Abstract: Two new species of Bryocamptus Chappuis, 1929 from the Russian Arctic from the Bryocamptus minutus species group are described: Bryocamptus putoranus sp. nov. and Bryocamptus abramovae sp. nov. A complete morphological comparison of the new species with the type species Bryocamptus minutus (Claus, 1863) was carried out. Significant interspecific differences were shown at the level of microcharacters, such as integumental sensillae and pores, ornamentation of segments of mouthparts and swimming legs, and pores on swimming legs. A significant correlation has also been shown in the shape of the caudal rami of the females and the antennules of the males, which is likely caused by an evolutionary sexual arms race. Bryocamptus putoranus sp. nov. and B. minutus have a similar structure of caudal rami, but completely different male antennules, which may indicate a convergent origin of modifications and highlights the importance of depicting male antennules in the species descriptions.

First data on the Hirudinea fauna of lotic ecosystems of the Khanty-Mansi Autonomous Area (Russia) https://zookeys.pensoft.net/article/71859/ ZooKeys 1082: 73-85

DOI: 10.3897/zookeys.1082.71859

Authors: Lyudmila I. Fedorova, Irina A. Kaygorodova

Abstract: Hirudinea, a small and ecologically important group of aquatic organisms, is poorly studied in northern Eurasia. In this study, we demyth the idea of the faunistic poverty of this region and present the first findings of rheophilic leeches from the Khanty-Mansi Autonomous Area, Russia. Investigation of 25 rivers (Severnaya Sosva, Ob, Konda-Irtysh, and Bolshoi Yugan river basins) resulted in finding 10 leech species with parasitic and non-parasitic life strategies. These species belong to two orders (Rhynchobdellida and Arhynchobdellida), three families (Glossiphoniidae, Piscicolidae, and Erpobdellidae) and six genera (Alboglossiphonia, Glossiphonia, Helobdella, Hemiclepsis, Piscicola, and Erpobdella). Five species, A. hyalina, G. verrucata, E. monostriata, E. vilnensis, and potentially new morphological species of piscine leeches Piscicola sp., have been discovered for the first time in Western Siberia. Data on species diversity of rheophilic leeches include the exact systematic position for all leech taxa. Each species from the list is supplemented with information about its geographical distribution.

An example of a possible leech-bryozoan association in freshwater https://zookeys.pensoft.net/article/28088/ ZooKeys 794: 23-30

DOI: 10.3897/zookeys.794.28088

Authors: Anna L. Klass, Svetlana E. Sokolova, Alexander V. Kondakov, Yuliya V. Bespalaya, Mikhail Yu. Gofarov, Alena A. Tomilova, Ilya V. Vikhrev, Ivan N. Bolotov

Abstract: Associations of various invertebrate species with bryozoans and sponges are a well-known marine phenomenon but such epizooic communities are far less diverse in freshwater environments. Here an occurrence of numerous leeches Alboglossiphonia cf. papillosa (Braun, 1805), in interstitial spaces between zooids of a colony of the freshwater bryozoan species Plumatella aff. fungosa (Pallas, 1768) in Eastern Siberia is described. To the best of our knowledge, this record appears to be the first known example of a leech-bryozoan association, although such relationships deserve further research.

Millipede and centipede assemblages on the northern and southern slopes of the lowland Altais, southwestern Siberia, Russia (Diplopoda, Chilopoda) https://zookeys.pensoft.net/article/21936/ ZooKeys 741: 219-254

DOI: 10.3897/zookeys.741.21936

Authors: Pavel S. Nefediev, Gyulli Sh. Farzalieva, Ivan H. Tuf, Khozhiakbar Kh. Nedoev, Saparmurad T. Niyazov

Abstract: The total species richness in the myriapod assemblages of the lowland Altais near Charyshskoe Village, Altai Province, southwestern Siberia, Russia is estimated to be at least 19 species from ten genera, eight families, five orders, and two classes. The following species are new to SW Siberia: Lithobius (Ezembius) ostiacorum Stuxberg, 1876, L. vagabundus Stuxberg, 1876, and L. (Monotarsobius) nordenskioeldii Stuxberg, 1876, while L. (E.) proximus Sseliwanoff, 1880 and L. (M.) insolens Dányi & Tuf, 2012 are recorded for the first time from the Altai Province of Russia. A species of Strigamia which is morphologically similar to Strigamia cf. transsilvanica (Verhoeff, 1928) has been found in the study area but its true specific identity is yet to be determined. The seasonal dynamics of myriapod assemblages in terms of the species diversity, density, sex-age structure, and vertical distribution along the soil profile have been studied with regard to the different slope exposures.

