Abstract: Five species of the Oulema melanopus group are recognized in the western
Palaearctic Region: O. melanopus (Linnaeus, 1758), O. rufocyanea (Suffrian,
1847), O. duftschmidi (Redtenbacher, 1874), O. mauroi sp. nov. (northern Italy),
and O. verae sp. nov. (Spain and Portugal). The two new species are described
and illustrated. The nomenclature of the group is discussed in detail. Oulema
rufocyanea is proved to be a validly described species different to O.
duftschmidi. To fix the nomenclatural stability of the whole group and avoid
subsequent misintepretations, neotypes are designated for Crioceris melanopoda
O. F. Müller, 1776; Crioceris hordei Geoffroy, 1785; and Lema cyanella var.
atrata Waltl, 1835 (all conspecific with O. melanopus). The primary type
specimens or their photographs were examined if they exist. The spelling Oulema
melanopus is fixed as correct and explained. Variation in the cytochrome c
oxidase (cox1) gene across specimens of all the species has been analysed. All
species in the group had extremely similar haplotypes, with interspecific
sequence similarities between 90.5?99.5 %, compared to intraspecific sequence
similarities between 91.6?100 %. As a result, the phylogenetic relationships
among species in the group were not well resolved based on cox1 sequences.
