Description of a tetraploid Tomopterna (Anura: Ranidae) from South Africa

A. Channing, J.P. Bogart

Abstract


A new tetraploid species of sand frog, genus Tomoptema, is described from the eastern Cape. On the basis of
mtDNA sequences, allozymes and advertisement calls, it appears to have arisen as a hybrid between the adjacent
diploid populations of T. de/a/andii and T. cryptotis. The hybridization event is estimated to have occurred
1,5 MYA. Excluding Xenopus. this is the only allotetraploid member of an advanced frog family that is known.
