Type material. Holotype: ɗ, deposited in HBUM. Yingjiang (Alt. 1750 m), Yunnan Province, China, 20 June 1995, collected by Xu Zheng-Hui. Paratypes: 1 Ψ, deposited in HBUM. Mengling (Alt. 2000 m), Yunnan Province, China, 16 April 2002, collected by Song Jin-Xin; 1 Ψ, deposited in IZAS. Heilongtan (Alt. 1950 m), Kunming, Yunnan Province, China, 21–23 June 2000, collected by D. H. Kavanaugh and C. E.Griswold.
Diagnosis. The new species can be distinguished from A. mroczkowskii Kaszab, 1968 by the following characters: antennae without sexual dimorphism; flattened sides of pronotum somewhat upturned.
Etymology. The specific name is derived from the Latinized word “tibio-” in combination with the word “dentatus”; this refers to the ornamentation of male meso- and metatibiae.
Description. Body oval, flat and elongate; brown, head black, antennae, labrum, clypeus and maxillary palpi blackish brown; dorsum covered with white pubescence, erect on head, while those on pronotum and elytra recumbent and bent backwards.
Labrum oblong and projecting, with coarse punctures; clypeus slightly 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 securiform terminal segments. Antennae robust, reaching base of pronotum; 3rd antennomere as long as 4th and slightly longer than 5th to 10th antennomeres, about 2.5 times as long as 2nd antennomere; last antennomere oval, with cuspidal apex, other antennomeres cylindrical.
Pronotum transverse, about 2.2 times as broad as long, broadest at middle; anterior margin shallowly emarginate, broadened and almost straight in middle; lateral margins evenly and strongly arcuate laterad, distinctly sinuous just before basal angles, with very narrow border; flattened sides slightly upturned; posterior margin broadly and slightly rounded; anterior angles obtusely rounded and reaching front border of eyes; posterior angles acute, pointing outwards and somewhat upturned; disc convex, coarsely and densely punctate, bearing irregular carinae between the punctures; midline evident.
Scutellum triangular and without punctures; elytra about 1.6 times as long as broad, somewhat boarder than pronotum; lateral margins finely serrate in basal fourth, rounded at shoulders; elytra and pseudopleura with similar punctures as those on pronotum. Protibiae straight, gradually broadening towards apex; meso- and metatibiae with fine serrated teeth in apical half; length ratio of 1st to 5th tarsomeres from base to apex of protarsus and of mesotarsus: 0.8: 0.5: 0.45: 0.2: 0.95 and 1.3: 0.6: 0.4: 0.2: 1.3, while length ratio of 1st to 4th tarsomeres of metatarsus from base to apex: 2.5: 0.8: 0.6: 0.9.
Propleura smooth, with a few punctures, prosternum coarsely punctate in middle; lateral margins of meso- and metasternum and pleura with dense and coarse punctures, median parts of them and abdominal sternites finely punctate; metasternum with a round and smooth impression between coxae; last abdominal ventrite broadly triangular with pointed apex.
Female. Body size larger than that of male; black to blackish brown; inner margins of meso-and metatibiae without teeth.
Measurements. Body length: ɗ 8.0 mm, Ψ 9.7–10.0 mm; width: ɗ 3.7 mm, Ψ 4.0– 4.7 mm.
