| Abstract: | Genetic relationships among eight species of Eptesicus and Pipistrellus were analyzed by use of horizontal starch-gelelectrophoresis. It has been suggested that a 2n = 50 and FN = 48 karyotype defines the genus Eptesicus, and that related forms of differing karyotype should be placed in the genus Pipistrellus. Three species of Eptesicus with 2n = 50 and FN = 48, three species with lower diploid numbers, and two species of Pipistrellus were assayed in this study. The results show that the species of Eptesicus with 2n =50 and FN = 48 form a homogeneous group with high similarity values, despite the included taxa from two continents. Species with lower diploid number show a lesser degree of similarity. |
