Lagriadoliops gen. nov.

Type species: Lagriadoliops anichtchenkoi sp. n.

Description. Head relatively small, slightly indrawn into pronotum. Eyes medium-large, double-lobed and they surround antennal bases. Forehead slightly trapezium-shaped and deeply sunken between strongly raised antennal bases. Head covered with silvery tomentum. Antennae relatively short, do not reach elytral apex, black, antennomere I russet at basis. Antennomere III widened at apex, but not dentiform. Antennae fully or partly covered with silvery tomentum: antennomeres I-II fully covered, almost all antennomere III covered, with exception of widest part, antennomeres IV-VII silvery at basis and/or at lower side. Residual antennomeres and separate parts in previously mentioned antennomeres covered with dark tomentum.

Pronotum longer than wide, with almost parallel sides. In direction from sides to basis, pronotum slightly compressed, therefore, not fully cylindrical. Dorsal surface black, slightly matte, with moderate metallic coppery gloss that results by strong microsculpture. Pronotum disc roughly and intensively dotted. In lateral direction, dots less rough and more diffuse. Pronotum disc russet at both sides and at base. Pronotum covered with silvery tomentum.

Coxae and femora russet. Femora slightly darker at apical parts. Tibiae mostly dark, but russet colour also visible. Darker places with metallic coppery gloss. Legs covered with intense, silvery pubescence, with black setae in both sides and at apex. Protibiae almost cylindrical, not strongly widened as inrelated genus Lamprobityle Heller. Scutellum relatively small, triangularly narrowed and broadly rounded at end, covered with silvery tomentum.

Elytra elongated, not parallel sided, slightly narrowed behind humeri, widened before apex. Elytral discs behind humeri fully smooth, without strongly raised convex humps at basal third and without wide, transversal dent. Elytral surface intensively and evenly dotted, covered with reticulate microsculpture, with matte metallic gloss and intense, silvery tomentum.

Ventral side of body russet, dotted in many places and covered with silvery tomentum.

Comparative notes. A new genus is morphologically similar to the genus Lamprobityle Heller , but differ from it by some morphological characters: 1) protibiae are almost cylindrical and not widened at apex, 2) elytra are without strongly raised convex humps and transversal impression, fully smooth in the first third behind humeri, 3) elytra are covered with intense, even and silvery tomentum. The new genus has also different shape of antennomere III: it is widened, but not typically dentiform as in the Lamprobityle . The new genus characterized by the relatively smaller eyes, different dot patterns and by the coloration of certain parts of the body.

Etymology. The name of the new genus Lagriadoliops gen. nov. is derived from genus Lagria Fabricius, 1775 ( Coleoptera : Tenebrionidae ) and Doliops Waterhause ( Coleoptera : Cerambycidae ), highlighting its similarity to these genera, especially with the genus Stenodoliops Vives that is now the synonym of the genus Lamprobityle Heller (Barševskis & Jaeger 2014) . Possibly that Lagriadoliops gen. nov. mimics some of the Lagriinae representatives due to their similarity.
