Range Description

This Mexican endemic species is currently known from the type locality which is 4 km west of El Palmito on Highway 40, in Municipio Concordia, in the state of Sinaloa (23°33’14.2’’ N, 105°50’47.2’’ W), at 2,000 m asl, and from 10 km further down the highway just across the border in the state of Durango. This region is not well surveyed and it is more than likely that the range of the species is much wider than is currently known.
