Geographic Distribution. This species is known from the highlands of the Sierra Madre in Guatemala and Mexico (Chiapas) (new country record for Mexico).

Remarks. Three localities in Guatemala were listed in the original description ( Champion 1914: 116), “ Guatemala city [14°37′, −90°30′, 4,850 ft], Dueñas [14°32′, −90°47′, 4,700 ft], Capetillo [14°29′, −90°48′]” (coordinates in brackets are from Selander and Vaurie 1962). Champion (1914: 116) noted that the type series consisted of “ Two males and three females, found mixed with the series named L. canescens by Gorham”, which refers to an initial misidentification of these specimens as Listrus canescens (Mannerheim, 1843) by Gorham (1882).
