Description (male, holotype): Length: 13.4 mm; width: 6.5 mm; body elongate ovoid, moderately convex.

Coloration ( Fig. 1 ): Body light brown except for head and legs; head medium brown; anterior margin of clypeus, frontoclypeal suture, ocular canthus and posterolateral portion of vertex blackened; antenna light brown; pronotum with small, vague brown spots near middle of each side; anterior and posterior margin blackened; scutellum with blackened margin; elytra with all margins narrowly blackened except for the suture with a broader blackened area reaching the subsutural interstice; pygidium with a vague, blurry blackish patch near middle of anterior margin; membrane of posterior margin of each abdominal ventrite dark brown; legs predominantly red-brown, with the distal portion of tarsomeres and tibiae blackened, major part of femurs light brown. Head. Clypeus subtrapezoidal, disc transversely punctate, anterior margin rounded, weakly reflexed; frons with deep punctures, which are rugose anteriorly and separated posteriorly. Ratio of interocular width/head width approximately 0.55; antenna long, with pale hairs, antennal club length equals combined length of antennomeres 2-6.

Thorax: Pronotum approximately 1.8 times as wide as long; disc with vague and discontinuous impressed midline; with moderately dense, moderately fine, deep, irregular punctation, somewhat denser and smaller laterally; anterior angles acute and protruding, posterior angles subrectangular, rounded off; sides of pronotum weakly converging anteriad in middle, slightly sinuate in anterior half, subparallel in posterior half; lateral margins with several long setae; anterior marginal line complete, with several short setae near anterior angles which gradually become more distant toward middle; basal marginal line complete and distinct, ending near posterior angles.

Scutellum triangular, with the sides slightly curved; punctures denser and smaller laterally than those at disc; lateral margins smooth; posterior corner sharp.

Elytra approximately 1.5 times longer than wide; elytral surface smooth and shining, striate, strial punctures large and deep; primary striae regular, sulcate, punctures sometimes adjacent to each other; subsutural interstice with irregular punctation anteriorly and a regular secondary stria in the posterior 2/3; second interstice with single secondary stria anteriorly which is irregularly doubled in the posterior 3/4; third interstice with somewhat irregular secondary stria; primary costae and lateral margin with long erect setae, setae of lateral margin distinctly more numerous than those of primary costae; umbones prominent, apico-sutural angle subrectangular, slightly rounded; epipleuron broad near humerus, narrow, ending in posterior third, flat; lateral margins with numerous short yellow setae, sparse in anterior and posterior fourth, dense in elytral mid length.

Ventral thoracic surface with dense, round, large punctures, and dense, moderately long semierect setosity; disc with very fine, sparse punctures, almost glabrous. Pygidium ( Fig. 9 ) triangular, convex; disc with moderately coarse, somewhat transverse punctures, indistinct along anterior margin, partly confluent laterally; posterior marginal line complete; with very sparse long, erect setae.

Legs: Protibia tridentate, apical and middle tooth rather long, basal tooth short, obtuse; with a rather long inner spur; mesotibia weakly fusiform; metatibia very fusiform; outer surface smooth with sparse fine punctures with a single oblique row of rigid spines; with two strong terminal spurs, the upper one 2 times longer than the lower; all tarsi rather long and slender, inner protarsal claw not clefted; metatarsus much longer than metatibia; outer mesotarsal claw clefted, inner mesotarsal claw and metatarsal claws long and simple.

Abdominal ventrites ( Fig. 10 ) with rather sparse, transverse fine punctures in the middle, punctures become gradually denser and larger laterad; with a transverse row of moderately long, yellow setae, interrupted in the middle; with several additional setae laterally; sides carinate.

Aedeagus: parameres simple, short; ventral plate short, hook-shaped in lateral view. As in Figs 3-6 .

Female ( Fig. 2 ): Body slightly stouter; sides of pronotum more strongly curved, subparallel in posterior half; blackish markings much more extended compared to males: pronotum with small black spot near middle of each lateral margin and with two large trapezoidal spots covering the middle of anterior disc, encompassing also the black anterior margin; basal margin of pronotum blackish; major part of central elytral disc and humeral umbones black; protarsus slightly shorter than in male; inner protarsal claw and outer mesotarsal claw apically clefted; erect setae of elytra somewhat longer than in male.

Variability of body size: Male body length: 12.5- 14.3 mm, body width: 5.6-6.7 mm; female body length: 13.4-14.9 mm, body width: 6.1-7.2 mm.

Diagnosis: Anomala xiongi WANG & ZORN , new species can be distinguished from all other Anomala species by conspicuous long erect setae rising from the primary costae of elytra ( Figs 1, 2 ). This new species is most similar to A. fusitibia LIN, 1992 , described from Yunnan and found in Laos and Thailand (see below). But, in addition to the aforementioned setae, A. xiongi also differs from A. fusitibia in the following characters: protibia tridentate, inner protarsal claw not cleft in male ( Fig. 7 ).

Etymology: The new species is named after Zi-Chun Xiong (Yunxian County, Yunnan), who collected the majority of the type material, including the holotype.
