The presence of M3 with mesolophe is remarkable because it never occurs in Allocricetus M3 molars. CONCLUSIONS In Hungary the locality Beremend 15. yielded the richest material of small-sized cricetids of MN unit 16. This material belongs to one species which differs from the Allocricetus genus and situated closer to the Cricetinus of Csarnóta 2.on the basis of the morphological characters, especially the morphology of the anteroconid on ml. The type-species of the genus Cricetinus (Cricetinus variáns Zdansky, 1928) was described from the Middle Pleistocene fauna of Chou-kou-tien, China (The material was revised by Shaohua 1984). The great geographic distance and the age difference make the identification of the finds from Csarnóta uncertain in spite of the morphological similarity. We can clear up this problem only with the direct comparison of the Chinese and Hungarian Cricetinus finds. This uncertainty is increased by the absence of Cricetinus in other European faunae. At this point the question of the first appearence of the genus Allocricetus emerges. In the Hungarian faunal sequence, representatives of this genus appeared in large amount first in Villány 3 (Jánossy 1979, 1986, Hír 1993). In the older faunae their presence is uncertain. One of the uncertain appearances is in the above discussed material of Osztramos 7. The other is in Ivanovce B in Slovakia (Fejfar 1970) where Allocricetus cf. bursae was found together with Kowalskia intermedia. This coexistence is unique. The clearing up of the European evolution of small-sized cricetids after the disappearance of the genus Kowalskia needs further investigations. The finds from Beremend 15 proved the existence of another evolutionary lineage which is independent from Allocricetus. ACKNOWLEDGEMENTS The author would like to express his sincere thanks to Prof. Dénes JÁNOSSY for his permission to study the materials of Csarnóta 4, Beremend 15 and Osztramos 7. and to Prof. László KORDOS for the possibility to study the material of Csarnóta 2.
