( Figs. 29–33 , 44 )

Type material. Holotype: ♂ ( MYNU): Yakou Station, Huanglianshan Mountains , Lvchun County, Yunnan, Chi- na, 102°18’32.90” E, 22°53’36.00” N, alt. 1900 m, 21–23.V.2018, Hao Xu & Jian-Yue Qiu leg. Paratypes: 1♂ ( CFLW) and 2♂♂ ( CMZZ): same data as the holotype ; 3♂ ( CCCC), Fengshuiling Nature Reserve , Jinping County, Honghe, Yunnan, China, alt. 2250m, 11.V.2010, Wen-Hsin Lin leg.

Description. Male, holotype. General. Length: 18.3 mm, greatest width: 9.6 mm; body shape elongate ovoid, moderately convex. Color. The whole body black except antenna dark brown; head, pronotum and elytra with black green luster; pronotum with 6 sub-ovoid yellow patches (two small patches located in center, four big patches located at apex and base of sides, the basal patches bigger than the apical patches, a thin yellow band connecting the basal patch and apical patch forming a black spot near the lateral foveola); prosternum with two yellow patches at apical and basal sides; pygidium with two yellow patches on each side, a big one irregular near base, and a small one sub-ovoid near apex; abdominal sternites 1–3 with a yellow spot on each side. Head. Clypeus sub-trapezoidal, moderately reflexed at anterior margin, with fine, dense and transverse punctures; frons finely rugose at basal half and with fine, dense punctures at apical half; interocular distance equals 0.75 times the maximum transverse head width; antenna with several pale hairs, antennal club shorter than antennomeres 2–6. Pronotum. Approximately 2.0 times as wide as long; disc with fine, dense punctures; anterior angles slightly acute, posterior angles sub-rectangular and rounded; sides curved; basal marginal line weak, nearly disappearing before scutellum. Scutellum. Sub-triangular, 1.3 times as wide as long, with fine, sparse punctures, rounded apically. Elytra. Approximately 1.2 times as long as wide, with fine, sparse punctures, punctures slightly denser between middle and suture, some punctures forming several longitudinal rows; humeral umbones processed; epipleuron narrow at base, flat and gradually expanded at basal 2/3, disappearing at apical 1/3. Pygidium. Sub-triangular and moderately convex, with transverse punctures (moderately dense in center, gradually sparser from center to the sides and disappearing at sides); posterior marginal line complete; disc with brown setae near margin. Abdominal ventrites. With transverse punctures, the punctures gradually denser and smaller from center to sides; apical margins of abdominal ventrites 1–4 smooth; abdominal ventrite 1 with two transverse rows of sparse short brown setae; abdominal ventrites 2–4 with a transverse row of sparse short brown setae near middle; abdominal ventrite 5 with a row of sparse short brown setae near apex (except middle). Legs. All tarsi short and strong, protarsal inner claw and mesotarsal outer claw cleft, metatarsal claws simple; protibia bidentate, apical tooth moderately long (compare to basal tooth) and rounded apically, basal tooth short and acute, inner spur short; mesotibia and metatibia slightly fusiform, with several depressions, metatibia with a row of long brown setae along inner margin, with two strong terminal spurs, the upper one 1.8 times longer than the lower one. Genitalia as in Figs. 31–33 . See differential diagnosis.

Variability. Body length 16.5–18.3 mm, greatest width 9.0– 9.6 mm. The holotype and paratypes show no differences in the shape of the aedeagus.

Female. Unknown.

Differential diagnosis. Anomala xuhaoi new species is very similar to A. flavipunctuata Lin, 1999 and A. flavoguttata Miyake, 2000 in general habitus, body color and male genitalia. Anomala xuhaoi new species can be distinguished from A. flavipunctuata by the following characters: elytra somewhat smoother; the central yellow patches of pronotum shorter ( Figs. 29, 34 ); parameres of male genitalia close to each other in dorsal view (completely separated in A. flavipunctuata ) ( Figs. 31, 36 ), distinctly longer than phallobase and middle piece combined (slightly longer than phallobase and middle piece combined in A. flavipunctuata ), distinctly curved towards venter (curved towards dorsum in A. flavipunctuata ), and strongly convex at base in profile (slightly convex in A. flavipunctuata ) ( Figs. 32, 37 ); the extension of the ventral plate of the aedeagus bifurcate apically, the upper lobe distinctly longer than and the lower lobe in ventral view (trifurcate, the upper lobe nearly as long as both lower lobes in A. flavipunctuata ) ( Figs. 31–33, 36–38 ); Anomala xuhaoi new species is more similar to A. flavoguttata than A. flavipunctuata by elytra somewhat smoother, parameres of male genitalia not curved towards dorsum and extension of the ventral plate of the aedeagus bifurcate apically, but can be separated from A. flavoguttata by the outer apical curvature of elytra not expanded (expanded in A. flavoguttata ) ( Figs. 29, 39 ), parameres close to each other in dorsal view (completely separated in A. flavoguttata ), distinctly curved towards venter (nearly straight in A. flavoguttata ), and strongly convex at base in lateral view (slightly depressed in A. flavoguttata ), each lobe of the bifurcation of the extension of the ventral plate of the aedeagus not bifurcate apically (bifurcate in A. flavoguttata ) ( Figs. 31–33, 41–43 ).

Etymology. The new species is named after Dr. Hao Xu ("浩) from Mianyang Normal University, Sichuan, China, who is one of the collectors of the type series.

Distribution. The new species is so far only known from Lvchun county and Jinping county, Yunnan province, China.
