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

( Figs 2J View FIGURE 2 , 13 View FIGURE 13 )

Diagnosis. This species resembles S. flavipalpata Chen & Chen in Lu et al. 2011a in the yellow clypeus and palpus, and colour patterns of body ( Fig. 2J View FIGURE 2 ), but can be distinguished by the aedeagus lacking serrated, minute processes basally in lateral view, and with round opening in ventral view ( Fig. 13B, C View FIGURE 13 ). The minimum interspecific genetic distance to S. flavipalpata is 6.9 % ( Table 2).

Description. Male and female. Frons black, with orange yellow stripe medially and band submedially. Frontoorbital plate orange yellow. First flagellomere medially grayish yellow on basal 2/3, black on distal 1/3. Face black on upper 2/3, yellow on lower 1/3. Mesonotum medially brown and with yellow, thin longitudinal stripe, laterally dark brown, with yellow longitudinal stripes and a few patches ( Fig. 2J View FIGURE 2 ). Katepisternum entirely white ( Fig. 2J View FIGURE 2 ). Scutellum brownish yellow medially, dark brown to balck laterally ( Fig. 2J View FIGURE 2 ). Veins R 4+5 and M 1 lacking setae on basal section of dorsal surface. Legs white, brownish knee articulations of fore and hindlegs, and black on distal half of hindleg, distal half of femur and basal half of tibia of midleg. Fore femur distally with 6–8 setae on posteroventral surface. Abdominal 1st to 5th tergites dark brown to black medially, yellow laterally; 6th tergite nearly black. Sternites nearly yellow. Male terminalia ( Fig. 13 View FIGURE 13 A–F): Distal part of 10th sternite diamond-shaped, about 1.85 times as wide as long. Hypandrium anteromedially elongated, as long as width of epandrium and with a few paramedian setae posteroventrally. Gonopods slightly rounded apicoomedially. Aedeagus about 0.5 times as long as aedeagal apodeme. Female terminalia ( Fig. 13 View FIGURE 13 G–I): Epiproct, cercus and hypoproct with dense setae and pubescence. Eighth sternite mostly glabrous, with several setae and pubescence on posterolateral corners.
