Revision of Genus Trichoprosopon Theobald, 1901 from Fri, 2013-03-15 15:35

The adults of Trichoprosopon are distinguished from other genera in the New World by the following combination of characters: proboscis relatively short, about as long as forefemur; antepronota relatively small and separated; prespiracular setae and mesopostnotal setae present; postprocoxal scales absent; lower mesokatepisternal setae extended above lower edge of mesepimeron; laterotergite with some sparse scales distally. The genus includes some species with setae on the clypeus. Larvae are recognised by the presence of a circular occipital foramen with a distinct collar, maxilla with a maxillary brush and the cardo fused with the base of the palpus, complete hypostomal suture, absence of seta 8-M, and the absence of pecten spines and midventral filaments on the siphon. Larvae have seta 13-T inserted on a common plate with setae 9–12-T, a feature which is otherwise only found in species of Kimia, Isostomyia and Trichoprosopon (Harbach et al., 2007; Campos & Zavortink,
2010). See Sabethini.
