Genus Pseudocricetodon Thaler, 1969

Allocricetodon Freudenthal, 1994: 12-15 . — de Bruijn et al. 2003: 61, 62.

TYPE SPECIES. — Pseudocricetodon montalbanensis Ŋaler, 1969 by monotypy.

DIAGNOSIS. — (Combining the original diagnosis of Ŋaler 1969; Vianey-Liaud 1974; Dienemann 1987; de Bruijn et al. 2003; Kalthoff 2006): small to medium-sized cricetid; infra-orbitary foramen hystricomorph, a little pinched dorsally; flat palate (Vianey-Liaud 1974); lower incisors with highly derived enamel (type 7-8, Kalthoff 2006); lophodont molar pattern; main cusps and crests slender and usually straight, rarely irregular, separated by valleys with a flat bottom; wide anterocone on M1 and lingual border of M1 straight or slightly concave.

REMARK

Ŋe most abundant (144 teeth) Cricetidae of Saint- Privat-des-Vieux is assigned to Pseudocricetodon incertus (Schlosser, 1884) . Ŋe cricetid material from BoujacA, in the same sedimentary basin, had also been allocated to this species ( Comte 1985). In his description of the material from the province of Teruel ( Spain), Freudenthal (1994) had erected the genus Allocricetodon for medium-sized forms of the genus Pseudocricetodon Ŋaler, 1969 . Ŋe validity of this new genus is discussed by de Bruijn et al. (2003). In agreement with their conclusions, we consider here the genus Allocricetodon as synonymous to the genus Pseudocricetodon . Two taxa described by Freudenthal (1994) from the Oligo- cene of Mirambueno ( Spain) can be identified in the Alès Basin: Pseudocricetodon (non Allocricetodon ) incertus and Pseudocricetodon (non Allocricetodon ) landroveri Freudenthal, 1994 . We compare the abundant population from Saint-Privat-des-Vieux (MP 26) with that of MIR4C, from Mirambueno (MP 26). We expand the comparison to the cricetids of younger localities: on the one hand, BoujacA (MP 27) in the Alès basin where P. incertus is also recorded and, on the other hand, MIR1 at Mirambueno (Teruel, Spain; MP 27) from which another species – Pseudocricetodon cornelii (Freudenthal, 1994) – has been described (Freudenthal 1994).
