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.
