Stegana (Steganina) danbaensis sp. nov.

(Figs 1–6)

Diagnosis. This species is related to S. multidentata from Shennonjia, Hubei, but clearly distinguishable from the latter by the epandrium and aedeagus (in S. multidentata: epandrium broadened on posterior margins, more wider than 3/5 high; aedeagus distinctly expanded submedially and with rhombic opening in ventral view).

Description. Male terminalia: Epandrium roundly protruded ventrally, approximately twice as high as wide on posterior margins (Fig. 1). Cercus lacking pubescence (Fig. 2). Surstylus with 8 prensisetae submedially (Fig. 2). Tenth sternite strongly protruded apicolaterally (Fig. 3). Paramere with ca. 5–6 sensilla (Figs 4, 5). Aedeagus with globular projections bearing finely serrated processes basally (Figs 4, 5); nearly oval on opening in ventral view (Fig. 4). Gonopods round apically, not protruded dorsomedially (Fig. 6).
