In the present paper, we explore the evolution of cluster structure in closely related species in the Euphydryas aurinia complex based on morphological (wing pattern, genital armatures) and molecular (cytochrome c oxidase subunit I) characters. Male genitalia differ in the length and shape of the uncus, harpe and juxta branches, by the shape of some parts of the phallus, and by the amount of spikes on the ventral section of the valva. The main trends in the vertical distribution of the E. aurinia group are dwarfism with increasing altitude, coupled with enlargement of paler and darker-coloured elements of the wing pattern, increasing the overall contrast. Unlike the Euphydryas maturna, the E. aurinia complex forms many local populations specialized under different ecological conditions, probably affected by different evolutionary scenarios. The phylogenetic analysis of the group reveals two ecologically distinct subgroups: one associated with the boreal forest-mesophyllic meadow biome and one associated with the xeromesophyllic steppe biome. Within each group, two major ecological strategies have evolved in parallel: montane and lowland. Based on the results of the analyses, we revise the nomenclature as follows: E. aurinia pyrenesdebilis (Verity, 1928), stat. rev. (= debilis Oberthür, 1909, syn.n., nomen nudum), E. aurinia bulgarica (Fruhstorfer, 1916), stat. rev., E. aurinia provincialis (Boisduval, 1828), stat. rev. and E. beckeri (Lederer, 1853), stat. rev. The following name-bearing types are designated: neotype of Papilio aurinia Rottemburg, 1775, neotype of Papilio merope de Prunner, 1798, lectotype of Melitaea beckeri Lederer, 1853, and lectotype of Melitaea aurinia banghaasi Seitz, 1908. All name-bearing types are figured. A new subspecies, Euphydryas laeta ostracon Korb, Bolshakov, Fric, ssp.n., is described (type locality by holotype data: Kazakhstan, Vostochno-Kazakhstanskaya Oblast, Shemonaikha).

A catalogue of butterflies of Russia and adjacent countries is given, with special account to the name-bearing types depository. This catalogue contains data about 86 species (3 of them are questionable) of Hesperiidae (22 genera); 47 species of Papilionidae (14 genera); 89 species of Pieridae (5 of them are questionable)  (15 genera); 1 species (1 genus) of Libytheinae(dae); 2 species of Danainae(dae) (2 genera); 160 species of Nymphalinae(dae) (1 of them is questionable) (23 genera); 259 species of Satyrinae(dae) (14 of them are questionable, mainly from genera Oeneis and Pseudochazara) (34 genera); 3 species of Riodinidae (2 genera); 318 species of Lycaenidae (11 of them are questionable, mainly from genera Neolycaena and Plebeius) (57 genera). In total: 965 species of butterflies, 174 genera, by countries: Armenia-244, Azerbaijan-225, Belarus-107, Estonia-113, Georgia-211, Kyrgyzstan-316, Kazakhstan-344, Latvia-115, Lituania-126, Moldova-87, Russia-522, Tajikistan-295, Turkmenistan-159, Ukraine-192, Uzbekistan-241. Detailed distribution and subspecific structure (if present) for every species is provided. Lectotypes of the following species-group taxa are designated: Hesperia poggei Lederer, 1858, Parnassius felderi Bremer, 1861, P. eversmanni Eversmann, 1851, P. boedromius Püngeler, 1901, Limenitis moltrechti Kardakov, 1928, L. sydyi Kindermann, 1853, L. amphyssa Ménétriès, 1859, L. doerriesi Staudinger, 1892, L. helmanni duplicata Staudinger, 1892, L. homeyeri Tancré, 1881, Argynnis penelope Staudinger, 1891, A. thore borealis Staudinger, 1861, Vanessa io geisha Stichel, [1908], Melitaea maturna staudingeri Wnukowsky, 1929 (=uralensis Staudinger, 1871), M. didymina Staudinger, 1895, Papilio fascelis Esper, 1783, Thecla quercivora Staudinger, 1887, Lycaena orion var. ornata Staudinger, 1892. The following nomenclatural acts are established: Neolycaena submontana baitenovi (Zhdanko, 2011), comb. et stat.n.

Резюме. В результате исследований в 2007-2011 годах в Республике Мордовия составлен список 157 видов чешуекрылых, из которых 150 приводятся впервые для изученной территории. 3 сложных для определения вида подтверждаются после старых указаний не лепидоптерологами. Остальные относятся к нуждающимся в дополнительном освещении.Аbstract. As a result of 2007-2011 research, a list of 157 species of Lepidoptera from the Republic of Mordovia is presented, 150 of which are new for the fauna of the Republic. Three difficult for determination species, previously known after old records by non-lepidopterists, is confirmed. Other species must be investigated additionaly.
