A new earthworm species of the genus Drawida Michaelsen(Oligochaeta: Moniligastridae) from China

A new species of terrestrial earthworms is described as Drawida dandongensis sp. nov. from Dandong, Liaoning, China. It is distinguished from others by a pair of spermathecal pores lie in the ventral of 7/8 intersegmental furrow, and a pair of male pores lie in 10/11 intersegmental furrow, between setae b and c.     

Conservation of endemic species from the Russian Far East using seed cryopreservation

A seed response to cryopreservation has been studied in 11 endemic plant species from the Russian Far East to determine the possibility of their long-term storage. It has been shown that the cryogenic treatment does not kill seeds. The viability of 10 species did not decrease (or even increased) after their cryogenic storage. We have not revealed any deviations in the development of plants germinated from seeds stored at an extremely low temperature (−196°C). To monitor germination after long-term storage, procedures of seed germination under laboratory conditions have been developed. The results of this study contribute to the creation of low-temperature seed banks, able to conserve and restore a floral biological diversity.     

A new genus and two new species of Choniostomatidae (Copepoda) parasitic on two deep sea isopods

The systematic position of the little-deformed parasitic copepod family Nicothoidae to the much deformed family Choniostomatidae has been disputed for many years. The new genus Diexanthema gen. nov., based on Diexanthema desistoma sp. nov. and Diexanthema bathydiaita sp. nov. discovered on two deep-sea asellote isopod species, clearly links the family Nicothoidae (via male Diexanthema) to the family Choniostomatidae (via female Diexanthema). Based upon the extreme sexual dimorphism of this new genus, it is suggested that the family Nicothoidae be dissolved and its members placed within the family Choniostomatidae. It is concluded that the differences seen between these two parasitic groups is probably due more to host adaptations than reflecting any phylogenetic trend that is evolutionarily significant. It is felt that the deep-sea environment may serve as a refugium for archaic copepod forms which may possibly offer additional clues and insights into the phylogeny of the parasitic copepoda.
This investigation suggests that the life history and parasite/host relationships of Diexanthema desistoma are quite complicated and well geared to the life history of its isopod host, Chelator insignis.     

A survey of East Palaearctic Lycosidae (Araneae). 7. A new species of Acantholycosa Dahl, 1908 from the Russian Far East

Acantholycosa azarkinaesp. n. is described from the Maritime Province of Russia on the basis of both sexes. Acantholycosa norvegica (Thorell, 1872) is reported from the Maritime Province for the first time. A key and illustrations to all six species that occur in Far East Asia are provided.     

A new cave-dwelling and endemic species of the genus Pholeuonopsis (Coleoptera, Leiodidae) from Serbia

In the present study, a new species of a cavernicolous beetle is described from Serbia: Pholeuonopsis (Pholeuonopsis) zlatiborensis sp. n. (Leptodirini, Cholevinae, Leiodidae). All important taxonomic features have been thoroughly analyzed and illustrated. The new species probably belongs to an old phyletic lineage of mesogeid origin, like other known Pholeuonopsis species inhabiting cave and endogean habitats in the western part of the Balkan Peninsula. Therefore, the species is both relict and endemic inhabitant of cave habitats in Serbia.     

New species of ectoparasitic nematode of the genus Trichodorus from the coniferous forests of the Far East]

The diagnosis and figure are given of the new species of nematodes, Trichodorus yokooi sp. n., isolated from the risosphere of Abies nephrolepis and Picea ajanensis in the Maritime Territory. The new species is close to three japanese species described by Yokoo (1964, 1966) but differs from them in the spear size, the location of ventromedial papilles, excretory pore and suplementary organs, and in the structure of vagina and ovaries.     

