Dryomimus eliomyoides Kretzoi, 1959: 240 .

Dryomimus aff. eliomyoides – De Bruijn & Van der Meulen 1975: 332-334, pl. 5, figs 8-10, 12, 13.

MATERIAL EXAMINED. — 2 M1-2 (Ms131, 132); (L × W) = 1.43 × 1.62; 1.27 × 1.67.

DESCRIPTION

Medium sized glirid. The anteroloph is disconnected from the protocone as well as from the paracone. The posterior centroloph is strong. The posteroloph is not connected to the metacone but links lingually to the protocone.

REMARKS

The original description of Kretzoi (1959) is rather laconic without designation of a holotype. Thus, it is difficult to make direct comparisons with the Hungarian material. The Muselievo specimens are identical with the respective teeth from Toukobounia I (early Pleistocene, Greece) ( De Bruijn & Van der Meulen 1975). These authors mentioned the great similarity between the Pliocene genus Dryomimus and the Miocene Pseudodryomys De Bruijn, 1965 from Spain. Most probably, this similarity results of a parallel evolution. Therefore, the use of a separate name for the Pliocene genus seems reasonable ( De Bruijn & Van der Meulen 1975). The genera Dryomimus and Myomimus were synonymized by Kowalski (1963). However, the occurrence of a posterior centroloph only is a rather unusual feature for glirids, and consequently this opinion is rejected ( De Bruijn et al. 1970). The material from Muselievo is similar to the molar from Kotlovina (lower and middle layers) ( Topachevsky & Nesin 1989), described as Myomimus cf. eliomyoides . This damaged specimen is possibly a little smaller but the limited material from both localities does not allow further comparisons.
