Description. Male. Body shape ovoid, moderately convex.

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

Head. Greatest width/length of clypeus approximately 2.2; subtrapezoidal, lateral margins 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 incurved, 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, slightly incurved in posterior third, moderately excurved at middle. Anterior angle acute and protruding, posterior angle obtuse and rounded. Posterior marginal line absent, other marginal lines complete. Lateral fovea strongly indistinct. Disc with moderately dense and large punctures. Lateral margin with several long setae.

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

Elytra. Intervals almost flat, only slightly elevated near apical protuberance, 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 and apical protuberance moderately prominent. Lateral carina expanded from base to apical two fifths. Epipleuron without obvious setae.

Abdomen. Propygidium with dense, transverse and fine striation. Pygidium with broadly rounded apex, disc with moderately dense and transverse striation, even on the greatest tumidity; with some long setae preapically and a transverse row of long setae along posterior margin. Abdominal ventrites not at all carinate laterally; ventrites 2–5 each with transverse and incompletely annulated punctures, mostely equal in width, sparse medially, gradually denser laterad, frequently confluent at the lateralmost area, ventrite 6 minutely striolate in anterior half; ventrites 2– 5 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 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 middle of protarsomere 2. Inner spur inserted shortly behind the level of the preapical tooth. Inner protarsal claw and outer mesotarsal claw split apically, lower branch of inner protarsal claw with rounded apex, longer and three times wider than its upper branch, lower branch of outer mesotarsal claw as long as and two times wider than its upper branch; lower margin of lower branch of inner protarsal claw not convex next to the internobasal notch; outer metatarsal claw slightly longer than inner one. Protarsomeres distinctly thickened, each tarsomere 5 with an internomedial denticle, that of protarsomere 5 largest, blunt and situated proximally, that of mesotarsomere 5 rather small, and that of metatarsomere 5 acute, metatarsomere 5 without 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; metafemur with two rows of moderately dense and short setae, one sublateral and the other submedial, usually abraded; 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. 16E–H.

Female. Length of antennal club approximately 0.7 times as long as combined length of antennomeres 1–6. Pronotum longer, lateral margin of pronotum more excurved at middle. Lateral carina of elytra slightly wide than 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 base 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 protarsomere 5 situated at middle, that of metatarsomere 5 largest; lower branch of inner protarsal claw and outer mesotarsal claw slightly wider than upper branch, lower branch of protarsal claw shorter than its upper one.

Measurement. Body length: 13.6 mm in males and 13.2 mm in females, greatest width: 8.1 mm in males and female.

Differential diagnosis. Anomala murzini sp. nov. is externally similar to species of the A. flavonotata -subgroup, but the lower branch of the inner protarsal claw is rounded at the apex (vs. acute in the A. flavonotata -subgroup) and the abdominal ventrites are not carinate laterally (vs. ventrites 1–3 strongly carinate). It also has a slender and trisinuate upper branch of the left paramere, which is strongly reduced in species of the A. flavonotata -subgroup. The ventral branches of the parameres are trisinuate in profile with a hook-liked apex.

Etymology. The new species is named after Sergey Murzin ( Moscow, the Russian Federation), who collected the type series.
