Hypopygium of $ (text-fig. 277). Text-fig. 277.—Side and ventral (dorsal) views of hypopygium of $ Geron parvus n. sp. peculiar in having 4 incisor-like, flattened processes in a row apically on basal part; aedeagus long and curved; central guide with the prong on each side long, slender and curved, the prongs arising some distance away from the U-shaped body of central guide (see figure to left); basal strut narrow and bat-shaped. Types in the South African Museum. Length of body: about 3J mm. Length of wing: about 3J mm.
