Description. Male. Body shape elongated ovoid, weakly convex.

Color . Generally dark reddish brown to black; shiny, with strong bronze or greenish luster; elytra with a yellow, narrow to broad zigzag band extending from primary costa 5 to 1; antennae reddish or yellowish brown, club darker; protibial teeth reddish brown; setae yellowish brown, robust setae reddish brown.

Head. Greatest width/length of clypeus approximately 2.3; subtrapezoidal, lateral margin straight and moderately convergent anteriad, anterior margin slightly convex, anterior corner obsolete and rounded; anterior margin weakly reflexed; surface densely and coarsely rugopunctate. Frontoclypeal suture straight, distinct. Anterior third of frons punctate as clypeus, other portions including vertex with moderately dense and large punctures, slightly sparser and smaller posteriad. Interocular distance/maximum head width approximately 0.6. Length of antennal club equally as long as combined length of antennomeres 1–6. Inner margin of eye with a few moderately long setae.

Pronotum. Sides strongly convergent anteriad, lateral margin straight in anterior third or posterior third, curved at middle. Anterior angle acute and protruding, posterior angle obtuse. Posterior marginal line broadly interrupted before scutellum, other marginal lines complete. Lateral fovea strongly impressed. Disc with moderately dense and large punctures. Lateral margin with several long setae.

Scutellum triangular, lateral margin weakly to moderately excurved; with dense and large punctures.

Elytra. Intervals slightly elevated, subsutural interstice widest; strial punctures dense and large, subsutural interstice with extensive, irregular and large punctures, interstice II with a secondary stria, all intervals with moderately dense punctures, which are slightly or distinctly smaller than strial ones. Humeral protuberance moderately prominent, apical protberance strongly prominent. Lateral carina expanded from base to apical two fifths. Epipleuron with a row of dense and moderately long setae from base to posterior margin, often partly abraded.

Abdomen. Propygidium with very dense, transverse and fine striation. Pygidium with dense and transverse striation, sparse only on the greatest tumidity; with some long setae preapically and a transverse row of long setae along posterior margin. Abdominal ventrites 1–3 strongly carinate laterally; ventrites 2–5 with transverse and incompletely annulated punctures, short and sparse medially, gradually elongated, denser laterad, frequently confluent at the lateralmost area, ventrite 6 very densely and finely rugostriolate; ventrites 2–5 each with a transverse and sparse row of long setae, dense laterally, the row of ventrite 6 present at posterior margin.

Ventral thoracic surface. Hypomeron longitudinally striolate, with moderately dense and long setae. Ventral mesothoracic surface with dense, small and confluent punctures each bearing a short seta. Ventral metathoracic surface with dense, large and annulated punctures, gradually denser and confluent laterad, with dense and rather long setae, medial area with sparse and small punctures, setae short. Metacoxa punctate as lateral metasternum but bearing sparser and shorter setae. Width of mesofemur/narrowest extremity of mesosternum approximately 6.0.

Legs. Protibia bidentate, both teeth distinct; apical tooth extending to middle of protarsomere 2, preapical tooth acute. Inner spur inserted shortly behind the level of the preapical tooth. Inner protarsal claw and outer mesotarsal claw split apically, both lower branches two times wider than their upper branches, lower branch longer in protarsal claw and equally as long as upper branch in mesotarsal claw; lower margin of lower branch of inner protarsal claw convex distally next to the internobasal notch; outer metatarsal claw slightly longer than inner one. Protarsomeres distinctly thickened, each tarsomere 5 with an acute internomedial denticle, that of protarsomere 5 largest, blunt and situated proximally, metatarsomere 5 with an additional triangular basal denticle. Ventral surface of mesofemur with a row of dense and long setae at lateral margin, a row of long and slightly robust setae submedially, additional dense and long setae between rows; ventral surface of metafemur with two rows of sparse and long setae, one lateral and the other submedial; meso- and metatibiae each bearing three transverse groups of robust setae emerging from a carina, with the basal fourth featuring some randomly arranged and shorter robust setae.

Male genitalia. See fig. 20E–H.

Female. Length of antennal club approximately 0.8 times as long as combined length of antennomeres 1–6. Lateral margin of pronotum more excurved. Lateral carina of elytra at most 1.5 times as wide as in male. Pygidium more triangular and flat preapically; ultimate abdominal ventrite 1.5 times as long as that in male medially. Apical protibial tooth spatulate, extending to anterior margin of protarsomere 2; inner spur inserted at mid-length of protibia; protarsomeres thinner, internomedial denticle of each tarsomere 5 small, that of protarsomere situated at middle and acute, basal denticle of metatarsomere 5 absent; lower branch of inner protarsal claw and outer mesotarsal claw slightly wider than upper branch, lower branch of protarsal claw as long as its upper one and the lower margin not convex.

Measurement. Body length: 13.2–14.1 mm in males and 13.2–13.9 mm in females, greatest width: 7.5–7.8 mm in males and 7.5–7.9 mm in females.

Differential diagnosis. The parameres of Anomala maedai sp. nov. are somewhat similar to those of A. luoyuensis sp. nov. But the upper branch of the left paramere is thinner. The lower branches of the parameres are broad, with only the internoapical angle protruding (the whole lower branches narrowed and rather long in A. luoyuensis sp. nov.). It is also different from other members of the A. flavonotata -subgroup by internomedial denticle of protarsomere 5, which is situated proximally in males, whereas it is situated at the middle in other species.

Etymology. This species is named after Takeshi Maeda ( Ibaraki, Japan) who collected the type series.
