RESUMO

RESUMEN Se presenta el primer registro del proterotérido Neolicaphrium recens Frenguelli, 1921 (Mammalia, Litopterna) en sedimentos del Río Dulce, Departamento Río Hondo, provincia de Santiago del Estero, Argentina. Los rasgos morfológicos y morfométricos observados en el espécimen MPAT073 son coincidentes con los caracteres indicados como diagnósticos de esa especie. Este hallazgo representa el registro más septentrional y occidental reportado hasta el momento para esta especie, y extiende su rango de distribución geográfica conocida. Los datos geológicos disponibles sugieren que el material proviene de una unidad todavía innominada del Pleistoceno.


ABSTRACT The first record of the Neolicaphrium recens Frenguelli, 1921 (Mammalia, Litopterna) from Pleistocene deposits of the Río Dulce, Rio Hondo Department, Santiago del Estero Province, Argentina, is reported. The morphology and morphometry observed in the specimen MPAT073 is coincident with the diagnostic characteristics of that species. This finding represents the northernmost and westernmost record of the species, and thus extends its geographical distribution. Geological data suggest that the material comes from a still unnamed Pleistocene stratigraphic unit.

RESUMO

RESUMEN Siete nuevas especies de Myotis han sido recientemente descriptas en Sud América elevando a 20 el número de especies del género conocidas para la región. Myotis izecksohni y Myotis lavali han sido descriptas recientemente mediante ejemplares procedentes de los Estados de Río de Janeiro, Paraná y Pernambuco, Brasil. Estas especies son claramente diferentes de todas las otras conocidas del género, tanto en sus características externas como craneales, dichos caracteres coinciden exactamente con los de ejemplares encontrados en Argentina. Estos hallazgos permiten extender significativamente la extensión distribucional de las dos especies, e incluir a Myotis lavali en la eco-región de las Yungas en la provincia de Salta, y a Myotis izecksohni en la eco-región de los Campos y Malezales de la provincia de Misiones. Dichas eco-regiones no eran conocidas para la distribución de las nuevas especies.


ABSTRACT 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 Myotis 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 Argentina. 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.

RESUMO

En esta comunicación se da a conocer un caso de leucismo en Eptesicus furinalis en un bosque higrófilo del Iberá, Corrientes, Argentina. El leucismo, referido frecuentemente de modo erróneo como albinismo parcial, consiste en una coloración aberrante, producto de mutaciones genéticas. A diferencia del albinismo, se caracteriza por la pérdida completa de un pigmento en particular o de todos los pigmentos, menos aquellos de partes blandas, donde conservan la coloración típica. El ejemplar colectado, una hembra, presenta una coloración atípica en el pelaje, tanto dorsal como ventralmente, siendo la coloración de los ojos y del patagio la característica para la especie.


In this communication we report a case of leucism in Eptesicus furinalis at a hygrophilus forest in Ibera, Corrientes, Argentina. Leucism, frequently erroneously referred as partial albinism, is an aberrant coloration, as a consequence of genetic mutations. Unlike albinism, which is characterized by the complete loss of a particular pigment or the loss of all pigments, except those of soft tissues, which retain the typical coloration. The specimen collected, a female, has an atypically colored fur, both dorsally and ventrally, but with the characteristic coloration of the species in the eyes and patagium.

RESUMO

En este trabajo se dan a conocer nuevas localidades en la distribución de Platyrrhinus lineatus en las provincias de Corrientes y Misiones, Argentina. Esta especie cuenta con muy pocos registros en el país, todos en la región Mesopotámica. Uno de los registros extiende la distribución de la especie en Argentina aproximadamente 250 km hacia el sur.


The purpose of this study is to communicate new distributional records for Platyrrhinus lineatus in the argentine provinces of Corrientes and Misiones. In Argentina P. lineatus is known only from a few records, all from the Mesopotamic Region. With the information reported here, we extends the distribution of this species almost 250 km south of its previous southernmost known record in the country.

RESUMO

En este trabajo se presenta el primer registro de Micronycteris microtis para la Argentina. El género Micronycteris fue incluido en Argentina hace 10 años, pero su especie no fue determinada. Los ejemplares de M. microtis fueron colectados en la provincia de Salta a más de 1 000 km de la localidad más austral hasta ahora registrada, ubicada en Bolivia. La colecta se realizó en alcantarillas durante el día, compartían el refugio con Anoura caudifer o Glossophaga soricina.


Micronycteris microtis is here included in bat fauna of Argentina. The genus was added to the country 10 years ago, but then was not possible to identify the species due to the scarcity of material. Recently we collected new specimens in Salta Province that allowed us to identify the species as Micronycteris microtis, whose distribution was previously known to be extended south only to Bolivia, at more than 1 000 km from our new locality in Argentina. The specimens were captured with mist nets placed inside culverts during the day; they were sharing shelters with Anoura caudifer or Glossophaga soricina.

RESUMO

Albinism is a phenomenon that has been registered in practically all the living groups of vertebrates. A detailed analysis of the literature about true albinism on bats in the world indicates registers of 67 individuals beloging to 38 different species and eight families. The data are extremely scarce, and for South America, total albinism is known in only four species and two families of bats from Brazil and Venezuela. Here we present a new record of albinism for Sturnira erythromosin Argentina.
