Stegana (Steganina) pinguifoliacea View in CoL sp. nov.
( Figs 2D View FIGURE 2 , 7 View FIGURE 7 )
Diagnosis. This species resembles S. longifibula Takada, 1968 in some characters of the body colour patterns ( Fig. 2D View FIGURE 2 ), but can be distinguished by the male terminalia, in this species, the surstylus without minute projections, except acute apically ( Fig. 7A View FIGURE 7 ); aedeagus medially expanded in lateral view, strongly narrowed in ventrally ( Fig. 7B, C View FIGURE 7 ); gonopods nearly vaulted in ventral view ( Fig. 7D View FIGURE 7 ). The minimum interspecific genetic distance to S. longifibula is 4.3%, which is smaller than to other species ( Table 2).
Description. Male: Frons black. First flagellomere greish yellow. Clypeus and palpus yellow. Mesonotum brown to dark brown, with 1 thin, unconspicuous, yellow longitudinal stripe medially, yellowish brown laterally. Katepisternum entirely white. Scutellum black. Femur of foreleg with 4 long erect setae near distal part of posteroventral surface. Abdominal tergites nearly black. Male terminalia ( Fig. 7 View FIGURE 7 ): Epandrium slightly protruded ventrally, with ca. 15 setae on posterior portion per side. Surstylus with numerous setulae distally. Cercus lacking pubescence. Paramere with 2 setulae. Tenth sternite flat dorsolaterally.

Specimens examined. Holotype ♂ ( SCAU, No. 110944), China: Pangquangou, Jiaocheng , Shanxi, 37°04'47''N, 111°30'20''E, altitude 2200m, 30.vii.2016, tree trunk, L Zhu. GoogleMaps
Etymology. A combination of the Latin words: pinguis and foliaceous, reference to the aedeagus medially expanded in lateral view.