Systematics and biology of some species of Micrurapteryx Spuler (Lepidoptera, Gracillariidae) from the Holarctic Region, with re-description of M. caraganella (Hering) from Siberia https://zookeys.pensoft.net/article/7166/ ZooKeys 579: 99-156

DOI: 10.3897/zookeys.579.7166

Authors: Natalia Kirichenko, Paolo Triberti, Marko Mutanen, Emmanuelle Magnoux, Jean-François Landry, Carlos Lopez-Vaamonde

Abstract: During a DNA barcoding campaign of leaf-mining insects from Siberia, a genetically divergent lineage of a gracillariid belonging to the genus Micrurapteryx was discovered, whose larvae developed on Caragana Fabr. and Medicago L. (Fabaceae). Specimens from Siberia showed similar external morphology to the Palearctic Micrurapteryx gradatella and the Nearctic Parectopa occulta but differed in male genitalia, DNA barcodes, and nuclear genes histone H3 and 28S. Members of this lineage are re-described here as Micrurapteryx caraganella (Hering, 1957), comb. n., an available name published with only a brief description of its larva and leaf mine. Micrurapteryx caraganella is widely distributed throughout Siberia, from Tyumen oblast in the West to Transbaikalia in the East. Occasionally it may severely affect its main host, Caragana arborescens Lam. This species has been confused in the past with Micrurapteryx gradatella in Siberia, but field observations confirm that M. gradatella exists in Siberia and is sympatric with M. caraganella, at least in the Krasnoyarsk region, where it feeds on different host plants (Vicia amoena Fisch. and Vicia sp.). In addition, based on both morphological and molecular evidence as well as examination of type specimens, the North American Parectopa occulta Braun, 1922 and Parectopa albicostella Braun, 1925 are transferred to Micrurapteryx as M. occulta (Braun, 1922), comb. n. with albicostella as its junior synonym (syn. n.). Characters used to distinguish Micrurapteryx from Parectopa are presented and illustrated. These findings provide another example of the potential of DNA barcoding to reveal overlooked species and illuminate nomenclatural problems.

A long-living species of the hydrophiloid beetles: Helophorus sibiricus from the early Miocene deposits of Kartashevo (Siberia, Russia) https://zookeys.pensoft.net/article/2748/ ZooKeys 130: 239-254

DOI: 10.3897/zookeys.130.1378

Authors: Martin Fikácek, Alexander Prokin, Robert Angus

Abstract: The recent hydrophiloid species Helophorus (Gephelophorus) sibiricus (Motschulsky, 1860) is recorded from the early Miocene deposits of Kartashevo assigned to the Ombinsk Formation. A detailed comparison with recent specimens allowed a confident identification of the fossil specimen, which is therefore the oldest record of a recent species for the Hydrophiloidea. The paleodistribution as well as recent distribution of the species is summarized, and the relevance of the fossil is discussed. In addition, the complex geological settings of the Kartashevo area are briefly summarized.

New Palaearctic species of the tribe Thalassaphorurini Pomorski, 1998 (Collembola, Onychiuridae) https://zookeys.pensoft.net/article/2709/ ZooKeys 126: 1-38

DOI: 10.3897/zookeys.126.1229

Authors: Anatoly Babenko, Ayuna Chimitova, Sophya Stebaeva

Abstract: The paper is devoted to a taxonomic revision of the genus Sensillonychiurus Pomorski et Sveenkova, 2006. Five new species of this genus, i.e. S. mirus sp. n., S. taimyrensis sp. n., S. vegae sp. n., S. vitimicus sp. n., and S. amuricus sp. n., as well as three new species of the related genus Allonychiurus Yoshii, 1995, i.e. A. subvolinensis sp. n., A. elikonius sp. n., and A. unisetosus sp. n. are being described from various regions of Eurasia. The diagnoses of both genera are amended to include described species. Two genera, Tantulonychiurus Pomorski, 1996 and Thibaudichiurus Weiner, 1996, are treated as junior synonyms of the genus Allonychiurus. Agraphorura eisi (Rusek, 1976) is transferred to Sensillonychiurus; Tantulonychiurus volinensis (Szeptycki, 1964) and T. asiaticus Babenko, 2007 to Allonychiurus. A review of morphological peculiarities of Sensillonychiurus is performed, comparisons with the other genera of Thalassaphorurini given, and a key to the known species provided.

