( Figs. 15–20 , 27 )

Type material. Holotype: ɗ, deposited in HBUM. Guandu, Chishui, Guizhou Province, China, 23 September 2000, collected by Ren Guo-Dong. Paratypes: 1ɗ, deposited in HBUM. Libo, Guizhou Province, China, 16 August 2000, collected by Shi Fu-Ming; 2 ΨΨ, deposited in HBUM. Dabaitang, Xishui, Guizhou Province, China, 25–29 September 2000, collected by Ren Guo-Dong.

Diagnosis. The new species can be distinguished from A. buricus Schawaller, 1994 , from Nepal by the following characters: body size larger than 10mm; each lateral margin of pronutum irregularly undulated with a sharp fine tooth in front; the protibiae without sexual dimorphism.

Etymology. The specific name is derived from the Latinized word “basi-” and “-latilus”, which refers to the pronotal base broadened and arcuate in the middle than the other species.

Description. Body oval, flat and elongate; body included with labrum, clypeus, 1st and 2nd antennomeres brown, head blackish brown, legs and maxillary palpi light brown, petellae black; dorsum covered with very dense and long pubescence, erect on head, lateral margins of pronotum and of elytra; those on pronotal disc concentrate into the midline, while those on elytra recumbent backwards.

Labrum oblong and projecting with coarse punctures; clypeus convex and coarsely punctate, with straight anterior margin; frontoclypeal suture straight; frons deeply and coarsely punctate, with three smooth carinae bearing from the same point; maxillary palpi with triangularly terminal segments. Antennae robust, reaching base of pronotum; 3rd antennomere about 1.7 times as long as 2nd and slightly longer than the other antennomeres, 3rd to 10th antennomeres cylindrical, last antennomere oval.

Pronotum transverse, about 1.7 times as broad as long, broadest at middle; anterior margin shallowly emarginate, broadened and straight in middle; each lateral margin irregularly undulated with a sharp and fine tooth in front, unbordered; posterior margin widely arcuate in middle; anterior angles angulate, reaching front border of eyes; posterior angles small, acute and pointing outwards; disc convex, coarsely and densely punctate, with irregular carinae between the punctures.

Scutellum triangular, impunctate; elytra about 1.4 times as long as broad, slightly boarder than pronotum; lateral margins finely serrate in basal fourth, shoulders rounded; elytra and pseudopleura with similar punctures as those on pronotum; disc convex. Protibiae straight, gradually broadening towards apex; length ratio of 1st to 5th tarsomeres from base to apex of protarsus and of mesotarsus: 1.2: 0.5: 0.55: 0.25: 1.45 and 1.9: 0.6: 0.5: 0.25: 1.6, while length ratio of 1st to 4th tarsomeres of metatarsus from base to apex: 3.2: 0.9: 0.5: 1.7.

Propleura with fine punctures, and with a small and deep impression at apex; middle of prosternum and Vshaped area of mesosternum densely and coarsely punctate, though the pleura with sparser punctures; metasternum and abdominal sternites finely and densely punctate; metasternum with a round impression between coxae; last abdominal ventrite broadly triangular with rounded apex.

Female. Body size larger than that of male; blackish brown; disc of elytra more convex.

Measurement. Body length: ɗ 10.4–10.7 mm, Ψ 11.4–11.9 mm; width: ɗ 4.4–4.5 mm, Ψ 5.1–5.5 mm.

Distribution. China (Guizhou).
