Resumo
A comparative analysis of G-banded karyotypes was performed for seven species of Chiroptera, representing two families (Phyllostomidae and Molossidae). Despite the differences in diploid and fundamental numbers, extensive homologies between six karyotypes were identified: A . planirostris, P. lineatus, S. lilium, G. soricina, P. hastatus (Phyllostomidae) and M. rufus (Molossidae). Robertsonian rearrangements and pericentric inversions account for the differences between the karyotypes of phyllostomid and molossid species. The homologies and rearrangements observed reinforce the monophiletic origin of phyllostomids and the inclusion of species in different subfamilies. In situ hybridization with genomic DNA revealed considerable conservation of the karyotypes, including C. perspicillata, that did not show G-band homologies with the other species analyzed. For the first time, chromosomal evidence is presented of a common origin for Phyllostomidae and Molossidae.
