Diagnosis
ReferenceDiagnosis
A. E. Wood 1936Lower molars tending toward altenation of external and internal
cusps; central cusp apparently absent; posterior arm of protoconoid of m1 extended as crest to lingual margin of tooth; protoconoid free from metaconoid; no hypoconulid on m2, posterior cingulum arising from extemal border of hypoconid.
R. L. Wilson 1968 (Tregomys)A small cricetid with low-cusped, simple molars; m1 with medial anteroconids and subequal anterior cingula; metaconid and protoconid nearly opposite with the posterior side of the latter sloping farther posteriad; m2 sqaurish and realtively large, wider than m1; second lower molar with heavy cingulum on the anterolabial side; masseteric crests low, terminating anteriad at the level of the laterally positioned mental foramen; jaw relatively thin, the depth below m1 greater than the total length of the lower molars; m1 length less than 1.2 mm in well worn specimens; m3 relatively large with greatest transverse width nearly equal to other lower molars; roots on the lower molars long.
