Stegana (Steganina) spatulata View in CoL sp. nov.

( Figs 2E View FIGURE 2 , 8 View FIGURE 8 )

Diagnosis. This species resembles S. nigrithorax Strobl, 1898 in some characters of the colour patterns of body ( Fig. 2E View FIGURE 2 ) and semicircular gonopods ( Fig. 8E View FIGURE 8 ), but can be distinguished by the median flaps of hypandrium ( Hu & Toda, 1994; fused gonopod in Bächli et al., 2004) concave, spoon-like ( Fig. 8E, F View FIGURE 8 ); aedeagus with numerous, serrated, minute processes medially ( Fig. 8C, D View FIGURE 8 ). However, the minimum interspecific genetic distance is 3.1% to S. pililobosa ( Table 2).

Description. Male: Frons brown. First flagellomere yellow on basal 1/4, brown on distal 3/4. Clypeus yellow, slightly brownish medially. Palpus yellow. Katepisternum entirely white. Scutellum brown ( Fig. 2E View FIGURE 2 ). Femur of foreleg with 5 long erect setae near distal part of posteroventral surface. Abdominal tergites entirely dark brown medially, yellowish brown laterally ( Fig. 2E View FIGURE 2 ). Male terminalia ( Fig. 8 View FIGURE 8 ): Epandrium protruded ventrally, with ca. 20 setae on posterior portion per side. Surstylus distally with numerous setulae on inner surface. Cercus lacking pubescence. Tenth sternite with 1 pair of processes submedially. Paramere lacking setula.
