Stegana (Steganina) panda sp. nov. (Figs 2C, 6) Diagnosis. This species resembles S. toyaensis Okada & Sidorenko, 1992 in some characters of the male terminalia, but can be distinguished by the mesonotum dark brown, with 1 thin, unconspicuous, yellow longitudinal stripe medially, yellowish brown laterally (Fig. 2C); aedeagus slightly flat apically in ventral view (Fig. 6C, D). The minimum interspecific genetic distance to S. toyaensis is 3.5%, which is smaller than to other species (Table 2). Description. Male: Frons black. First flagellomere yellow on basal 2/3, black on distal 1/3. Clypeus and palpus yellow. Katepisternum entirely white. Scutellum black (Fig. 2C). Femur of foreleg with 4 long erect setae near distal part of posteroventral surface. Abdominal tergites dark brown to black (Fig. 2C). Male terminalia (Fig. 6): Epandrium slightly protruded ventrally, with numerous setae on posterior portion per side. Surstylus with numerous setulae basally. Cercus lacking pubescence. Tenth sternite broadened, with 1 pair of processes submedially. Paramere with 1 setula. Measurements.