Sub-fossil beetle assemblages associated with the “mammoth fauna” in the Late Pleistocene localities of the Ural Mountains and West Siberia https://zookeys.pensoft.net/article/2417/ ZooKeys 100: 149-169

DOI: 10.3897/zookeys.100.1524

Authors: Evgeniy Zinovyev

Abstract: The distribution of beetles at the end of the Middle Pleninglacial (=terminal Quaternary) was examined based on sub-fossil material from the Ural Mountains and Western Siberia, Russia. All relevant localities of fossil insects have similar radiocarbon dates, ranging between 33,000 and 22,000 C14 years ago. Being situated across the vast territory from the southern Ural Mountains in the South to the middle Yamal Peninsula in the North, they allow latitudinal changes in beetle assemblages of that time to be traced. These beetles lived simultaneously with mammals of the so-called “mammoth fauna” with mammoth, bison, and wooly rhinoceros, the often co-occurring mega-mammalian bones at some of the sites being evidence of this. The beetle assemblages found between 59° and 57°N appear to be the most interesting. Their bulk is referred to as a “mixed” type, one which includes a characteristic combination of arcto-boreal, boreal, steppe and polyzonal species showing no analogues among recent insect complexes. These peculiar faunas seem to have represented a particular zonal type, which disappeared since the end of the Last Glaciation to arrive here with the extinction of the mammoth biota. In contrast, on the sites lying north of 60°N, the beetle communities were similar to modern sub-arctic and arctic faunas, yet with the participation of some sub-boreal steppe components, such as Poecilus ravus Lutshnik and Carabus sibiricus Fischer-Waldheim. This information, when compared with our knowledge of synchronous insect faunas from other regions of northern Eurasia, suggests that the former distribution of beetles in this region could be accounted for both by palaeo-environmental conditions and the impact of grazing by large ruminant mammals across the so-called “mammoth savannas”.

Review of tapeworms of rodents in the Republic of Buryatia, with emphasis on anoplocephalid cestodes https://zookeys.pensoft.net/article/1974/ ZooKeys 8: 1-18

DOI: 10.3897/zookeys.8.58

Authors: Voitto Haukisalmi, Heikki Henttonen, Lotta Hardman, Michael Hardman, Juha Laakkonen, Galina Murueva, Jukka Niemimaa, Stanislav Shulunov, Olli Vapalahti

Abstract: Examination of ca. 500 rodents [Microtus spp., Myodes spp., Cricetulus barabensis (Pallas), Apodemus peninsulae Thomas] from 14 localities in the Republic of Buryatia (Russian Federation) revealed a minimum of 11 cestode species representing Anoplocephaloides Baer, 1923 s. str. (1 species), Paranoplocephala Lühe, 1910 s. l. (5 species), Catenotaenia Janicki, 1904 (2 species), Arostrilepis Mas-Coma & Tenora, 1997 (at least 2 species) and Rodentolepis Spasskii, 1954 (1 species). At least 5 of these species are previously unknown. The taxonomic and phylogenetic position of Buryatian Paranoplocephala-species was defined by cytochrome oxidase I (COI) sequences (mtDNA). The phylogenetic analysis also confirmed the status of Parandrya Gulyaev & Chechulin, 1996 as a junior synonym of Paranoplocephala s. l.. The species diversity of anoplocephalid cestodes was significantly lower in Buryatia and North-East Siberia (6-7 species) than in Europe (17 species). The connections of the anoplocephalid fauna of Buryatia seem to be closer with Beringia (North-East Siberia and Alaska) than with Europe. The present study demonstrated high spatial variation (patchiness) among study sites in cestodes of Buryatian rodents, with the exception of the ubiquitous Arostrilepis horrida (von Linstow, 1901)-complex.
