Diagnosis

G. Storch and D. Dashzeveg 1997More transverse upper molars, with small hypocones, and propotionally wider lower molars than in Galericinae. Trigonid of m1 shorter than wide, though the paracristid froms a high shearing crest. Hypoconulid of m1-2 strongly reduced or absent; if present, placed very close to the entoconid; the hypoconulid of m3 projects posteriorly. Wide postcingulids on m1-2, ending at the hypoconulid region. Anterior dentition specialize: canines small, premolar series anterior to p3 shortened, p2 short and one-rooted, p1 short and one-rooted or absent. p4 with well-developed trigonid and reduced unicuspid talonid. P3 of subtrigonid type, double-rooted. Main cusps of p3-4 rather high and piercing. Critid obliqua of m1-3 low and buccal in position, joining the trigonid below the apex of the protoconid. Mental foramen associated with a depressed area on the lateral face of the lower jaw or with a groove directed anterodordad from the foramen.
