The ventral lobe is specialized in distincta (Text-fig. 133). The hypandrium (Text-fig. 113) is always small, free and situated between ventral bases of gonocoxites. The aedeagus is free, and is basically long and slender in shape, with the phallic part only slightly curved (sole exception: ostentata (Text- fig. 92)). The dorsal apodeme may be totally reduced as in distincta, but is usually 2 to 3 times as wide as proximal part of phallus; only in ostentata (Text-fig. 92) is the dorsal apodeme differently shaped. The ventral and ejaculatory apodemes are usually quite simple and comparatively slender. Tergite 8 is very narrow medially. Sternite 8 is well-developed and of rather variable shape. Female terminalia. With two rows of terminal spines, as is usual in the group; the number varies between 4 and 7. Remarks. The genus Stenopomyia consists of 13 species, and only one of these proves to be described. It is variegata, originally described in Anabarhynchus Macquart, which is a strictly Australian genus. In the Ethiopian region Stenopomyia seems to be restricted to Madagascar, where the late Dr Fred Reiser collected most. Figs 75-86.
