Myotis is the largest genus of the Vespertilionidae family. It presents a cosmopolitan geographical distribution and is considered an example of adaptive radiation, however, with only nine species recorded for Brazil. This study synthesized aspects of the geographic distribution by map punctuating the main records for each species, karyotype, and phylogeny in contribution to the understanding of the taxonomic complex of the genus Myotis in Brazil. A search in bibliographic databases (e.g., Web of Science and SciElo) was carried out using keywords. The phylogeny study was based on the sequencing of a specimen of Myotis ruber collected in a fragment of the Altantic Forest of Minas Gerais; this specimen was deposited at the Newton Baião de Azevedo Museum of Zoology. The genus showed to be widely distributed in the Brazilian territory, with Myotis nigricans being the most widespread. In addition, high karyotypic conservatism was observed in all species of the genus. The phylogenetic ana...
Distribution and natural history ofMyotis lavali(Chiroptera, Vespertilionidae)
Journal of Mammalogy, 2013
LaVal's myotis (Myotis lavali) was recently described from the M. nigricans complex based on specimens from the Caatinga of northeastern Brazil. We present new distributional records for the Alto Chaco in Paraguay and for the Atlantic Forest of Brazil and Paraguay. These new records extend the distribution of the species approximately 2,000 km southwest and 400 km east, and document its co-occurrence with M. nigricans. Both results have taxonomic and ecological implications for M. lavali. Additionally, we provide comments on its natural history and reproduction.
Catalogue of primary types of Neotropical Myotis (Chiroptera, Vespertilionidae)
ZooKeys, 2022
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. Resumo 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.

We describe a new species of bat in the genus Myotis (Vespertilionidae, Myotinae) from the coastal mountains of Venezuela. The new species (Myotis handleyi, sp. nov.) can be distinguished from other South American congeners by the following set of traits: dorsal fur long, silky, and bicolored with burnished tips; skull long; rostrum long and broad; frontals moderately to steeply sloping; sagittal crest absent or very low; plagiopatagium broadly attached to the foot at the level of the base of the toes; fringe of hairs along the trailing edge of uropatagium absent; and fur on uropatagium not reaching knees. We review Colombian and Venezuelan samples of Myotis, covering all of the currently recognized species known from these countries. Based on our analyses, we provide a sketch of the taxonomic diversity of the genus in Colombia and Venezuela, along with a key to their identification. Among other conclusions, we elevate M. nigricans caucensis to the species level; confirm that populations of M. nigricans from the opposite sides of the Andes represent the same taxon; retain J.A. Allen's names M. esmeraldae, M. bondae, and M. maripensis in the synonymy of M. nigricans; and document clinal variation in size along an altitudinal gradient for M. nigricans, with larger specimens from higher elevations. This research, based on museum and field collections, is one of a series of studies by the senior author re-evaluating species limits among Neotropical Myotis.
TWO NEW SPECIES OF MYOTIS (CHIROPTERA: VESPERTILIONIDAE) FOR ARGENTINA
Seven new species of Myotis have been recently described from South America, elevating to 20 the total number of species of the genus recognized for the region. Myotis izecksohni and Myo-tis lavali were recently described from the States of Río de Janeiro, Paraná and Pernambuco, Brazil. These are clearly different from all other known species of the genus in their external and cranial characters, which are exactly comparable with our specimens collected in Argen-tina. This allows to greatly expand the known geographic distributions for these two species. The addition to Argentina of Myotis lavali with specimens collected in the Yungas ecoregion of Salta Province, and Myotis izecksohni with specimens collected in the Fields and Weedlands ecoregion of Misiones Province, increases the known ecoregions to date for the distribution of the two species.

Lasiurus egregius (Peters, 1870) is an insectivorous bat species known from Central and South America. This species has few confirmed records throughout its distribution. Here we report the first record of L. egregius from the northern coast of Paraná state, southern Brazil. We captured a female individual of L. egregius using an ultrathin mist-net installed over a river knee, at Salto Morato Natural Reserve, municipality of Guaraqueçaba. This is the fourteenth locality with confirmed occurrence of L. egregius, being eight of them in Brazil. The knowledge on the bat fauna in Paraná has been increasing in recent decades, mainly due to the new studies in coast areas of this state. In addition to contributing to the knowledge of the bat fauna from Paraná, the new record of L. egregius reinforces the essential role of the Salto Morato Natural Reserve in conserving bats in the southern portion of the Atlantic Forest.
