Abstract
Results of the investigation of the subgenus Nubidanus Rtt. (sensu Reitter) of the genus Otiorhynchus are reported. The impexus species-group of the subgenus Nubidanus comprises 5 species from the Caucasus: O. impexus, O. juvenilis, O. poricollis, O. jarpachlinus, and O. hajastani. Morphological diagnoses and detailed distribution patterns of the species are given. Lectotypes of O. poricollis and O. jarpachlinus are designated. A new synonymy is established: O. poricollis Schoenherr, 1832 = O. breviusculus Stierlin, 1875, syn. n. Variants of the genesis scenario of the impexus species-group in the eastern part of the Caucasus are discussed.
