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; convex frontally, with very fine 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 greenish scales, which circle shaped
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.
