discussion
Comments: Two synapomorphies allowed the recovery of Brachiotrichomyia: the basal starting point of the bifurcation of the aedeagus, close to the ejaculatory ducts (82 - 0), and feathered setae of the arm of gonocoxite. This subgenus was proposed by Bravo & Araújo (2013) to include some species, such as Opisthotrichomyia and Syntrichomyia, that present four segments on the palpus, with the first two partly fused. These species have gonocoxites projected dorsally and fused basally and an elongated arm with bristles lined on the inner margin. The gonostylus is C-shaped, but can be reduced in some species. The aedeagus is curved and fused at the apex, with an ovoid appearance. It includes species from Costa Rica, Colombia, Brazil and Panama. Other characteristics recovered in the phylogeny include: a long distance from the clypeus to the antennal socket (longer than or as long as the clypeus); wing with the base of M 2 with microtrichia; and male genitalia bearing hypoproct with an acuminated apex.
