Diagnosis.

Leucotrichia fairchildi is currently the only member of the L. pictipes Group recorded in Panama. Leucotrichia pictipes known distribution includes Mexico, while L. imitator Flint, 1970 and L. sarita Ross, 1944 have been recorded in nearby Costa Rica. All species in this group bear only two ocelli and share similar shapes to the inferior appendage and sternum VII, when viewed laterally. The modified basal antennal segments and setiferous production on the dorsum of the head can be used to easily separate L. fairchildi from each of the three other species.

Remarks.

A pharate female in a pupal case was identified by Botosaneanu and Alkins-Koo (1993) as " Leucotrichiini -case 2". Subsequently, Flint (1996) associated this female with L. fairchildi , in addition to collecting adult material from Trinidad and Venezuela.
