Primary type information:
Primary type material: syntype workers (number not stated, “a number…from a single colony”). Primary type locality: U.S.A.: Texas, Fort Davis (W.M. Wheeler). Primary type depositories: AMNH, MCZC.
Type notes:Pacheco & Mackay, 2013: 296, were unable to find any sytypes. In the original description Wheeler also mentions “a great many specimens” Mexico: Chihuahua, Ojos del Diablo, Santo Domingo Ranch (C.H.T. Townsend), but it is not certain that he intended these should also be regarded as syntypes.
