 TYPE MATERIAL. Holotype: ♂ (MYNU), China: Yunnan Province / Xishuangbanna / Menghai County / IV– V. 2023, local leg. // HOLOTYPE // Anomala menghaiensis / Wang det. 2023; Paratypes: 2 ♂, 1 ♀ (MYNU): same data as holotype.   
DESCRIPTION. Holotype, male. Body length: 18.4 mm, width: 9.0 mm. Body elongate ovoid, rather convex in profile.  
Coloration. Whole body color dark brown with bronze metallic lustre and green reflections except for antennal club brown. Each elytron with four yellow spots from sides to sutural, all spots located separately on costal interval 1 (sutural interval) to costal interval 4, connection of all spots on elytra forming M-shaped.  
Head. Clypeus approximatively semicircular, width slightly more than twice as length, anterior margin moderately reflexed, disc slightly raised, surface densely rugo-punctate. Fronto-clypeal suture slightly arcuate backward. Frons densely punctate, punctures coalescent posterior of fronto-clypeal suture and area close to eyes, interocular distance equals 0.63 times the maximum transverse head width. Vertex with dense, rounded, identifiable punctures. Antennal club longer than antennomeres 1–6 combined.  
Pronotum widely trapezoidal, approximately 1.86 times wider than long in dorsal view, with two rounded impressions before middle on each side and before posterior angle. Sides weakly convergent before middle, anterior marginal line complete, posterior marginal line disappear before scutellum, posterior margin forward in the middle, gently backward between scutellum and posterior angle. Anterior angles acute and produced; posterior angles subrectangular. Surface densely, finely, and transversely rugo-punctate, becoming unmerged transverse punctures on posterior areas between posterior angles and scutellum, the narrow posterior margin burnished.  
Scutellum nearly triangle, broader than long, surface with dense transverse punctures, slightly sparser than those on pronotum.  
Elytra. Surface with regular striae, costal intervals lightly raised, strial punctures distinct, interval I double wider than interval II, interval II with a row of longitudinal punctures before central portion. Surface slightly corrugated, densely transverse punctate. Epipleuron slightly widened in anterior 2/5, disappearing just after middle of side.  
Propygidium. Surface of anterior half with dense transverse stripes, surface of posterior half smooth, with several long setae.  
Pygidium weakly convex in profile. Surface densely transversely striate, striae partly meshedly transversely combined together. Area before apex angle raised, apex with yellow setae.  
Abdominal ventrites. Surface with dense transverse punctures, punctures becoming denser to the sides, posterior margin smooth, each ventrite with a transverse row of long yellow setae.  
Legs. Protibia bidentate, outer margin curved, apical tooth short, slightly bend outwards, proximal tooth acute, inner spur short, positioned in opposite to proximal tooth. Mesotibia and metatibia slightly fusiform, inner surface with a row of long setae, metatibia with quite a number of deep stripes. Protarsal and mesotarsal outer claw clefted.  
Genitalia as in Figs 13–16.  
 DIFFERENTIAL DIAGNOSIS. Anomala menghaiensis sp. n. differs from most species of this genus around China and Indochina by following combination of characters: body color dark reddish-brown, with yellow spots (maybe sometimes with yellow band) slightly before the middle on each elytron, elytra glabrous and without regular striae, parameres partly membranous, membranes and osseous part wrapped into cylindrical shape generally, and left parameres have a long osseous branch. Species show common characteristics above of Anomala known were A. flavonotata Arrow, 1912; A. flavofasciata Arrow, 1912; A. projecta Lin, 2002; A. transversa Lin, 1999; and A. accincta Prokofiev, 2013. This new species can be distinguished with five similar species above by the shape of parameres (compare figs 5–6 with Lin, 1988: fig 4; Prokofiev, 2013: figs 13–14; Wang, 2022: figs 44– 47, 52–55; Zorn, 2005: figs 3–5).   
ETYMOLOGY. This species is named after its type locality Menghai county, China.  
DISTRIBUTION. Known only from its type locality in southern Yunnan province, China.
