Northern distributional extensions of Peropteryx leucoptera and Peropteryx pallidoptera (Chiroptera: Emballonuridae) from Vichada, Colombia

Abstract

The White-winged Dog-like Bat (Peropteryx leucoptera) and the Pale-winged Dog-like Bat (Peropteryx pallidoptera) are distinguished from the other emballonurid bats because they have white or translucent wings. Their distribution and biology are poorly known due to they are no captured in traditional bat inventories using mist nets. In this contribution, we extend the known distribution of P. leucoptera 260 km NE and P. pallidoptera 290 km NE. Our records are from three specimens collected in a mammal assessment at the riparian corridor of the river Meta in the Vichada department. This locality is the northern limit of the distributional range of both species. We highlight the need to continue the fieldwork on mammals inventories with specimen collections through the Colombian Llanos. We call attention to the importance of horizontal rotten logs as roost of P. leucoptera and other little known neotropical bats.
