Description: Body shape elongate ovoid, distinctly convex; body length: 18.0- 19.5 mm, width: 9.0- 9.5 mm.

Color. Entire body deep metallic green with reddish as well as faint iridescent reflections which are stronger on elytra, pygidium and abdomen; antennae greenish black, tarsi somewhat bluish.

Head with erect yellow setae (0.38-0.5 mm in length) along eyes; interocular distance equals 0.67 times the maximum transverse head width. Clypeus broadly trapezoidal, densely punctate; the punctures round and large (ca. 0.07 mm in diameter), partly coalescent along marginal portion; anterior margin distinctly reflexed; fronto-clypeal suture weakly sinuate. Frons densely punctate, somewhat larger anteriad, sparser and smaller posteriad. Vertex with sparse, small, somewhat transverse punctures.

Pronotum 1.7 times as wide as long; sides arcuate, convergent in apical 2/5, almost straight in posterior 3/5; widest at base; anterior and lateral margin with weak marginal line; lateral marginal line extending to hind angles; posterior margin with marginal line between hind angle and scutellum; front angles produced and acute, hind angles obtuse; disc with dense small transverse punctures (ca. 0.05 mm) in the middle, punctures becoming larger laterad; with sparse erect yellow setae (ca. 0.6 mm in length) along lateral margin.

Scutellum 1.7 times as wide as long, apex broadly angulate; with sparse transverse punctures.

Elytra regularly striate-sulcate; intervals moderately convex; sutural interval elevated in the posterior 2/3 of elytra; surface covered with irregular, transverse, microscopic-seta-bearing punctures; punctures adjacent to each other, confluent towards striae, much sparser and smaller at the ridges of the intervals and the humeral protuberance; epipleura disappearing behind middle of elytron; marginal membrane starting approximately at level of anterior third of metacoxa.

Pygidium triangular, widely rounded at apex; tumid; with reticulate striolation which is arranged concentrically around the tumidity; with reddish brown setae (0.63-0.75 mm in length) at lateral and apical portion.

Mesoventrite very narrow and somewhat concave between the approximated mesocoxae.

Metaventrite reticulately rugulose, with sparse yellow setae (0.13-0.38 mm in length) in lateral portions, sparsely punctate and almost glabrous in the middle.

Abdominal ventrites transversely punctate in the middle, transversely striolate at the sides; 2nd to 4th ventrite with a transverse row of semierect brownish setae (0.08- 0.38 mm in length) in the apical half.

Legs slender and long; protibia bidentate; terminal tooth prolonged and obtuse at apex in male; protarsal segment 5 with a sharp tooth in the middle; inner protarsal claw and outer mesotarsal claw apically incised, forming two branches; the upper branch of the inner protarsal claw small and slender, the lower branch broad with a distinct tooth at its ventral margin.

Diagnosis: Anomala immeliorata is a sister species of A. confrater and can be separated from it only by the shape of the aedeagus: the hook-shaped extension of the ventral plate is more strongly curved backwards, and the parameres are nearly symmetrical, not equipped with a lateral tooth (fig. 11). Both species are similar to A. aulax and A. imperspicabilis spec. nov. but can be separated from these by the following characters: pronotum without yellowish lateral margin and without median longitudinal depression; legs green; elytra evenly striate with very convex intervals; aedeagus distinctly asymmetrical in A. immeliorata and A. confrater .

Etymology: The specific epithet is formed by the Latin adjective “immelioratus, -a, -um” and translates as “not improved”. It is an allusion to the unicolored and simple appearance of A. immeliorata compared to the similar A. aulax and A. imperspicabilis .
