Taxonomic and nomenclatural notes on the Rhinusa tetra (Fabricius) species complex (Coleoptera: Curculionidae) Author Caldara, Roberto Author Casalini, Roberto Author Baviera, Cosimo text Zootaxa 2012 3329 31 40 journal article 10.5281/zenodo.281230 3aa9c3e9-4495-480b-8095-3eff3fee36a6 1175-5326 281230 Gymnetron trigonale Gyllenhal, 1838 Gymnetron trigonale was described from specimens collected at Odessa ( Ukraine ) and compared with R. antirrhini (Paykull, 1800) . Brisout de Barneville (1865) considered this taxon as a variety of R. tetra with the elytral integument broadly reddish. We examined a female syntype at NHRS labelled “ Typus / Khersonia, Lundstedt” ( lectotype here designated) and agree with Brisout de Barneville's opinion.
