Abstract
There is much confusion concerning the identity of bullfrogs in southe rn Africa. Currently three subspecies are recognized, and introgressio n has been suspected. We demonstrate that in southern Africa there are two species: Pyxicephalus adspersus which has a long call, breeds dur ing the day, and exhibits lek behaviour; Pyxicephalus edulis which is smaller, has a short call, breeds at night and does not exhibit lek be haviour.
