Abstract
Myotis is the most speciose genus of mammals in the world and recent taxonomic revisions have revealed an impressive diversity of species in South America. Even so, the phenotypic conservatism of some taxa makes taxonomic delimitation difficult. We perform a taxonomic review of Myotis from Argentina based on qualitative and quantitative morphological characters. Our results confirm the occurrence of 12 species (M. albescens, M. chiloensis, M. dinellii, M. izecksohni, M. keaysi, M. lavali, M. levis, M. nigricans, M. oxyotus, M. riparius, M. ruber, and M. cf. simus) and revealed an additional new species for the Yungas Forest. The new species is small to medium (forearm length ~ 35 mm) and can be distinguished from its congeners by a set of characters that includes forearm length, cranial measurements, discrete craniodental characters, and fur color. This review does not exhaust the need for new systematic studies with Argentinean Myotis, considering the possibility of occurrence of new species and the great morphological variation found for some complex taxa.

Abstract
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.

Abstract
La actualización de la lista de especies presentes en un país es una tarea continua que llena vacíos de información y apoya la toma de decisiones. En los últimos cinco años, ha habido un aumento del número de especies de mamíferos descritas como nuevas en Colombia, así como primeros registros y cambios taxonómicos. Con el fin de actualizar la información de las especies de mamíferos de Colombia, realizamos una revisión exhaustiva de los cambios taxonómicos de las 528 especies registradas en listas previas. Agregamos nuevas especies descritas, así como nuevos registros de especies ya descritas. Discutimos especies cuya presencia ha sido sugerida recientemente en Colombia, pero que no es respaldada por especímenes de museo. La lista actual de mamíferos en Colombia tiene 543 especies, con cuatro descritas en el último año. Esperamos que la lista sea una herramienta apoyar las necesidades de investigación, en especial las extensiones de distribución, los problemas taxonómicos y la conservación de los mamíferos del país. Finalmente, recomendamos que las actualizaciones de la lista sigan estándares nacionales e internacionales como Darwin Core, utilizado por el Repositorio de Información Global sobre Biodiversidad - GBIF, y el Sistema de Información sobre Biodiversidad de Colombia – SiB.

Abstract
Abstract
The genus Myotis comprises a diverse group of vespertilionid bats with worldwide distribution. Twenty-eight Neotropical species are currently recognized. In this study, we evaluate molecular and morphological variation in the M. keaysi complex, a high elevation clade of Neotropical myotine bats characterized by complex taxonomy and high morphological variation. A phylogeny inferred with cytochrome-b sequences recovered two clades composed of samples traditionally assigned to M. keaysi, with 9% of genetic divergence between them. These clades were also suggested as putative distinct species by molecular species delimitation methods. Qualitative and quantitative morphological analyses indicated a phenotypic discontinuity between specimens from central Andes (including the holotype of M. keaysi) and western lowlands of Ecuador, showing strong congruence between molecular and morphological approaches. We therefore describe a new species for the Tumbes-Choco-Magdalena region, documenting their external and cranial diagnostic characters by comparing them with other Neotropical species. In addition, we provide an emended diagnosis for our new concept of M. keaysi.

Abstract
Abstract
The genus Myotis comprises a diverse group of vesper bats with worldwide distribution. Twenty-eight neotropical species are currently recognized. Based on a morphological approach, we describe a new species of Myotis from the Uruguayan Pampas grasslands, an ecoregion under high anthropogenic pressure with a largely unknown bat fauna. Qualitative and quantitative morphological analyses support the recognition of the new species and we present a set of external and cranial diagnostic characters by comparing them with other neotropical Myotis species. The new species reassembles Myotis riparius, but can be distinguished by a set of qualitative and quantitative morphological traits, including its clearly bicolored dorsal fur, tricolored ventral fur, a pelage on the dorsal surface of uropatagium, sagittal crest lower, braincase lower in lateral view and overall smaller size.
