Diagnosis
ReferenceDiagnosis
G. Storch and Z. Qiu 1983Very small shrew-mole. Dental formula I 3/3, C 1/1, P?3/3, M 3/3; possession of a functional milk-dentition. I1 distinctly enlarged, C1 and P2 not enlarged. Metaconule region of the upper molars not conspicuously expanded and protoconule weak. Posterior ectoflexus of M1 very shallow and premetacrista poorly developed to missing. Lower molars relatively brachyodont; their crista obliqua terminating rather labially and separated by a notch from the protocristid; metastylid lacking; the long entoconid and an entocristid tend to close the talonid basin except for the talonid notch. Lower premolars double-rooted and their protoconid inflated. Relatively strong development of cingula. Slender mandible tapered anteriorly. Humerus adaptively and morphologically as in recent Urotrichini; notch between pectoral ridge and teres tubercle not wide.
