Bufotes viridis (LAURENTI, 1768) species group

Text-fig. 5e

M a t e r i a l. One ilium, EUNHM PV-13227,

Nasrettinhoca 2, early Pliocene, MN 14.

D e s c r i p t i o n. The specimen is represented by a fragmentary right ilium with complete acetabular portion and posterior part of the iliac shaft. The iliac shaft is thick and rod-like. It is devoid of a dorsal crest (= crista dorsalis) as in all bufonids. The dorsal tubercle (= tuber superior) is high and symmetrical. It is not divided into two tubercles as occurs in some taxa of the B. viridis species group. The preacetabular fossa (= fossa praeacetabularis) is well-developed. The pars ascendens and descendens are very narrow.

R e m a r k s. The specimen is assigned to Bufonidae and the B. viridis species group based on the absence of a dorsal crest, presence of a distinct dorsal tubercle, and presence of a well-developed preacetabular fossa. The Bufo viridis species group (or Bufo viridis sensu lato) is widely distributed extending from Central Europe to Central Asia. The green toads from the Balkans, Anatolia and Caucasus are assigned to B. variabilis (PALLAS, 1769) (see Stöck et al. 2006, 2008). But there are no osteological characters allowing the specific identification of B. variabilis and other recognized species of the B. viridis species group. Due to this situation and the fragmentary material from Nasrettinhoca 2, we assign the specimen to the Bufotes viridis species group.
