Three new records of the rare phenomenon of leucism are presented in three Colombian bats: Carollia brevicauda, Artibeus jamaicensis and Lophostoma silvicolum. The specimen of C. brevicauda was…
Systematics of Vampyressa melissa Thomas, 1926 (Chiroptera: Phyllostomidae), with Descriptions of Two New Species of Vampyressa
A restricted diagnosis for the genus Vampyressa, an emended diagnosis of V. melissa, and descriptions of the two previously unrecognized species related to V.Melissa revealing that V.melissa, as traditionally defined, is a composite of at least three species.

It is shown that neither allometric nor topological change is quantifiable in the pre-detachment ME development of six marsupials and two monotremes, and this challenges the developmental prerequisites of widely cited evolutionary scenarios of definitive mammalian middle ear (DMME) evolution.
Re-examining the hypothesis of allopatric distribution of Myoprocta acouchy and M. pratti (Mammalia: Dasyproctidae) in South America
It is found that both reddish and greenish forms of Myoprocta are sympatric in the Amazon basin of the country, including areas adjoining Ecuador and Peru, and these records apparently refute the hypothesis of allopatry for these species in South America.

A morphological study of 49 specimens from four Colombian collections confirms the presence of three species in Colombia (L. blossevillii, L. cinereus, and L. ega) with distribution in all natural regions that include six of the nine biogeographic provinces.
