A new weevil of the subgenus Otismotilus Reitter, 1912, genus Otiorhynchus Germar, 1824 (Coleoptera: Curculionidae: Entiminae) from the Caucasus

A brief morphological characteristic of the subgenus Otismotilus Reitter, 1912 is given. Otiorhynchus paradigitalis sp. n. is described from Zekari Pass in Georgia. Diagnosis of a new species: the species belongs to the species-subgroup with thickened antennae (O. digitalis, O. depressus, O. oez...

Otiorhynchus paradigitalis sp. n. is described from Zekari Pass in Georgia. Diagnosis of a new species: the species belongs to the species-subgroup with thickened antennae (O. digitalis, O. depressus, O. oezbeki and O. kataevi) in the species-group granulatopunctatus. Otiorhynchus paradigitalis sp. n. is most similar to O. digitalis, from which it differs by the slightly shorter epistomal angles of females, weakly transverse 3rd funicular segment, oval-shaped elytra widely rounded apically, shorter setae on elytral intervals, shorter manubrium of spiculum ventrale, closely located (almost touching each other) ramus and collum of the spermatheca and slightly smaller stylus on coxites. The new species is also similar to O. oezbeki by the horn-like elongate male epistomal angles, almost reaching the mandibular apex and also by the form of elytra with straight or slightly concave sides before the base; O. paradigitalis sp. n. differs from the mentioned species by the weakly convex disc of pronotum, more elongate 2nd funicular segment, right outer apical angle of the fore tibia and distinctly widened from the outside corbel of the hind tibia.
