Stegana (Steganina) parvispina sp. nov.

(Figs 41–44)

Diagnosis. This species is similar to S. tentaculifera sp. nov. in the male terminalia, showing distinct dissimilarity in aedeagus, in this species: aedeagus with denser serrated, minute processes on ventral and dorsal surfaces, expressly about 12 irregular rows on ventral surface (Figs 43, 44).

Description. Male terminalia: Epandrium slightly protruded ventrally (Fig. 41). Surstylus with 8 prensisetae submedially (Fig. 41, 42). Tenth sternite slightly protruded basolaterally. Paramere with ca. 4, 5 sensilla (Figs 43, 44). Aedeagus with globular projections bearing finely serrated processes basally, slightly round on opening in ventral view (Figs 43, 44). Gonopods round apically, not protruded dorsomedially.
