Description. Body black and shiny, with slight metallic luster. Surface with spots of pale pink scales. Length: 12.0 – 14.0 mm, Width: 5.4 – 5.5 mm

Head with longitudinal band of pale pink scales between the eyes and antennal bases. Cheeks beneath eyes have small, pale, pink spots. Labrum covered with numerous setae. Head black, finely punctate, sometimes with fine microsculpture. Three basal segments of antennae black, with slight metallic luster and pubescence, fourth segment testaceous basally, with white lustrous pubescence, but remaining segments testaceous and tomentose. Pronotum convex, black, shiny, on both sides with pale, pink, lustrous spot resembling inverted umbrella, at base and/or at front with small, pale, pink spot. Scutellum rounded and tomentose apically. Elytra very convex, black, and shiny, with nine pale pink circles, five of which are dorsally and four laterally located. Apical spots confluent, but distinct. Some dorsal and/or lateral circles closer together. Second circle in dorsal row slightly transverse. Laterally, below the shoulder there is a small rudimentary spot. Width of elytra at shoulders: 3.8 - 4.6 mm. Largest width of elytra behind middle: 5.4 - 6.6 mm. Elytra finely punctate with sparse and coarse punctures and tomentose in basal part. Meso, meta-epimera and sternites with lateral spots covered with pale pink or greenish scales. Femora with small, pale, pink or greenish spot at apex and more or less tomentose. Surface of the tarsomeres covered with grey, iridescent tomentum. Tibia and tarsi apically covered with numerous setae.

Aedeagus ( Fig. 4H ).

Differential diagnosis. This new species differs from others which have a characteristically patterned body surface. The new species is somewhat similar to D. dupaxi Vives ( Figs. 3E , 4J ), however, the surface pattern and aedeagus are different.

Mimicry. D. stradinsi sp. n. mimics the weevil Pachyrrhynchus argus Pascoe, 1871 ( Coleoptera : Curculionidae ) ( Fig. 5E, F ), with which it co-exists.

Etymology. This species is named after the prominent Latvian scientist and academician, Jānis Stradiņš, in great respect, gratitude and due to his 80-year birthday.
