Description. Body black, with metallic luster. Elytra with six small spots of greenish scales. Body length: 11.9–12.2 mm, largest width: 4.9– 5.4 mm.

Head almost square, parallel-sided, with large, but not extended bilobate eyes. Anterior portion of head between eyes and antennal bases with impressed longitudinal band of greenish pink scales, and thin, straight median line. Frontal part of head behind of clypeus convex, metallic glossy, with impressed longitudinal line, delicate punctation and pubescence. Frontal portion of head near clypeus with some coarse, sparse punctures. Longitudinal band of greenish scales starts from base of head, extending to anterior margin of eyes. Cheeks under eyes metallic glossy, without rudimental spots. Mandibles black, massive, very sharp. Labrum convex, metallic glossy, with distinctly concaved apical margin, with pubescence, small punctures, and covered with setae. Clypeus short, shiny, transverse, covered with setae. Surface of head with very fine punctation and fine, sparse tomentum. Basal area of antennae weakly protruding.Antennae long and slen- der; antennomeres 1 and 2 with strong metallic luster and very fine pubescence; antennomere 3 black, with short pubescence and a brush of inner preapical setae; following antennomeres with some long setae, except four apical segments; antennomeres 4 and 5 testaceous basally and darkened apically, with very fine pubescence in basal portion; remaining segments testaceous, with pubescence.

Pronotum very convex, subcylindrical, wider than long; anterior border markedly prominent, posterior border double, sinuous; pronotal disc hemispheric; metallic golden-colored, shiny, with very fine punctation, disitinctly sparser and coarser in latero-apical portions. Lateral margins of pronotum with band of greenish scales, posterior or anterior portions of pronotum without spots.

Scutellum widely rounded apically, shiny and tomentose, black. Pars stridens visible (holotype), covered with very fine transverse microsculpture.

Elytra very convex, black, with metallic luster and with six rounded, oval or triangular spots of greenish scales. First dorsal spot of each elytron located closer to base of elytra, second dorsal spot more transverse, situated closer to the first spot than to the third, and visible away from suture, but third (preapical) spot - triangular. Two lateral spots unregularly rounded. Width of elytra at shoulders: 4.9–5.4 mm. Largest width of elytra behind middle: 4.1–4.4 mm. Elytra with very fine pubescence, microsculpture and very fine, sparse punctures, sparser and coarser in anterior portion. Meso-, metaepimera and sternites spotted laterally, covered with greenish scales. Legs relatively short and robust. Femora strongly widened at apical third, shiny, with golden metallic luster, without small spot at apex, more or less pubescent. Tibia flattened at external border, with fringe of dark setae. Dorsal surface of tarsomeres covered by pale pubescence. First tarsomere with metallic luster. Apical portions of tibia and tarsi covered by row of numerous yellow setae.

Differential diagnosis. Based on the general shape of the body, the new species is similar to D. curculionoides Waterhouse, 1842 ( Fig. 6 ), but differs from this species by the following charac-

C

ters: 1) posterio-lateral portions of the dorsal disc of the pronotum without small rounded spot,

only with band of greenish scales at lateral edge,

while that in D. curculionoides with small rounded spot, and wide oval or rounded spot at lateral edge; 2) elytra more convex, each elytron with six small oval, rounded or triangular spots, while that in D. curculionoides more flattened, with seven larger, rounded or oval spots.

Etymology. Patronymic, the new species is named after well-known Russian coleopterologist Andrei

A. Legalov (Novosibirsk) in a honor of his valu-

able contributions to the study of Curculionoidea.
