Diagnosis
ReferenceDiagnosis
C. W. Hibbard and D. Jammot 1971A shrew slightly larger than Smex taylori Hibbard with pigmented teeth. The ramus has the shape of Sorex and the P, as in Soricinae. The entoconid of MI and M, is distinct and joined near the base to the metaconid. The trigonid of M, is reduced and bladelike. The coronoid process is broader at the top than in Sorex and has a well-developed spicule. The articular condyle projects backward and the articular facets are widely separated. The dorsal facet is oval in shape and the ventral facet is widened on the ventral side like that of Blarinella (fide Repenning, 1967, p. 35, fig. 24). The mental foramen is small and below the protoconid of MI. Well-developed anterior and posterior mandibular foramina are located in the same depression.
