[Herpetology • 2008] First record of a natural male hybrid of Bufo (Pseudepidalea) viridis Laurenti, 1768 and Bufo (Bufo) bufo Linneus, 1758 from Austria


Natural male hybrid of Bufo (Pseudepidalea) viridis LAURENTI, 1768
and Bufo (Bufo) bufo LINNEUS, 1758 from Perchtoldsdorf, Austria.

Natural hybridisation of Bufo (Pseudepidalea) viridis LAURENTI, 1768 and Bufo (Bufo) bufo LINNEUS, 1758 was reported occasionally from Germany, the Czech Republic and Italy. Additionaly, hybrids of both species were bred in the laboratory, hybrid spawn, tadpoles and toadlets from these two species are subject to high mortality. The obvious rareness of viable hybrids among Bufo (Pseudepidalea) viridis and Bufo bufo accords with the recent view of the parental species representing different genera (FROST et al. 2006). Nevertheless, there are documented records of adult hybrids in nature
