Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. de Lapparent de Broin 2004 | Narrowed axillary notches; the epi / hyoentoplastral hinge coincides exactly with the gularointergular / humeral sulcus; most narrowed nuchal for the family, anteriorly and posteriorly; absence of neurals except the first one, pentagonal, sometimes present in each species; absence of the first suprapygal; robust and small thoracic rib 1 [see in 13], reduced to its more medial part, short but rather wide and abruptly diverging from the rib 2. Based on S. laosiana n. sp., with respect to Fergane-
mys verzilini [17,21]: small foramen stapediotemporale; more narrowed prootic; smaller orbits; otic trochlear process closer to the postorbitary; less sinuous transversal prefrontofrontal suture. |
