(Fig. 4K–M, 8)  
 Type material. Holotype: ♂ ” China, 1000–1300 m, Shaanxi, Qinling mts., Xunyangba (6 km E), 23.v.–13.vi.1998 J.H. Marshall leg.” (MMBC via TICB).   
 Holotype description. Length: 6.3 mm, length of elytra: 3.9 mm, width: 3.3 mm. Body oblong; legs black; dorsal surface dull; head and pronotum with long, dense, erect setae; pilosity on elytra sparse; brown pilosity on head, pronotum, elytra. Head: Labroclypeus transverse, widest medially with lateral margins moderately convex, convergent anteriorly and toward base; anterior angles strongly rounded; lateral border and ocular canthus producing distinct, blunt angle; anterior and lateral margin strongly reflexed; anterior margin shallowly sinuate medially; surface almost flat medially, moderately shiny with double punctation; fine glabrous punctures mixed with coarse, dense punctures each bearing a long, erect seta. Frontoclypeal suture distinct; weakly curved, slightly elevated; smooth area anterior to eye as wide as long. Ocular canthus moderately long, slender; finely, densely punctate; densely setose. Frons with double punctation; fine, glabrous punctures mixed with coarse, moderately dense punctures each bearing a long, erect seta; basal punctation less dense, predominantly fine, almost glabrous. Eyes small, ratio of diameter / interocular width: 0.47. Antenna with ten antennomeres, brown; club with five equal in length antennomeres; club 2.5 times as long as remaining antennomeres combined, reflexed. Prementum weakly elevated, transversely carinate; distinctly concave apical to elevation. Pronotum: widest adjacent to base; lateral margins in posterior half moderately convex and convergent anteriorly, in anterior half strongly convex and convergent; anterior angles not produced, strongly rounded; posterior angles moderately rounded; anterior margin medially weakly convex with distinct, fine marginal line; basal margin medially without fine marginal line. Pronotal surface with dense, double punctation; fine, glabrous punctures mixed with large punctures bearing each a moderately long, erect seta. Anterior and lateral borders setose; basal margin of hypomeron not produced ventrally, not transversely sulcate anterior to base. Scutellum: moderately long; apex moderately sharp; with fine, sparse punctures; minute setae present in punctures. Elytra: oblong, widest medially; striae indistinctly impressed, finely densely punctate; intervals weakly convex with fine, moderately dense punctures; punctures on odd intervals with long, erect setae which are longer, denser anteriorly; sutural interval with robust, long single seta. Epipleural edge fine, ending at strongly convex external apical angle of elytra; epipleura densely setose, strongly curved in anterior third of elytra; apical border chitinous, without short microtrichomes. Venter: Ventral surface dull with fine, dense punctures. Metasternum with dense, long setae; setae partially appressed, partially erect. Metacoxa glabrous near articulation of the leg; elsewhere with fine, long appressed setae. Abdominal sternites with indistinct transverse row of coarse punctures bearing thick setae between fine, dense punctation; all sternites with fine, long setae; tegument of abdominal sternites (60x magnification) with fine polygonal mesh pattern formed by microtrichomes; penultimate sternite at midline with longitudinally impressed line. Mesosternum between mesocoxae narrow, narrower than mesofemur, with irregularly scattered, strong setae. Ratio of length of metepisternum / metacoxa: 1 / 1.56. Pygidium at apex strongly convex; posteriorly shiny; with fine, dense punctures bearing fine, moderately long setae; without smooth midline. Legs: slender with shiny surface. Femora with two longitudinal rows of setae; finely, densely punctate and setose; anterior edge of metafemur acute, lacking adjacent serrated line; posterior margin weakly convex with a few fine setae medially; ventral posterior margin weakly widened in apical half; posterior margin smooth ventrally and dorsally. Metatibia moderately slender, long, widest at apex; ratio width / length: 1 / 3.2; dorsally sharply margined; dorsal edge serrate, with two groups of spines, basal group at one third, apical group at two thirds of metatibial length, basally with a few single spines in punctures; lateral face longitudinally convex with dense, fine punctures; ventral edge serrated, with four strong, long, equally spaced spines; medial face finely punctate, apex sharply truncate interiorly near tarsal articulation. Tarsomeres dorsally glabrous, coarsely punctate; ventrally with sparse, short setae; metatarsomeres dorsally without longitudinal impressions, ventrally with strongly serrated ridge adjacent to strong longitudinal carina, laterally with strong longitudinal carina; first metatarsomere slightly shorter than following two tarsomeres combined, one third of length longer than upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical; basal tooth of inner protarsal claw widened, truncate apically. Aedeagus: Fig. 4K–M.   
 Diagnosis. This species differs from the similar A. huashanica by the right paramere (Fig. 4K–M)which is straight in A. qinlingensis and not curved externally as in A. huashanica and the medial margin of its basal lobe is weakly reflexed and bears a secondary small lobe distally, the left lateral apophysis of phallobase is narrower in lateral view.   
 Etymology. The new species is named after Qinling mountains, where it occurs.
