Description. Body black, with strong metallic
luster. Surface of elytra with three big, greenish,
iridescent circle-shaped spots. Body length: 11.9
– 14.2 mm, largest width: 4.8 – 6.0 mm.
Head almost square, parallel-sided, with bilobate
eyes. Head between eyes and antennal bases
with longitudinal band of greenish scales and
thin, straight median line without scales.
Longitudinal band long, pointed frontally. On
front of greenish band head covered by very fine
pubescence and punctuation. Cheeks beneath
eyes with large transverse spot of greenish scales
or without it, with some punctures near eyes and
with fine transverse microsculpture. Labrum
pubescent and punctate. Head finely punctate,
glossy, with strong metallic luster; weakly convex
frontally, with very fine punctuation. First
antennomere glossy, with metallic luster, second
antennomere black and with light luster, third
antennomere dark broun basally, black and
widened apically, remaining antennomeres are
testaceous and tomentose. Pronotum convex,
shiny, with sparse coarse punctuation laterally
and with very fine microsculpture. Dorsal disc of
pronotum in middle of frontal part with short
rudimental spot of greenish scales, with large
semicircle-shaped spot of greenish scales
laterally. Disc of pronotum in centrum without
pubescence, shiny, with very fine punctuation.
Scutellum rounded apically, shiny and tomentose.
Elytra convex, shiny, with strong metallic luster
and with three circle-shaped spots of greenish
or yellow scales. Circles sometimes confluent,
with wider bands than that at D.
pachyrrhynchoides Heller, 1916. Elytra finely
punctate; on sides with lightly protrunding
shoulder bumps. Elytra behind shoulders on both
sides with wide raised nodules and impressions;
with sparse and coarse punctures and
pubescence anteriorly and laterally. Width of
elytra at shoulders: 4.5 – 5.4 mm. Largest width
of elytra behind middle: 4.8 – 6.0 mm. Meso-,
metaepimera and sternites spotted laterally,
covered with greenish scales. Femora with small
greenish or yellow spot at apex and more or less
tomentose. Dorsal surface of tarsomeres covered
by grey, tomentum. Tibia and tarsi in apical part
covered by numerous setae.

Differential diagnosis. The new species is similar
to D. pachyrrhynchoides and D. ligata
Schwarzer, 1929. All tree these species are with
tree big circle shaped spots on elytra. Shape of
these spots are specific for every species.
Different also shape of pronotum and colour of
body (Fig. 2A, B, C, D).

Mimicry. D. balalaikinsi sp. n. mimics the weevil
Pachyrrhynchus cf. reticulatus (Coleoptera:
Curculionidae) (Fig. 2E).

Etymology. This species is named after my
colleague, Latvian coleopterologist Maksims
Balalaikins (Daugavpils University, Daugavpils,
Latvia) in appreciation of cooperation.
