Remarks. Carriker's (1954: 193) illustration of the male genitalia of Brueelia laticeps prasinus appears to have been drawn from a specimen with partially everted genitalia, and is not representative. While we have seen no males of Br. laticeps prasinus, we have seen several male Traihoriella from other host species with partially everted male genitalia, which are indistinguishable from those illustrated by Carriker (1954: fig. 17b). We agree with Cicchino (1983: 301) that the two subspecies are synonymous.
