New records of the bats Histiotus montanus and Molossops neglectus in southeastern Brazil with notes on biology and morphology

Abstract

Distributional and biological data for some bat species in South America are scarce, mainly in non-phyllostomid bats. Herein we provide new records of two rare species of aerial insectivore bats for southeastern Brazil, Histiotus montanus and Molossops neglectus. In addition, we report facial morphological variation in color and new records of ectoparasites for H. montanus. For M. neglectus we performed a Principal Component Analysis (PCA) to check for morphometric variation based on forearm and skull dimensions, the southerly distributed specimens showing slightly smaller measurements than the northern ones.
