( Fig. 3H, N )

Labrum covered with numerous dark setae. Head black, shiny, finely punctate. Three basal segments of antennae black, with slight metallic luster and pubescence, fourth segment testaceous, with white lustrous pubescence. Remaining segments testaceous and tomentose. Pronotum convex, black and shiny. Side along the margin with broad stripe of bluish scales without additional spots in basal part and with small blue spot located centrally in the anterior pronotal margin. Scutellum black, hardly shiny, rounded and tomentose apically. Elytra short, convex, black, shiny, with blue longitudinal bands located dorsally and laterally. Dorsal and lateral bands are apically convergent. Elytra behind the shoulders on both sides with flat raised nodules. Width of elytra at the shoulders: 4.1 mm. The greatest width of elytra behind the middle: 5.0 mm. Elytra finely punctate. In basal part Elytra basally with sparse and coarse punctures and pubescence. Meso, meta-epimera and sternites with lateral spots, covered with bluish scales. Femora with small, bluish, apical spot and more or less tomentose. Surface of tarsomeres covered with grey, iridescent tomentum. Tibia and tarsi apically covered with numerous setae.

Diferential diagnosis. This new species differs from the others by the characteristic pattern of the body surface. Currently, there is no other known species in this genus with a blue longitudinal band on its dorsal surface.

Mimicry. D. vivesi sp. n. mimics the weevil Pachyrrhynchus modestior Behrens, 1887 ( Coleoptera : Curculionidae ) ( Fig. 5I, J ), with which it coexists.

Etymology. This species is named after the Spanish cerambycidologist, Eduard Vives (Terrassa, Barcelona, Spain) for his great contribution to the research of the genus Doliops Waterh.
