Ensiferella sabroskyi Nartshuk , male. 19. epandrium, ventral view; 20. epandrium, lateral view; 21. hypandrium and phallic complex, ventral view; 22. hypandrium and phallic complex, lateral view. Scale bar = 0.1mm . Male genitalia(Figs. 19–22): Epandrium short tubular, weakly sclerotized, brown with long brown setulae, with 2 band-like sclerites along posterodorsal notch. Surstylus basally broad with spinous processes, distally narrowed, attached to epandrium anteroventrally, with short setulae. Cercus large, nearly square with 6 pairs of setulae. Gonites arranged in a row; postgonite distinctly incurved apically with pointed apex, with some sensory setulae, basally narrowed; pregonite as long as postgonite, basally broad and round, distally pointed; basiphallus cylindrical; distiphallus long, cylindrical, beyond lower margin of hypandrium; phallapodeme short, reached basal 1/6 of postgonite, with basal stalk broad in lateral view. Hypandrium narrowed. Material examined. CHINA : Yunnan : 1 3, Mengla, 5.V. 2005 , Xiaoshuan Bai; 1 3, Mengla, 6. VIII. 2010 , Wenliang Li; 1 3, Mengla, 8. VIII. 2010 , Hui Yu. All specimens were stored in 75% ethanol. Distribution. China (Yunnan); Vietnam (Shonla). Remarks. The male is described with figurations of male genitalia for the first time. The type specimen of E. sabroskyi is a female. The specimen of E. sabroskyi agrees well with material from China except that in the latter postpronotum yellow with a small brown spot; scutum brown with 3 broad black longitudinal stripes. These may represent intraspecific variation or these specimens may be a distinct species. Examination of additional specimens would be required to resolve this question.
