description: Stegana (Steganina) simola Cui & Chen, sp. nov.
(Figs. 13I, 13J, 62)
Diagnosis. This species is similar to S. (S.) cinereipecta sp. nov. in the shape of male terminalia except aedeagus and subepandrial sclerite (Figs. 30, 62), but can be distinguished from the latter by having the surstylus with numerous minute, serrated processes on outer surface and lacking pubescence (Fig. 62A, B); the aedeagus distally roundly expanded, lacking pubescence (Fig. 62C, D); the subepandrial sclerite slightly vaulted (Fig. 62G).
Description. Male and female: First flagellomere yellow. Clypeus yellow. Mesonotum brown medially, yellow laterally (Fig. 13I). Katepisternum yellowish (Fig. 13J). Scutellum dark brown (Fig. 13I). Halter mostly grey (Fig. 13J). Fore femur with a row of 4 long setae on distal part of posteroventral surface. Abdominal tergites dark brown to black medially, yellow laterally (Fig. 13I, J); sternites yellow, about 1.6 times as wide as long. Male terminalia (Fig. 62): Epandrium with ca. 11 setae on dorsal to posterior portions per side (Fig. 62A). Surstylus with 1 peg-like tooth and numerous setulae near distal margin (Fig. 62A, B). Cercus with much pubescence (Fig. 62A). Hypandrium roundly expanded anteromedially (Fig. 62C, D). Pregonite small, with 2 or 3 sensilla (Fig. 62C, D). Aedeagus with numerous minute, serrated processes distally (Fig. 62C, D). Aedeagal sheath distally with numerous minute, serrated processes (Fig. 62E, F).
