Type material. Female holotype from Palo Bolero, 1200 m , Morelos [99º6.0'W, 18º40.8'N], Mexico, Aug. 14, 1955, B. Malkin coll. and female paratype from 10 km south of Temixco [99º13.8'W, 18º51.0'N], Morelos, Mexico, Jul. 14, 1956, W. Gertsch & V. Roth coll., both deposited in AMNH.

Etymology. The specific name is a noun in apposition taken from the type locality.
