Polydrusus cervinus (LINNAEUS, 1758)

Taxonomic notes:

Polydrusus cervinus is a highly variable species with a huge distribution range over the whole of Europe. Members of this species were described for many times. Here the type series of P. iris, already proposed to be a synonym of P. cervinus (Dalla Torre et al., 1936), is critically examined. It consists of three syntypes obviously belonging to two different species, Polydrusus cervinus and Pachyrhinus mustela (Herbst, 1797) . This situation requires a lectotype designation of Curculio iris for the sake of stability of nomenclature.

Type material:

Lectotype, male, here designated (ZMUC): ‘iris’, ‘Lectotypus Curculio iris Fabricius Yunakov des. 2010’, ‘ Polydrusus cervinus (L.) Yunakov det.’ . Paralectotypes: 1 ♀ (ZMUC), ‘iris’, ‘Paralectotypes Curculio iris Fabricius Yunakov des. 2010’, ‘ Polydrusus cervinus (L.) Yunakov det.’; 1 ♀ (ZMUC), ‘iris’, ‘Paralectotypes Curculio iris Fabricius Yunakov des. 2010’, ‘ Pachyrhinus mustela (Hbst.) Yunakov det.’.
