Polydrusus impar GOZIS, 1882

vranicensis Reitter, 1905: 247, syn. n.

Taxonomic notes:

According to ICZN (article 45.6.4), Polydrusus impar var. vranicensis has to be treated as subspecies. The type locality is in Bosnian highlands, where this form occurs in the subalpine zone. The specimens differ from the common appearance of P. impar only in the absence of scales with metallic shine in the body vestiture, as also mentioned by E. Reitter in the original descrip-description. A reduction of scales with metallic shine in the vestiture is very common among Entiminae groups in which the vestiture usually contains such scales. For example, complete reduction of such scales can be observed in some specimens of Polydrusus amoenus Germar, 1824 , Phyllobius pomaceu s Gyllenhal, 1834, and Ph. glaucus (Scopoli, 1763) . There are no other morphological reasons to discriminate P. impar vranicensis from typical specimens of P. impar , which occur in Vranice Planina, too.
