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

Color . Generally reddish brown to black, sometimes elytra distinctly lighter; shiny, with weak greenish luster; elytra with a yellow, narrow to very broad zigzag band extending from primary costa 5 to 1, rarely from 4 to 1; antennae yellowish or reddish brown, club darker; protibial teeth reddish brown only at extremity; setae yellowish brown, robust setae reddish brown.

Head. Greatest width/length of clypeus approximately 2.4; subtrapezoidal, lateral margins straight and moderately convergent anteriad, anterior margin slightly convex, anterior corners obsolete and broadly rounded; anterior margin weakly reflexed; surface densely and coarsely rugopunctate. Frontoclypeal suture slightly bisinuate, distinct. An inverted triangular area on anterior third of frons punctate as clypeus, other portions with dense and large punctures, slightly sparser and smaller posteriad. Interocular distance/maximum head width approximately 0.6. Length of antennal club slightly shorter than 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 absent, other marginal lines complete. Lateral fovea strongly impressed. Disc with moderately dense and small punctures. Lateral margin with several long setae.

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

Elytra. Intervals slightly elevated, subsutural interstice widest; strial punctures dense and large, subsutural interstice with irregularly doubled secondary stria, interstice II with a secondary stria, all intervals with moderately dense punctures, which are 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 near apex, sometimes partly abraded.

Abdomen. Propygidium with very dense, transverse and fine striation. Pygidium with dense and transverse striation, sparse around 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, ventrite 3 slightly weaker; ventrites 2–5 with transverse and incompletely annulated punctures, short and sparse medially, gradually more transverse and denser laterad, frequently confluent at the lateralmost area, ventrite 6 moderately densely 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 5.0.

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. Each tarsomere 5 with an acute internomedial denticle, that of mesotarsomere 5 small, metatarsomere 5 with an additional triangular basal denticle. Ventral surface of mesofemur with a transverse 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 a transverse row of sparse and long setae laterally, submedial row scarcely bearing seta; 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. 21A–H.

Female. The elytral band normally narrow, usually broken up at middle or into three small spots on each elytron. Length of antennal club approximately 0.7 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 middle of protarsomere 3, preapical tooth acute; inner spur inserted at mid-length of protibia; protarsomeres thinner, internomedial denticle of each tarsomere 5 small, that of metatarsomere largest, basal denticle of metatarsomere 5 slightly weaker; 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: 12.5–14.8 mm in males and 13.5–15.1 mm in females, greatest width: 7.0– 8.8 mm in males and 7.6–9.0 mm in females.

Differential diagnosis. Anomala suavis sp. nov. is very similar to A. maedai sp. nov. However, its upper branch of the left paramere is straighter and has an acute denticle at the apex. Additionally, the ventral plate is wider between the two parameres in A. suavis sp. nov. The body of A. suavis sp. nov. is also more convex laterally.

Etymology. The Latin adjective suavis refers to the delicate sheen of the species, which gives it a soft and attractive appearance.
