Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Storch and Z. Qiu 2004 | First and second upper and lower molars resemble those of Wilsonosorex Martin, 1978. Differs from Wilsonosorex by its undivided mesostyle (well-divided in Wilsonosorex), crest-like and Y-shaped metaconule (a high pinted cusp in Wilsonosorex), and weaker paraconule of M1-2 (strong and doubled in Wilsonosorex); discontinuous ectocingulid below protoconid and hypoconid (below protoconid only in Wilsonosorex), and very sharp, laterally compressed entoconid of m1-2 (less crest-like in Wilsonosorex). Small size as in W. bateslandensis. Additional diagnostic features include rather small first upper and lower incisors. Differs from all other heterosoricine genera in having well-developed conules on upper molares and reduced ectocingulids on lowers. Postcranial skeleton essentially soricid-like. Differs from other subfamilies, as far as known, by unfused tibia and fibula. |
