Description. Body black, very shiny, with a strong, coppery luster. Surface with spots of pale pink or greenish scales. Length: 13.0 mm, Width: 5.7 - 5.8 mm.
Part of head between eyes and antennal bases with longitudinal band of pale pink or greenish scales and thin, straight median line without scales. Cheeks beneath the eyes with very small, pale pink spots consisting of a few scales. Labrum pubescent. Head black, finely punctate, glossy, with metallic luster. Three basal segments of antennae black with metallic luster and pubescence, fourth segment basally testaceous, with very fine white pubescence, and the remaining segments are testaceous and tomentose.Pronotum convex, black, shiny, with expressed copper luster. Lateral margin with stripe of pink or greenish scales. Base of pronotum with small, pale pink spot on disk. Scutellum shiny, with metallic luster; apically - rounded and tomentose. Elytra convex, black, shiny, with distinct copper luster, each elytron with seven spots of pale pink or greenish scales, of which four of the spots are located dorsally and three laterally. The apical spot is larger than the pre-apical one, inclined to side. Basal elongated spot close to basal margin of elytra. Second dorsal spot transverse. Shoulders of elytra protruding, shiny. Elytra behind shoulders on both sides with raised nodules. Width of elytra at shoulders: 4.7 - 5.2 mm. The largest width of the elytron is behind the middle: 5.7 - 5.8 mm. Elytra finely punctate. Anteriorly and laterally with sparse and coarse punctures and pubescence. Meso-, metaepimera and sternites spotted laterally, covered with pale pink or greenish scales. Femora with small pale pink or greenish spot at apex and more or less tomentose. Dorsal surface of tarsomeres covered by grey, iridescent tomentum. Tibia and tarsi in apical part covered by numerous setae.
Aedeagus (Fig. 4A).
Differential diagnosis. The new species is similar to D. curculionoides Waterhouse, 1841 (2D, K) in shape and body size, by the number (both species with seven spots on each elytron) and shape of elytral markings, however, the surface pattern is slightly different. The elytra of D. curculionoides Waterh. behind the shoulders, without projection raised nodules, the shape of spots is different. In both species, the aedeagi are different (Fig. 4A, C). The pronotum of the new species has a stripe of pink or greenish scales along the lateral margin, but in D. curculionoides Waterh. there is a stripe of pink or greenish scales along the lateral margin and in the anterior part it has a second small, round spot, covered with pink or greenish scales. The third antennomere is black, but in D. curculionoides Waterh. it is testaceous basally.
D. anichtchenkoi sp. n. is similar also to D. animula Kriesche (Fig. 2A, B, I), D. duodecimpunctata Heller (Fig. 2F, M), D. shavrini sp. n. (Fig. 2G, N) and D. gutowskii sp. n. (Fig. 2E, L), but differs from them by the number, size and shape of elytral spots, the colour of the elytra and the shape of the male genitalia (Fig. 4A, E, G).
Mimicry. D. anichtchenkoi sp. n. mimics the weevil Pachyrrhynchus erichsoni Waterhouse, 1841 (Coleoptera: Curculionidae) (Fig. 5G, H).
Etymology. This species is named after my colleague and friend, the Russian carabidologist AlexanderAnichtchenko (Daugavpils University, Institute of Systematic Biology, Coleopterological Research Center, Ilgas, Latvia), in appreciation of cooperation.
