZN (1999).
For another example, Cornalia (1849) assigned the name “Vespertilioquixensis Osculati” to the synonymy of Vespertilioosculati (= Myotisnigricansosculati). In an introduction to the facsimile reprint of Cornalia’s (1849) publication, Cagnolaro and Violani (1988) recommended treating V.quixensis as a nomen nudum, but the name became available in the combination Phyllostomusquixensis Osculati, 1854: 53. It is possible that the description of quixensis appeared in the first edition of the Osculati’s publication; however, we have not been able to examine that publication due to its rarity.
Myotis comprises a diverse group in number of species compared to other neotropical bat genera. However, its species richness does not reflect its phenotypic diversity, characterized by a low morphological differentiation (Ghazali et al. 2017; Moratelli et al. 2019a). Due to the large number of species names proposed, this catalogue puts together information on name-bearing types of species treated as valid or under synonymy as an aid for future taxonomic works.
