- Palaearctic steppes evolved under the Cenozoic cold arid climate and megaherbivore pressure. A large portion of the biome persisted into the Holocene but has recently been subjected to human land use alternation. Pseudophilotes bavius (Lepidoptera: Lycaenidae) is a steppe specialist sporadically distributed in Eastern Europe and Pontic-Caspian region (from Transylvania to Southern Urals), the Balkans, the South-Eastern Mediterranean and Irano-Anatolian regions. We used samples covering the distribution area to assess the phylogeography and population genetics of the species based on one mitochondrial and four nuclear genes. The basal lineages are situated in the Irano-Anatolian region, forming two Evolutionary Units. The species radiated to the Balkans and Pontic-Caspian steppes probably when the climatic conditions became suitable after the mid-Pleistocene transition and formation of vast steppe biome. In these parts of the range, the species survived both glacial and interglacial periods in situ, forming a third Evolutionary Unit. In the Balkans, the individual populations are distinct and have probably been isolated for a long time, owing to the diversity of Balkan habitats. In the Pontic-Caspian region, population connectivity probably existed until recently, since the life history of the species is unlikely to include long-distance dispersal. The distribution could have become fragmented with the conversion of steppes into cropland during the past centuries. Future conservation will require proper knowledge of the distribution and habitat needs of the species. Management of inhabited sites should respect historical disturbance-succession dynamics.

- The bacterium Wolbachia infects many insect species and spreads by diverse vertical and horizontal means. As co-inherited organisms, these bacteria often cause problems in mitochondrial phylogeny inference. The phylogenetic relationships of many closely related Palaearctic blue butterflies (Lepidoptera: Lycaenidae: Polyommatinae) are ambiguous. We considered the patterns of Wolbachia infection and mitochondrial diversity in two systems: Aricia agestis/Aricia artaxerxes and the Pseudophilotes baton species complex. We sampled butterflies across their distribution ranges and sequenced one butterfly mitochondrial gene and two Wolbachia genes. Both butterfly systems had uninfected and infected populations, and harboured several Wolbachia strains. Wolbachia was highly prevalent in A. artaxerxes and the host’s mitochondrial structure was shallow, in contrast to A. agestis. Similar bacterial alleles infected both Aricia species from nearby sites, pointing to a possible horizontal transfer. Mitochondrial history of the P. baton species complex mirrored its Wolbachia infection and not the taxonomical division. Pseudophilotes baton and P. vicrama formed a hybrid zone in Europe. Wolbachia could obscure mitochondrial history, but knowledge on the infection helps us to understand the observed patterns. Testing for Wolbachia should be routine in mitochondrial DNA studies.

- This paper presents an updated checklist of the butterflies of Europe, together with their original name combinations, and their occurrence status in each European country. According to this checklist, 496 species of the superfamily Papilionoidea occur in Europe. Changes in comparison with the last version (2.6.2) of Fauna Europaea are discussed. Compared to that version, 16 species are new additions, either due to cryptic species most of which have been discovered by molecular methods (13 cases) or due to discoveries of Asian species on the eastern border of the European territory in the Ural mountains (three cases). On the other hand, nine species had to be removed from the list, because they either do not occur in Europe or lost their species status due to new evidence. In addition, three species names had to be changed and 30 species changed their combination due to new evidence on phylogenetic relationships. Furthermore, minor corrections were applied to some authors' names and years of publication. Finally, the name Polyommatusottomanus Lefèbvre, 1831, which is threatened by its senior synonym Lycaenalegeri Freyer, 1830, is declared a nomen protectum, thereby conserving its name in the current combination Lycaenaottomana.
