Description – Rhomboid outline. Three main conids: protoconid, metaconid and hypoconid. Three lower developed conids: mesoconid, entoconid and mesolophid. There is a trench between the mesolophid and the entoconid. The anterolophid is more developed, strong and connected to the protoconid and the metaconid. The metalophid is less developed and runs to the middle part of the anterolophid. There is a small basin between the anterolophid and the metalophid. This basin is more developed than the lowest parts of the central basin. The enamel of the central basin is sculptured.

Comments – Other Miopetaurista species: M. goeriachensis (Hofmann, 1893) (MN 5); M. lappi (Mein, 1958) (MN 5); M. gaillardi (Mein, 1970) (MN 7/8); M. neogrivensis (Mein, 1970) (MN 7/8); M. thaleri (Mein, 1970) (MN 14); M. crusafonti (Mein, 1970) (MN 9).

All of them are larger than M. dehmi . Differential diagnosis is given by DE BRUIJN et al. (1980). Up to now M. dehmi was not reported from Hungary, but it is known from the Miocene of Austria ( M. dehmi, Oberdorf, MN 4, DE BRUIJN 1998; M. aff. dehmi, Obergänserndorf and Teiritzberg, MN 5, DAXNER-HÖCK 1998).

Large-sized Miopetaurista sp. is known from the MN7/8 and MN9 faunas of Hungary: Miopetaurista sp. , Rudabánya, MN9, KRETZOI & FEJFAR (2005); Miopetaurista sp. , Felsőtárkány 3/2, MN 7/8 (HÍR unpublished).
