Description. Male, holotype ( Figs. 1–2 , 10, 15, 20 ). General. Length 13.6 mm , greatest width 9.4 mm ; body elongate ovoid, moderately convex in profile, sub-lustrous. Color. Whole body black, antennae brown. Head. Clypeus sub-trapezoidal, rounded apically, with dense and fine punctures, anterior margin slightly reflexed towards dorsum; clypeofrontal suture extremely weak; frons with dense punctures (sparse at base), the punctures large on disc, small near eyes; interocular distance 0.63 times as wide as the maximum transverse width of head; antenna sparsely covered with yellow hairs, antennal club shorter than antennomeres 2–6. Pronotum. 1.5 times as broad as long, sides expanded in middle; basal part of the sides with short marginal line, basal marginal line not interrupted in the middle, gradually disappearing towards the sides; anterior angles obtuse, posterior angles rounded apically; disc densely covered with punctures but densest at sides; punctures on sides moderately large, gradually smaller towards anterior angles; with a distinct longitudinal smooth area from basal margin to the center of disc; with several long yellow setae along lateral margins. Scutellum. Tongue-shaped, 1.2 times as wide as long; with sparse punctures, punctures only dense basally; posterior margin smooth. Elytra. Approximately 1.17 times as long wide, humeral umbone and apical protuberance prominent and smooth, strial punctures dense, large and deep, forming several moderately deep longitudinal striae, intervals between striae smooth; elytra with large, dense and irregular punctures near base of suture, with small, sparse and rounded punctures close to sides of scutellum; epipleuron starting apical of level of humeral umbone, flat and gradually expanded at basal 1/2, ending at apical 1/4. Pygidium. Subtriangular and moderately convex in profile, with transverse punctures on disc, punctures gradually sparser towards sides; posterior marginal line complete, with brown setae at posterior margin. Abdominal ventrites. Abdominal ventrites 1–3 with fine punctures, the punctures denser in center and at sides; abdominal ventrite 4 with moderately dense transverse punctures, gradually finer from center to sides, denser in center and at sides; abdominal ventrite 5 with dense, fine punctures; abdominal ventrites 1–3 with a transverse rows of sparse, short yellow-brown setae near middle, the setae slightly denser at sides; abdominal ventrite 4 with a row of short yellowish brown setae near apical margin; abdominal ventrite 5 with a row of yellowish brown setae near apex. Legs. All tarsi short, metatarsus rather strong; protarsal inner claw and mesotarsal outer claw cleft, mesotarsal inner and metatarsal inner and outer claws simple and long; protibia bidentate, apical tooth produced and rounded apically, slightly extending beyond apex of first segment of tarsus, basal tooth short and obtuse, inner spur short; mesotibia slightly fusiform, metatibia very strong and fusiform; both mesotibia and metatibia densely covered with yellow hairs at inner sides, with two terminal spurs, the upper one 1.65 times as long as the lower one. Genitalia. As in Figs. 10, 15, 20 . See differential diagnosis. Variability. Body length 12.5–13.6 mm , greatest width 9.1–9.4 mm in males. The holotype and male paratypes show no differences in the shape of the aedeagus. Females ( Figs. 3, 4 , 28 ). Similar to male, but body larger, body length 19.7–20.0 mm, greatest width 9.8–9.9 mm ; antennal club shorter, apical margin of pronotum wider (compare with basal margin); apical tooth of protibia more rounded apically, distinctly extending beyond apex of second segment of tarsus, basal tooth right-angled. Differential diagnosis. Around Himalaya region ( China , India , Bhutan and Myanmar ), four morphologically similar species, Anomala fuscicauda Lin, 1999 , A. merula Arrow, 1917 , A. trochanterica Arrow, 1917 and A. validipes Arrow, 1917 share following characters with the new species: pronotum attenuated anteriorly, causing the anterior somewhat tapered body shape, sides of pronotum expanded in middle, posterior angles rounded apically; all tarsi short, hind legs extremely strong (compare with fore and mid legs). However, A . qiului new species can be distinguished from the four similar species by extremely asymmetric parameres of male genitalia ( Figs. 10–26 ). Except for male genitalia, A. qiului new species differs from A. merula and A. trochanterica by the disc of pronotum with deeper punctures, elytra with large and irregular dense punctures near base of suture, with deeper striae and more convex intervals. Besides, females of A. qiului new species can be distinguished from A. trochanterica by two simple vaginal palps, whereas A. trochanterica with two additional sclerites in the membrane connecting the vaginal palps. Anomala qiului new species differs from A. fuscicauda by body black (brown in A. fuscicauda ), and elytra with several moderately deep and regular longitudinal striae and smooth intervals. Anomala qiului new species differs from A . validipes by body black (reddish brown in A . validipes ). FIGURES 1–9.

Anomala qiului Huang & Wang , new species , holotype (10, 15, 20) and ♀ paratype (28), Anomala fuscicauda Lin, 1999 from Yunnan, China (11, 16, 21), Anomala trochanterica Arrow, 1917 from Sichuan (12, 17, 22, 27), same species from Xizang (13, 18, 23), same species from Yunnan (14, 19, 24), Anomala merula Arrow, 1917 from Assam, India (25, redrawn from a photograph of syntype provided by Carsten Zorn) and Anomala validipes Arrow 1917 from Assam, India (26, captured from Arrow, 1917 ). Etymology. The new species is named after Dr. Lu Qiu (DZṜ) from Southwest University, Chongqing , China , who collected most of type material. Distribution. The new species is only known from Nabang county, Yunnan province , China .
