( Figs. 9 View FIGURE 1 – 9 , 15 View FIGURE 10 – 17 , 43–47 View FIGURE 38 – 47 )
Diagnosis. This species can be identified by the following characters: elytral epipleuron is fuscous except both margins black; metaventrite is black except metepisternum fuscous. The male genitalia are diagnostic, especially the penis, with a large hook-like apex.
Description. TL: 2.32–2.56 mm, TW: 1.56–1.72 mm, TH: 1.00– 1.12 mm, TL/TW: 1.48–1.49, PL/PW: 0.50– 0.55, EL/EW: 1.27–1.28.
Body elongate oval, moderately convex, dorsum surface with fine, yellowish white pubescence ( Fig. 15 View FIGURE 10 – 17 ). Head yellow except the base part testaceous. Eyes black. Pronotum yellowish white except the middle part castaneous. Scutellum black. Elytra black with apical 1/6 yellow. Underside, prothoracic hypomeron yellowish white, prosternum fulvous. Mesoventrite, mesepisternum and metepimeron fulvous. Metaventrite black except metepisternum fuscous. Elytral epipleuron fuscous except both margins black.
Head small, 0.57× of pronotal width (HW/PW=0.64/1.12). Punctures on head finer than eye facets, separated by 1–2 diameters, with sparse, thin silvery white pubescence. Eyes small and almost oval, rather coarsely faceted, the widest interocular distance 0.50× of head width. Pronotum 0.72× of elytral width (PW/EW=1.12/1.56), pronotal punctures fine, sparse, 1–4 diameters apart. Surface of elytra with dense, even punctures, separated by 1–2.5 diameters. Prosternal carinae nearly parallel, extending to anterior margin. Prosternal process rectangle, length 2.0 times of width at the base. Abdominal postcoxal lines incomplete, distinctly recurved toward the base of ventrite ( Fig. 43 View FIGURE 38 – 47 ). Area surrounded by the line evenly punctured, relatively narrowly smooth along the line.
Male genitalia: Penis slender, with a well-developed penis capsule ( Fig. 44 View FIGURE 38 – 47 ). Apex of penis curved, forming a large hook ( Fig. 45 View FIGURE 38 – 47 ). Tegmen moderately stout, penis guide slightly narrow at base, converging gradually apically to a pointed tip in ventral view ( Fig. 47 View FIGURE 38 – 47 ). Parameres slightly shorter than penis guide, obliquely truncate on outer distal margin, distal end with a group long and uniform setae; at 2/3 length of parameres inner side, with another group long and uniform hairs ( Fig. 46 View FIGURE 38 – 47 ).
Female genitalia: coxites triangular ( Fig. 9 View FIGURE 1 – 9 ), elongated, about 2.43 times as long as width, tapering to blunt apices, outer and inner margin almost straight, each with several long terminal setae. Spermatheca C-shape, sclerotised.
Types. Holotype male, No.SCAU (E) 13022, Liupan Mountain, Jingyuan, Ningxia, 2300m, 8.VIII.2009, Chen XS Leg. Paratypes: 8 males and 31 females with same data as holotype.
Etymology. The species name is derived from Latin aduncatus referring to a hooked apex of penis.
Distribution. China (Ningxia).
