Conventional and G- banded karyotypes are reported for three species of molossid bats from India (Chaerephon plicatus) and Senegal (Ch. pumilus, Mops condylurus). The chromosome diploid number 2n = 48 and the number of chromosomal arms FN = 54 were recorded, similarly as in the previous published reports on karyology of molossid bats from Thailand, East Malaysia, and Africa. A synopsis of karyotypes of bats of the family Molossidae is presented with comments on their chromosomal evolution.
