Stegana (Steganina) glabra sp. nov.

(Figs 14–20)

Diagnosis. This species is related to S. ctenaria from Japan, but clearly distinguishable from the latter by the tenth sternite squarely protruded and bearing pubescence apically (Fig. 16).

Description. Male terminalia: Epandrium roundly protruded ventrally (Fig. 14). Cercus lacking pubescence (Fig. 14). Surstylus with 7 prensisetae submedially (Fig. 15). Paramere with ca. 5 sensilla (Figs 17, 18). Aedeagus with globular projections bearing finely serrated processes basally, nearly oval on opening in ventral view, protruded apically (Figs 17, 18). Gonopods round apically, not protruded dorsomedially (Figs 19, 20).
