I think the species is entitled to rank in a genus apart from 

 Amphiesnia, the costals not being keeled, and not emarginate. 

 The postoculars are two instead of three, the posterior sublinguals 

 touch three instead of two infralabials, and the 6th infralabial 

 touches only two scales posteriorly.
