Taxonomic composition and zoogeographic characteristics of the flea fauna (Siphonaptera) of Russia

255 species and 59 subspecies of fleas from 55 genera of 7 families are known from Russia, which is 30% of the Palaearctic fauna. Additionally, over 187 species of 47 genera from 7 families are known from the neighboring territories of Central and Southern Europe, Transcaucasia, Kazakhstan, Middle Asia, Mongolia, Northeast China, and Japan. 13 species of 12 genera are known only from Russia. Noteworthy is the low percent of endemic species (not more than 4%) and genera (one genus) in the Russian fauna. The principal centers of taxonomic diversity in the Palaearctic, including many endemic species and genera, lie in the Eastern Asian, Central Asian, and Turano-Iranian Subregions, outside Russia and the Euro-Siberian Subregion. The bulk of the Russian fauna is formed by the species and genera of the three largest flea families: Hystrichopsyllidae, Ceratophyllidae, and Leptopsyllidae. The family Ceratophyllidae has the greatest number of genera in the Russian fauna, and Hystrichopsyllidae, the greatest number of species. Western (Western and Western-Central Palaearctic; 84 species from 41 genera of 7 families) and Eastern (Central-Eastern and Eastern Palaearctic; 78 species from 42 genera of 6 families) species are nearly equally represented in the Russian fauna.     

Zoogeographical characteristics of the Systellognatha (Plecoptera) fauna of Russia and adjacent countries

The stonefly fauna of the Systellognatha group of Russia and adjacent countries comprises 120 species belonging to 43 genera of 5 families. According to the geographical distribution, 12 groups of genera and 16 species-groups are distinguished. Most of the genera belong to the Holarctic (5), Nearctic-Eastern Palaearctic (7), Amphipacific (9), and Western Palaearctic (8) groups; among the species, the Eastern Palaearctic (29), Palaearchearctic (25), and Western Palaearctic (19) ones are prevalent. There are endemic species, especially in the Caucasus and Middle Asia.     

Mitochondrial DNA variation pattern in larches of Eastern Siberia and the Far East

Genetic variation has been studied in 32 Eastern Siberian and Far Eastern populations of Larix Mill. with the use of three mitochondrial markers based on polymerase chain reaction. Eight multilocus haplotypes with a heterogeneous spatial distribution (G _ST = 0.788, N _ST = 0.829) have been found, which indicates limited gene flows between populations. Several geographic regions with specific larch haplotype sets have been determined: (1) Japan, (2) southern Sakhalin and the Kuril Islands, (3) Primor’e and Korea, (4) Kamchatka, and (5) Eastern Siberia and the northern Far East. The haplotype fixed in the Kamchatka is absent in the Magadan oblast or Chukotka but is present in southern Primor’e and Sakhalin Island. This may be explained by either the postglacial recolonization of Kamchatka by larch that spread from Primor’e through Sakhalin and the Kuril Islands or its survival through the last glacial maximum in the Kamchatka Peninsula. The biogeography of larch and other woody plants indicate that boreal species have a common history of the colonization of Kamchatka.

Step(pe) up! Raising the profile of the Palaearctic natural grasslands

Palaearctic steppes are primary grasslands dominating the landscape of the Eurasian Grassland Belt from Central and Eastern Europe to Northern China across the temperate zone of Eurasia. We also include structurally and floristically similar habitats in North Africa, Anatolia, and Iran. The biota of the steppes are diverse, including many endemic species. As a result of the high rate of anthropogenic conversion and widespread degradation, the Palaearctic steppes have become one of the most endangered terrestrial biomes of the world. These facts underline the importance of sustaining landscape-scale biodiversity in steppes and stress the necessity of their conservation and restoration. Literature about the ecology, biodiversity, and conservation of Palaearctic steppes is not easily accessible for an international audience. Therefore, summarising the current state of knowledge as well as knowledge gaps is very timely. This Special Issue on “Palaearctic steppes: ecology, biodiversity and conservation”, comprises 17 research papers from many different regions throughout the biome, as well as a broad review synthesising current knowledge.     

Review of the ichneumon-flies of the genus <Emphasis Type="Italic">Rhorus</Emphasis> Förster, 869 (Hymenoptera,Ichneumonidae: Ctenopelmatinae): I. The species from the Far East (with description of 24 new species and with a key)

34 Palaearctic species of Rhorus are considered, 9 groups of species are distinguished, and 24 new species from the Eastern Palaearctic (mainly from the Russian Far East) and one new species reared in St. Petersburg from Phyllocolpa leucosticta are described. A key to all these species is given.     

Distribution of carpenter-moths (Lepidoptera, Cossidae) in the Palaearctic deserts

Specific features of the carpenter-moths (Cossidae) distribution in the Palaearctic deserts are considered. The Palaearctic frontier was delimited to the Arabian Peninsula (the eastern and northern parts of Arabia are attributed to the Palaearctic Region; Yemen, southwestern Saudi Arabia, and southernmost Iran belong to the Afrotropical Region). Cossidae are highly endemic to arid areas. Some Palaearctic carpenter-moth genera penetrate to Africa southward of the Sahara Desert (an important characteristic distinguishing them from most of the other Lepidoptera). The local faunas of the Palaearctic deserts are united into 4 groups: the Sahara-Arabian-Southern-Iranian, Central-Asian-Kazakhstanian, Western-Gobian, and Eastern-Gobian. In the Eastern Gobi Desert, the fauna is the most specific; it should be considered as a separate zoogeographical subregion.