New taxonomic data on the genus Ypsolopha Latreille (Lepidoptera,Ypsolophidae) with descriptions of two new species from the Russian Far East

Two new species of the genus Ypsolopha Latreille, 1796 are described from Far East of Russia: Ypsolopha melanofuscella sp. n. and Ypsolopha straminella sp. n. Two new synomymies are proposed: Ypsolopha ulingensis Yang, 1977, a new junior synonym of Ypsolopha costibasella (Caradja, 1939); and Cerostoma falculella Erschoff, 1877, a new junior synonym of Ypsolopha asperella Linnaeus, 1761. The species Ypsolopha costibasella Caradja, 1939, Ypsolopha nigrofasciata Yang, 1977 and Ypsolopha nigrimaculata Byun et Park, 2001 are recorded from Far East of Russia for the first time. The male genitalia of Ypsolopha nigrofasciata are described and illustrated for the first time, diagnostic genital characters are given.     

A new marine nematode species of the genus Dinetia (Nematoda: Draconematidae) from South Korea

A new draconematid nematode species of the genus Dinetia Decraemer and Gourbault, 1997 is described from the subtidal sediments and small logs from the eastern coast of South Korea. Dinetia orientalis n. sp. mainly differs from D. nycterobia Decraemer and Gourbault, 1997 by the following characters: large number of cephalic adhesion tubes (38-42 in male and 37-40 in female), number of posterior sublateral adhesion tubes (9-11 in male and 13-14 in female) and posterior subventral adhesion tubes (17-22 in male and 19-24 in female), the buccal cavity (narrow and armed with a dorsal and two weak ventrosublateral teeth), spicules (strongly arcuated and with a pair of strongly dilated gubernaculums around distal part of spicules), and higher "c" value (8.3-10.4 in male and 8.5-10.7 in female). This is the first report on free-living marine nematodes from South Korea, and the first record of the genus Dinetia in the Northwest Pacific.     

Systematics of sculpins of the genus Radulinopsis (Scorpaeniformes: Cottidae), with the description of a new species from northern Japan and the Russian Far East

The cottid genus Radulinopsis Soldatov and Lindberg is recognized as a valid taxon including two species, R. derjavini Soldatov and Lindberg and R. taranetzi sp. nov., both distributed in shallow waters around Hokkaido, Japan, and the Russian Far East. Radulinopsis taranetzi differs from R. derjavini in having an almost naked body, teeth on the prevomer, and higher meristic counts. Radulinopsis derjugini Soldatov is synonymized with R. derjavini. A key to species of Radulinopsis and related genera is given. Based on a cladistic analysis of 18 morphological characters, Radulinopsis is the sister group of the Japanese genus Astrocottus, and the monophyletic eastern North Pacific group comprising Radulinus plus Asemichthys is the sister group of the western North Pacific group of Radulinopsis plus Astrocottus. Triglops, having a wide distribution throughout the North Pacific and North Atlantic, is putatively the sister group of a monophyletic group including these four genera. Bolin's genus Radulinus (including Radulinopsis as a subgenus) and Taranetz's subfamily Radulinae (including only Radulinus and Radulinopsis) are polyphyletic and therefore invalid.

New species of pinaceous fossil wood from the Pliocene of southern Primorye (Russian Far East)

New species of the Pinaceae, Abies chavchavadzeae and Piceoxylon ussuriense, are described on the basis of fossil woods from the Pliocene of the Pavlovka lignite field (southern Primorye). For the first time, fossil wood of Abies is reported from the Russian Far East.     

A new diatom (Bacillariophyceae) genus with two new species from New Mexico,USA

A new diatom (Bacillariophyceae) genus and two new species are described from the arid region of the North American southwest. The new genus, Playaensis, and new species, P. circumfimbria and P. furtiva, are distinguished by frustule morphology and autecology. Playaensis possesses unique, narrowly lunate longitudinal ribs bordering the raphe and spathulate spines, but their evolutionary relationship to known genera is unclear. In Payton Lake, New Mexico, P. circumfimbria and P. furtiva are rare in the diatom community, and their geographic and geological extent are not known, but they may be restricted to alkaline, slightly saline lakes of the region.     

