Type series: Holotype: , C. VIETNAM: Quang Nam Da Nang 15-30. APR. 2009. ( NSMT) . Paratype: 1 , near Ngoe Thinh , alt. 2200 m, Kon Tum Prov., 1~ 15-IV-2010, native collector leg. ( MFPC) .

Description: Body shape elongate ovoid, strongly convex; body length: 18.0-19.0 mm, width: 9.0- 9.5 mm.

Color. Dorsal surface entirely vivid metallic green with weak iridescent shine except as follows: footstalk of antenna reddish brown, pronotum with orange band along lateral margin, pygidium with orange spot at apex, elytra with a transverse zig-zag band before the middle, consisting of three pairs of orange patches appearing on primary costae 2, 3 and 4, the latter encompassing parts of the neighboring interstices; ventral surface metallic green except as follows: sides of sternal segments orange, femora orange, abdominal ventrites reddish copper with orange lateral spots.

Head with sparse erect pale yellow setae (0.25-0.5 mm in length) along eyes; interocular distance equals 0.84 times the maximum transverse head width. Clypeus trapezoidal with rounded front angles and anterior margin; densely, somewhat rugosely punctate, punctures round (ca. 0.05 mm in diameter); anterior margin distinctly reflexed; fronto-clypeal suture weakly sinuate. Frons densely punctate, the punctures round in the middle, becoming larger anteriad, sparser posteriad. Vertex irregularly scattered with small, somewhat transverse punctures.

Pronotum 1.8 times as wide as long; sides arcuate in the middle; convergent and straight in apical 2/5, subparallel basad, widest at base; lateral marginal line almost reaching the hind angles; basal marginal line weakly indicated medially of humerus; front angles produced and acute, hind angles obtuse, rounded off; disc densely covered with transverse moderately small punctures (ca. 0.05 mm), each puncture bearing a microscopic seta; with sparse erect yellow setae (0.37-0.5 mm in length) along lateral margin.

spec. nov., holotype. 12. A. confrater spec. nov., holotype. 13. A. imperspicabilis spec. nov., holotype. Scale = 1 mm.

Scutellum 1.4 times as wide as long, apex acute; punctures equal those of pronotum.

Elytra regularly striate-sulcate; primary costae distinctly convex, interstices weakly convex; with two vague secondary costae in the subsutural interstice; striae not marked by a regular row of punctures; entire surface covered with large, very transverse, microscopic-setabearing punctures, leaving out only the ridges of primary costae and the humeral protuberance; punctures adjacent to each other, partly coalescing and forming small transverse striae; epipleura ending before the apical curvature; marginal membrane starting approximately at level of anterior third of metacoxa.

Pygidium triangular and convex, somewhat tumid; disc with reticulate striolation which is arranged concentrically around the tumidity; with sparse yellow setae (0.1-0.75 mm in length) in apical and baso-lateral portions.

Mesoventrite very narrow and somewhat concave between the approximated mesocoxae.

Metaventrite with very dense, transversely confluent punctures at the sides, sparsely punctate in the middle; with pale yellow setae (0.12-0.75 mm in length) at the sides which become sparser and shorter in the middle.

Abdominal ventrites with very transverse punctures which are separated in the middle and confluate laterally; 2nd to 4th ventrite with a transverse row of semierect brownish setae (0.2-0.63 mm in length, indistinct in the middle) and irregular short setae at the sides; sides not carinate.

Legs slender and long; protibia bidentate; terminal tooth prolonged and acute at apex in male; protarsal segment 5 thickened, ventrally with a deep concavity in the apical half; inner protarsal claw and outer mesotarsal claw apically incised; the upper branch of the inner protarsal claw small and slender, the lower branch broad, somewhat enlarged ventrally but without tooth; the upper branch of outer mesotarsal claw slightly more slender than the lower one.

Diagnosis: This species is a member of the group related to Anomala spiloptera BURMEISTER, 1855 , all of which share a distinctive structure of the aedeagus: the parameres are usually very elongate and are connected by a wide wrinkled membrane dorso-basally. The ventral plate is usually equipped with a long process resembling a narrow blade. Many species related to A. spiloptera have different color variants. Within this group, A. recordata most closely resembles Anomala iridicollis OHAUS, 1914 as well as the dark greenish forms of A. viridicostata NONFRIED, 1892 and A. spiloptera BURMEISTER, 1855 . It is, however, clearly separated from those species by the unique shape of the aedeagus (fig. 15) which is nearly symmetrical (strongly asymmetrical in A. spiloptera ), and the ventral plate has a long, strongly downwards curved process (short in A. iridicollis , nearly straight in A. viridicostata ). Moreover, males of A. viridicostata have protarsomere 5 distinctly more thickened, and in all specimens of A. iridicollis examined, the elytra were deep bluish black with orange spots, with rather weak metallic shine. Anomala recordata also has a rather broad subsutural interstice with two vague secondary costae. The subsutural interstice is distinctly narrower in A. spiloptera , while it is broad but rather flat in A. iridicollis .

Etymology: The specific epithet is formed by the Latin adjective “recordatus, -a, -um” and translates as “remembered” or “recollected”. This alludes to the number of similar species with which it might be confused.
