Keramidomys cf. thaleri Hugeney et Mein, 1968

( Figs 21–22)

Material and measurements (mm) –

Description – P4 – Anteroloph is not developed. The protoloph is strong. Mesoloph is long and connected to the paracone. The longitudinal crest is short, but complete.

M2 – The anteroloph is connected to the central part of the protoloph. The 1st syncline is narrow and closed. The longitudinal crest is ended just behind the protoloph. The mesoloph reaches the labial margin.

m1 – The anterolophid is connected to the labial angle of the protoconid. The 1st synclinid is narrow and closed. The longitudinal crest is ended just behind the protoconid. Mesolophid is long and connected to the metaconid.

Comments – The Keramidomys finds from Litke differ from K. anwilensis Engesser, 1972 in the long mesolophid in m1; from K. carpathicus (Schaub et Zapfe, 1953) in the long mesoloph in P4; from K. mohleri Engesser, 1972 in the smaller measurements; from K. fahlbuschi Qiu, 1996 in the smaller measurements, and in the well developed longitudinal crest in P4; from K. pertesunatoi Hartenberger, 1966 , K. reductus Bolliger, 1992 and K. ermannorum Daxner-Höck et Höck, 2009 in the long mesoloph in the upper molars. The differences between K. thaleri and K. carpathicus are discussed by DAXNER HÖCK (1998), MEIN (2009) and PRIETO (2010). Established classification is possible only in the case of abundant materials.
