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

Color . Generally reddish brown, elytra lighter, rarely generally dark brown; dull, with strong greenish sheen; elytra with a yellow, narrow to broad zigzag band extending from primary costa 3 to 1, and a yellow spot on primary costa 4, rarely connected; antennae reddish 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 margins moderately convergent anteriad, anterior margin slightly convex, anterior corners obsolete and rounded; anterior margin weakly reflexed; surface with dense, large and coarse punctures. Frontoclypeal suture slightly bisinuate, distinct. Anterior third of frons and area along inner margin of eye punctate as clypeus, other portions with dense and large punctures, slightly sparser and smaller posteriad. Interocular distance/maximum head width approximately 0.65. Length of antennal club slightly longer than combined length of antennomeres 1–6. Inner margin of eye with a few moderately long setae.

Pronotum. Sides strongly convergent anteriad, lateral margin feebly incurved in anterior third or posterior third, moderately excurved at middle. Anterior angle acute and protruding, posterior angle right-angled and rounded apically. Posterior marginal line absent, other marginal lines complete. Lateral fovea indistinct. Disc with moderately dense and large punctures. Lateral margin with several long setae.

Scutellum triangular, lateral margin weakly excurved; with dense and small punctures, covered by dense and short mesonotal setae along base.

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 dense punctures, which are slightly 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 short setae from base to the level of apical protuberance, usually partly abraded.

Abdomen. Propygidium with very dense, transverse and fine striation. Pygidium with dense and transverse rugostriation, also dense on the greatest tumidity; with dense and long setae preapically, and a transverse row of long setae along posterior margin. Abdominal ventrites 1–3 strongly carinate laterally; ventrites 2–5 each with transverse and incompletely annulated punctures, short and moderately dense medially, gradually transverse and denser laterad, frequently confluent at the lateralmost area, ventrite 6 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 6.0.

Legs. Protibia bidentate, both teeth distinct and acute; apical tooth extending to anterior margin of protarsomere 2. 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 indistinct basal protuberance. 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 moderately dense and long setae, one lateral and the other submedial, also with some irregular and long setae sublaterally; 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. 19A–D.

Female. Generally dull black with strong greenish sheen, rarely elytra reddish brown around scutellum; the elytral band sometimes formed by three separate small spots. Length of antennal club approximately 0.9 times as long as combined length of antennomeres 1–6. Lateral margin of pronotum more excurved at middle, straight at anterior and posterior third; posterior angle obtuse. Lateral carina of elytra slightly wider than in male; setae along lateral margin longer. 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; inner spur inserted at mid-length of protibia; protarsomeres thinner, internomedial denticle of pro- and metatarsomere 5 acute, that of metatarsomere rather small, mesotarsomere without denticle, 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: 14.0– 14.6 mm in males and 14.0– 15.3 mm in females, greatest width: 7.7–8.1 mm in males and 7.5–8.2 mm in females.

Differential diagnosis. Anomala bomiensis sp. nov. can be distinguished from all other species of the A. flavonotata -subgroup (see discussion below) by the dull, but slightly iridescent surface of the body. The upper branch of the left paramere is horizontally protruding at middle.

Etymology. This new species is named after the type locality, Bomi County in Xizang.
