Trichoura gen. n.

Type species: Trichoura torynopoda sp. n.

Description: Small, brown-yellow, silver pruinose stenopogonine asilids with the following combination of characters: Head ( Fig. 85 ): clearly wider than high in anterior view. Antenna: scape slightly longer than pedicel, segment 3 ca. 1.5 times as long as scape and pedicel combined, style small, conical with terminal spine-like seta. Mystax shiny, white, confined to lower 1 of plane face (only ventral part somewhat protuberant); palpi small, 2-segmented. Thorax: postmetacoxal area membranous; anepimeral bristle absent; I pair scutellar macrosetae (a second pair, much smaller than the first, found only in holotype of krugeri ). Wing ( Fig. 86 ): ca. 3 mm long, transparent, immaculate, uniform microtrichial cover, C extends around entire wing margin (but weakly along hind margin), cells m] and cup closed and stalked. Legs: pulvilli and empodia well developed. Abdomen: ♂ terminalia unrotated; ♂ epandrium with long, silvery, prone setae masking shape (except in proctomeces ); hypandrium small or absent (fused basally with well-developed gonocoxites).

Etymology: Gr. f. trichos - hair + oura - tail: refers to setaceous epandrium.
