Comparative study of the karyotypes of two Egyptian species of bats, Taphozous perforatus and Taphozous nudiventris (Chiroptera: Mammalia).

A detailed karyotypic analysis of two Egyptian species of bats, Taphozous perforatus and Taphozous nudiventris, was made on the basis of conventional data and G-band patterns. No detectable karyotypic difference was found between the two species (2n = 42, F. N. 64). By comparison of G-band patterns, some differences between the two species were seen in the corresponding autosomal pairs. These results are reported for the first time in Egypt.
