Figs. 1–2, 4

Type Locality. China: Qinghai Province, Burhan Budai Shan Mts .

Type Material. Holotype, male labeled ‘‘ China: Qinghai, north slope of Burhan­Budda, canyon Khatu [ca. 20 km S from Barun (36 ° 10 ̍ N, 97 ° 20 ̍ E)], middle July 1901, Kozlov’s expedition [in Russian]’’; 11 male partypes with the same data. Type material deposited in the collection of Zoological Institute (St. Petersburg).

Decription. Holotype, Male (Fig. 1). Body yellowish­brown, shiny, pronotum and elytra semi­transparent. Head densely punctate (punctures separated by 0.5–2.0 times a puncture diameter). Frons not tuberculate; frontoclypeal suture distinct, appears as dark line. Clypeus feebly sinuate at middle, rounded at sides, lighter in color than remaining part of head. Genae rectangular, protruding past eyes. Dorsal surface of head pubescent with minute, barely visible setae. Width of eye in ventral view approximately 2 times as wide as minimum interval between eye and gula. Pronotum yellowish­brown with vague darker maculae on disc, surface coarsely punctate (punctures separated by 1 puncture diameter on disc), pubescent with yellowish barely visible setae. Anterior margin of pronotum not bordered, sides and base finely bordered; hind angles rounded. Lateral margins pubescent with sparse setae. Scutellum trangular, finely punctate, pubescent. Elytra yellowish­brown, shiny, without humeral teeth. Elytral interstices feebly convex, sparsely punctate. Striae fine, coarsely punctate (punctures of striae 2 times wider in diameter than width of striae, separated by 0.5–1.0 times a puncture diameter). Sides and apices of elytra pubescent with short and relatively sparse, but distinctly visible setae. Venter of body yellowish­brown. Disc of metasternum flat, sparsely and coarsely punctate, sparsely pubescent. Legs yellowish­brown. Apical spur of foretibia long and acute, slightly curved downward, located opposite interval between 1 st and 2 nd tibial teeth; spur reaches middle of 2 nd tarsal segment ( Fig. 4 ). Apical spurs of middle tibia slender and acute; lower spur longer than 2/3 length of upper spur. First segment of hind tarsi slightly shorter than 2 following segments together. Adjoining apical setae of hind tibiae of unequal length. Shape of aedeagus typical for the subgenus Bodilus (Fig. 2).

Female. Unknown.

Variability. Body length 5.5–6.3 mm. Some paratypes have pronotum and head almost impubescent, but the absence of setae might be a result of abrasion.

Differential Diagnosis. The species is most similar to A. sordescens Harold but can be separated from it by the lighter coloration of the pronotum ( A. sordescens has larger and more pronounced dark macula on the disc of the pronotum), coarsely punctate and finely pubescent head and pronotum (pronotum and head of A. sordescens smooth, sparsely punctate, punctures separated by 2–4 times a puncture diameter), shape and location of foretibial spur in male (foretibial spur of A. sordescens more slender, located opporsite 1 st tibial tooth and reaching apex of 1 st tarsal segment ( Fig. 5 ), and the shape of the parameres (Figs. 2–3).

Etymology. The species is named in honor of A. N. Kaznakov, noted Russian researcher of central Asia and associate of P. K. Kozlov during his expedition to Mongolia and China in 1899–1901.
