CommentDiagnosis. The new species is very similar to Sinonatfix aequifasciata (Barbour) and typically with X marks on the side of body and tail, but with 31- 35 maxillary teeth and 156 - 165 ventrals which obviously differ from S. aequifasciata; the later have 23 - 28 maxillary teeth and 142 - 154 ventrals [from RAO & YANG 1998].
