Stegana (Steganina) izu Sidorenko, 1997b: 167 View in CoL .

Remarks. The male specimens from Ryukyu Islands, Japan slightly differ from the type materials from Izu Islands , Japan in the distal shape of aedeagus and aedeagal sheath (as figs. 4–7 in Sidorenko 1997b, Fig. 24C–F View FIGURE 24 ). They were conservatively identified as conspecific.

Description. Female terminalia (Fig. 24H–J): Epiproct with several setae, lacking pubescence (Fig. 24H). Cercus with numerous setae and much pubescence (Fig. 24H). Eighth sternite about 1.5 times as wide as long, glabrous on basal 2/3, with some setae near posterior margin ( Fig. 24I View FIGURE 24 ). Hypoproct with numerous setae and much pubescence ( Fig. 24J View FIGURE 24 ).
