Leucism in Sebas short-tailed bat, Carollia perspicillata (Linnaeus, 1758), from a rock shelter in northeastern Brazil

A female specimen was captured in a rock shelter located within a anthropogenic fragment of Atlantic Forest in the northeastern Brazilian state of Sergipe. This specimen revealed leucism restricted to the pelage of the body, which was completely white, whereas the eyes, wings, legs, ears, snout, and nasal leaf were all coloured normally. The female was apparently well integrated into the group, ostensibly healthy, of normal size and carrying a late-term fetus.

First record of partial albinism (leucism) in Carollia perspicillata (Phyllostomidae) in Ecuador

One individual of Carollia perspicillata showing partial albinism (leucism) is reported in this study. The specimen was captured in a mist net at Estero Inés, San Francisco River Basin, located in the southwestern of Esmeraldas Province, northwestern Ecuador. The adult, female, presents a high degree of albinism over most of the body. This is the first report of leucism in Ecuador not only for bats, but for all small mammals.

Análisis morfológico y morfométrico de Carollia colombiana Cuartas et al. 2001 y C. monohernandezi Muñoz et al. 2004 (Phyllostomidae: Carollinae) en Colombia / Morphological and morphometric analyses of Carollia colombiana Cuartas et al. 2001 and C. monohernandezi Munoz et al. 2004 (Phyllostomidae: Carollinae) in Colombia

Se revisa la taxonomía de Carollia colombiana y C. monohernandezi en Colombia usando análisis morfológicos y morfométricos. Los resultados indican que C. colombiana no presenta diferencias significativas a nivel morfológico o morfométrico al compararlo con C. brevicauda. De otro lado, el holotipo de C. monohernandezi presenta caracteres morfológicos discretos que la separan de las demás especies reconocidas en el género. Diecisiete paratipos de C. monohernandezi son re-identificados como C. brevicauda o como C. perspicillata. Los resultados presentados aquí soportan el reconocimiento de C. monohernandezi como una especie válida y sugieren el reconocimiento de C. colombiana como un sinónimo menor de C. brevicauda. La diversidad del género Carollia en Colombia, de acuerdo a nuestros resultados, es de cuatro especies.

We reviewed the taxonomy of Carollia colombiana y C. monohernandezi in Colombia using morphological and morphometric analyses. The results indicate that C. colombiana does not exhibit significant differences when compared to C. brevicauda. On the other hand, the holotype of C. monohernandezi exhibits discrete morphological characters that distinguish this species from the remaining species in the genus. Seventeen paratypes of C. monohernandezi are re-identified as C. brevicauda and C. perspicillata. Our analyses support the status of C. monohernandezi as a valid species and suggest that C. colombiana should be recognized as a junior synonym of C. brevicauda. The diversity of the genus Carollia in Colombia, according to our results, is of four species.

O uso de RFLP na filogeografia de Carollia perspicillata, Linnaeus 1758 (Chiroptera: Phyllostomidae)

Molecular data has been used succesfully in evolutionary biology, allowing accurate estimates forgenetic diversity within and between populations in a species, identify clades and test biogeographic hypothesis.The short-tailed fruit bat Carollia perspicillata belongs to the subfamily Carollinae (Chiroptera: Phyllostomidae)and is distributed from Mexico to Brazil, Paraguay and Argentina. In a previous study using mtDNA cytochromeb gene sequences, two haplotype groups were identified in Latin America for C. perspicillata. One of these groups, identified as Clade B, was distributed along the Brazlian Atlantic Forest, while the other group, Clade A,occurred from Central America and the Guyanas to Northeastern Brazil, where it co-occurred in full sympatry forsome locaties in the Northern portion of the Atlantic Forest. The objective of this study was to determine if RFLPidentifies the same clades previously identified from cytochrome b sequences, and if the individuals from theAmazon region, which had not been sampled in the previous study, would fit within one of these clades. Theresults show that Amazonian samples belong to both clades and suggests that the Amazon region might be agradient or cline with a transition from Clade A (Northern) and Clade B (Coastal and Southern), that developedperhaps due to a break in gene flow due to geographic isolation.
