If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
G. Storch and Z. Qiu 2004First 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.
