Description. Body black, with a strong golden, purple or greenish metallic luster. Elytra with transverse bands of greenish scales. Body length: 12.8 mm, largest width: 5.2 mm.

Head almost square, parallel-sided, with bilobate eyes. Part of head between eyes and antennal bases with impressed longitudinal band of greenish scales and thin, straight median line. Apically of greenish band some of scales white. Cheeks under eyes with spot of greenish scales and sparse puncturation. Labrum pubescent and punctate. Head metallic golden-coloured, finely punctate, with fine microsculpture, glossy, with luster; con vex fr on tally, with ver y fin e microsculpture, punctuation and tomentum. Two basal an-tenn with strong metallic luster and pubescence, third antennomere broun basally, black and widened apically, fourth antennomere testaceous basally, with very fine pubescence, remaining segments testaceous and tomentose. Pronotum very convex, metallic shiny, with microsculpture and with sparse punctuation laterally, pronotal disc with long X-shaped stripes of gr een ish scales, wh ich cir cle sh aped connected laterally. Disc of pronotum with pubescence, shiny. Scutellum rounded, shiny and tomentose. Elytra convex, shiny, with strong metallic luster and transverse stripes of greenish scales. First line to weld wide curved and go backwards on side of elytra. Next two lines transverse, almost parallel. Apical stripe triangular. Lateral side of elytra with a few protruding shoulder bumps. Elytra behind shoulders on both sides with wide raised nodules and wide impressions. Width of elytra at shoulders: 4.6 mm. Largest width of elytra behind middle: 5.2mm. Elytra with microsculpture. Anteriorly and laterally with sparse and coarse punctures and pubescence. Meso-, metaepimera and sternites spotted laterally, covered by greenish scales. Femora very shiny, with strong metallic luster and with small elongate greenish spot at apex, more or less tomentose. Dorsal surface of tarsomeres covered by grey, iridescent tomentum. Tibia and tarsi in apical part covered by numerous setae.

Differential diagnosis. The new species is similar to D. geometrica Waterhouse, 1842 by general shape of body, but differs from this species by shape of pronotum on which is long X-shaped stripes of greenish scales, which are circle shaped and connected laterally, and shape of first line of elytra, which is near suture broadly rounded and connected with second stripe, no triangular as by D. geometrica ( Fig. 1 A, B, D ). The new species is a litle similar also to D. multifasciata ( Fig. 1E ) by pattern of surface.

Mimicry. D. ageometrica sp. n. mimics the weevil Pachyrrhynchus cf. speciosus ( Curculionidae ) ( Fig. 1 E ).

Etymology. The species name ageometrica is derived from latin name “ geometrica ” and prefix “ a”, which means – “ no geometrica ”. This species name alludes to the similarity with D. geometrica .