Phylogeny and biogeography of Coenonympha butterflies (Nymphalidae: Satyrinae) – patterns of colonization in the Holarctic

Abstract We studied the historical biogeography of a group of butterflies in the Holarctic region belonging to the genus Coenonympha (Nymphalidae: Satyrinae: Coenonymphina), based on a phylogenetic hypothesis estimated from three genes. The genus is distributed mainly in the Palaearctic region, with two species extending into the Nearctic region. The tree is generally well supported and shows that Coenonympha is paraphyletic with respect to Lyela ( syn.n. ) and Triphysa ( syn.n. ), and we hence synonymize the latter two with Coenonympha. Within Coenonympha we identify three species groups, the tullia, glycerion and hero groups. The North American tullia exemplars are not sister to the Eurasian ones. A diva analysis indicates that the ancestor of the group was present in the Central Palaearctic or Central Palaeartic + Western Palaearctic or Central Palaearctic + Eastern Palaearctic. We conclude that the most likely origin of extant members of Coenonympha was in the Central Asian mountains. The tullia and hero groups started diverging in Europe following dispersal into the region. There have been two independent colonizations into Africa. The drying up of the Mediterranean during the Messinian period probably played an important role, allowing colonization into the Mediterranean islands and Africa.     

Petasiger oschmarini n. sp. (Digenea: Echinostomatidae) in the grebes Podiceps grisegena (Bod.) and P. auritus (L.) (Aves: Podicipedidae) from Kamchatka,Russia

A re-examination of three sets of trematodes collected in two species of grebes, Podiceps grisegena and P. auritus, from the Kamchatka region of eastern Russia, previously identified as Petasiger neocomense, revealed that they actually represent a new species, which is named Petasiger oschmarini. Characteristic morphological features of the new species include: a head collar possessing a constant number of 19 spines; a large cirrus-sac comparable in size to the ventral sucker, containing a bipartite seminal vesicle and a well-developed pars prostatica; a large bulb-like cirrus similar in size to the testes; a long forebody; a long oesophagus; testes situated obliquely or symmetrically; and lateral vitelline fields which are not confluent in the forebody. The new species is distinguished from all Palaearctic and Nearctic members of Petasiger which possess 19 collar spines. The material described by Oschmarin (1950) as P. neocomense is considered to be conspecific.     

A review of the palaearctic species of the genus <Emphasis Type="Italic">Hadrodactylus</Emphasis> Förster (Hymenoptera,Ichneumonidae, Ctenopelmatinae) with a description of five new species

30 Palaearctic species of Hadrodactylus are considered. 2 species-group with 6 subgroups are distinguished. 5 new species from the Eastern Palaearctic Region are described: Hadrodactylus arkit sp. n. (Kyrgyzstan), H. caucasicus sp. n. (Caucasus), H. nitidus sp. n., H. sibiricus sp. n., and H. taigensis sp. n. (Eastern Siberia and Far East of Russia). A new combination and a new synonymy Xenoschesis incarnator Aubert, 1985 (recte Hadrodactylus, comb. n.) = Hadrodactylus fugax almator Aubert, 1996, syn. n. are established. An annotated list of species is given with data on the distribution in Russia and adjacent territories. A key to 30 Palaearctic species is given.

Modern classification and distribution of the family Issidae Spinola (Homoptera,Auchenorrhyncha: Fulgoroidea)

The modern classification of the family Issidae s. str. is presented according to which the family consists of 3 tribes: Issini, Hemisphaeriini, and Parahiraciini and comprises a total of 994 species and subspecies in 159 genera. The largest tribe, Issini, is distributed worldwide and comprises 129 genera with 755 species and subspecies. The tribes Hemisphaeriini and Parahiraciini are much smaller and mostly distributed in the Indo-Malayan Realm with some taxa also present in the Eastern Palaearctic and the Oceania. The tribe Hemisphaeriini consists of 15 genera with 187 species and subspecies while Parahiraciini includes 14 genera with 38 species. The Palaearctic and Indo-Malayan Realms have the richest faunas of Issidae. In contrast, Equatorial Africa has a very poor fauna of the family, whereas the Australian fauna is still almost undescribed. Chimetopon camerunensis Schmidt is recorded for the first time from Central African Republic and Gabon, and Sarima erythrocyclos Fennah, from Taveuni Island (Fiji).

Zoogeographical analysis of the hoverfly fauna (Diptera, Syrphidae) of the northwestern Caucasus

The hoverfly fauna of the northwestern Caucasus comprises 257 species of 72 genera. They possess 32 types of ranges that could be united into 11 groups of ranges. Widespread species from the basis of the hoverfly fauna in the region: species with narrower ranges, those distributed in more than one zoogeographical region, and those distributed in more than one dominion, constitute 12.9%, 63.1%, and 24% of the fauna, respectively. The hoverfly fauna of the northwestern Caucasus is composed of nemoral species common for Europe and Mediterranean basin, and also by species widespread in the Palaearctic (92.9%). Autochthomous species constitute 5.5%, and species of the eastern Palaearctic origin, 1.6%. Hoverfly species with zoophagous larvae are the most widespread. The fraction of such species is low among species with narrowly local ranges (12.5%) and high among species with ranges including more than one dominion. Phytophagous species are wider represented among hoverflies with narrowly local ranges (44.7%) than among flies with interdominion ranges (8%). Ranges of dendrobiontic saprophagous species are determined by the presence of arboreal vegetation and no widespread polytopic hoverflies are found in this group. The distribution of mycetophagous species, commensals, and terrestrial saprophagous species is determined by the presence of fungi, ranges of some hymenopterans, and the presence of decaying plant remnants.
