( Figs. 7–14 , 26 ) 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. FIGURES 7–14. Anaedus tibiodentatus sp. nov. (%) 7, antenna; 8, pronotum; 9, elytron; 10. mesotibia; 11, metatibia; 12, aedeagus in ventral view; 13, aedeagus in dorsal view; 14, aedeagus in lateral view. 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 . Distribution. China (Yunnan)
