Diagnosis.

Leucotrichia cultrata is similar to L. hispida and L. viridis . The phallus of all three species shares a similar appearance with the basal loop of the median complex extended on basal supports and a ventral “bulge” to the membranous apex. The mesoventral process of sternum VII can be used to separate the three, being long and digitate in L. cultrata , bearing a tuft of prominent apical setae in L. hispida , and enlarged and apically blunt when viewed ventrally in L. viridis .