To the species composition of rhagionid flies of the group subaquilus of the genus Chrysopilus (Diptera, Rhagionidae) in the Russian Far East

A group of the species closely related to Chrysopilus subaquilus and distributed in the eastern regions of Russia is considered. Two new species are described. Ch. leleji is closely related to Ch. kurenzovi Kriv. et Sid. Its tergites II-V are blackish brown at their bases, not paler than the others; sternite VIII is broad and rectangular; tergite IX forms a distinct cone-shaped opening. Ch. paradoxus is similar to Ch. subaquilus Nag., but its clypeus is red, not brown. In addition, this species differs distinctly from all the known species of this genus in the presence of lateral tubercles on tergite IX. The main morphological characteristics of Ch. subaquilus Nag., Ch. lilianae Sob., and Ch. yezonis Nag. are analyzed.     

A new genus and two new species of aphids (Homoptera: Aphididae) from north-west India

A new aphid genus Raychaudhuriella and two new specices viz. Raychaudhuriella myzaphoides and Rhopalosiphoninus sensoriatus are described from Himachal Pradesh, north-west Himalaya. The affinity of Raychaudhuriella gen. nov. is drawn with Aspidophorodon Verma, Cavariela del Guercio, Myazphis van der Goot, Tricaudatus Narzikulov and Vesiculaphis del Guercio. Figures and biometrical data of the new species have been provided.     

A New Genus of the Family Pteromalidae (Hymenoptera,Chalcidoidea) from the Russian Far East

A new genus Tachingousagen. n. with the type species Tachingousa trjapitzinisp. n. is described from the Russian Far East. The new genus is similar to Lyubana Bou?ek, 1991, from which it may be distinguished by a large antennal clava, equal in length to the last 4 funicular segments and with a large micropilosity area, propodeum with convex nucha without distal (arcuate) costula connected with plicae.     

A new genus and two new species of Menoponidae (Insecta:Mallophaga) from New Guinea

The new genus Cavifera is described to include two species, both new– C. abdita and C. senta
The hosts for these are from New Guinea and are believed to belong to the Columbiformes. The females are characterized by having a pair of abdominal tergal sense organs of a type unknown elsewhere in the Mallophaga or possibly in the insects.     

Description of the first endemic earthworm species from Cyprus (Oligochaeta: Lumbricidae)

New earthworm samples from Cyprus are assessed and discussed. A re-evaluation of specimens previously relegated to the Southern Alpine species Perelia nematogena (Rosa, 1903), revealed two independent species: Perelia phoebea (Cognetti, 1913 Cognetti, L. (1913): Escursioni zoologiche del Dr. E. Festa nell’Isola di Rodi V. Oligocheti. Bollettino dei Musei di zoologia ed anatomia comparata della R. Università di Torino, 28, 1–6. [Google Scholar]) ,described originally from Rhodes Island, (Greece) and an undescribed species Perelia makrisi sp. n. The new species is similar also to the Levantine Pe. galileana Csuzdi &; Pavlí?ek, 2005 and corroborates the hypotheses that the autochthonous earthworm fauna of Cyprus is of Levantine origin.

Vittatidera zeaphila (Nematoda: Heteroderidae), a new genus and species of cyst nematode parasitic on corn (Zea mays)

A new genus and species of cyst nematode, Vittatidera zeaphila, is described from Tennessee. The new genus is superficially similar to Cactodera but is distinguished from other cyst-forming taxa in having a persistent lateral field in females and cysts, persistent vulval lips covering a circumfenestrate vulva, and subventral gland nuclei of the female contained in a separate small lobe. Infective juveniles (J2) are distinguished from all previously described Cactodera spp. by the short stylet in the second-stage juvenile (14-17 μm); J2 of Cactodera spp. have stylets at least 18 μm long. The new species also is unusual in that the females produce large egg masses. Known hosts are corn and goosegrass. DNA analysis suggests that Vittatidera forms a separate group apart from other cyst-forming genera within Heteroderinae.
