Stegana (Steganina) biprotrusa Chen & Aotsuka, 2004: 2783 .

Diagnosis. This species is very similar to S. angulata in the lateral hook-lake projections of gonopods with serrate processes along margins, but can be differentiated from it by having the ventral part of aedeagus unsclerotized, with several serrate processes, and the dorsal part convex on the apical margin ( Chen & Aotsuka 2004, Fig. 7 ).

Specimen examined. Holotype 3 (SCAU, No. 120879), JAPAN: Tomochi, Kumamoto, 17.viii.2002, HW Chen.

Distribution. Japan (Kyushu).
