Holotype description. Length: 5.8 mm, length of elytra: 3.6 mm, width: 3.3 mm. Body oblong; legs black; elytra, one basomedial and two lateral spots on pronotum reddish brown; dorsal surface dull; head and pronotum with long, dense, erect, brown setae; pilosity on elytra sparse, brown. Head: Labroclypeus transverse, widest medially, with lateral margins moderately convex and convergent anteriorly and toward base; anterior angles strongly rounded; lateral border and ocular canthus producing a distinct blunt angle; anterior and lateral margin strongly reflexed; anterior margin shallowly sinuate medially; surface almost flat medially, moderately shiny with double punctation; coarse, dense punctures mixed with fine glabrous punctures; coarse punctures bearing each a long, erect seta. Frontoclypeal suture distinct; weakly curved and 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; coarse, moderately dense punctures mixed with fine glabrous punctures; coarse punctures each bearing a long, erect seta; basal punctation less dense, predominantly fine, almost glabrous. Eyes small, ratio of diameter / interocular width: 0.44. Antenna with ten antennomeres, brown; club with five equal in length antennomeres; club 2.5 times as long as the remaining antennomeres combined, reflexed. Prementum weakly elevated, transversely carinate; distinctly concave apical to elevation. Pronotum: widest adjacent to base; lateral margins in basal half moderately convex and convergent anteriorly, in apical half strongly convex and convergent; anterior angles not produced, strongly rounded; posterior angles moderately rounded; anterior margin weakly convex medially with distinct, fine marginal line; basal margin medially without fine marginal line. Pronotal surface with dense, double punctation; punctures fine, glabrous, mixed with large punctures, each bearing a moderately long, erect seta; large punctures lacking on centre of disc. 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; punctures with minute setae. Elytra: oblong, widest medially; striae indistinctly impressed, finely densely punctate; intervals distinctly convex with fine punctures along the striae; punctures with long, erect setae on odd intervals; 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 except with fine, long, appressed setae near articulation of leg. 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 / 1.6. Pygidium 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 fine, densely punctate setae; 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 / 3.6; apically sharply margined, apical edge serrate; with two groups of spines, basal group at one third, apical one 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, length one third longer than upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical; basal tooth of inner protarsal claw widened, truncate apically. Aedeagus: Fig. 3K–M .

Intraspecific variation. Length: 5.4–6.7 mm, length of elytra: 3.3–4.0 mm, width: 3.0– 3.7 mm. Coloration varies strongly: body and legs sometimes entirely black, entirely reddish brown, reddish brown with apex of elytra dark, or reddish brown with pronotum dark and apex of elytra dark. ♀: antennal club with three antennomeres and distinctly shorter than the remaining antennomeres combined; eyes equal in size to that of male.

Diagnosis. The new species differs from the similar A. kozlovi by the distinctly shallower sinuate anterior border of labroclypeus, the more strongly produced anterior angles of pronotum, and by the shape of parameres ( Fig. 3K–M ). The right paramere is externally concavely curved and posseses a longer basal lobe, which is directed distally; the medial margin is not reflexed as in A. kozlovi ; and the left paramere is abruptly narrowed before apex in lateral view.

Etymology. The new species is named after the type locality, Hua Shan.
