New deep-sea species of (Nematoda, Leptosomatidae) from the North-Western Pacific: an integrative taxonomy and phylogeny.

Marimermithid nematodes parasitising invertebrates are mainly found in the deep-sea environments. Several adult and juvenile specimens marimermithids of the genus have been found in bottom sediments and inside Polychaeta during recent cruises to the Kuril-Kamchatka trench and the Kuril Basin (the Sea of Okhotsk). New species are described based on integrative study.

The first record of Gnathostenetroididea Kussakin, 1967 from Australian waters with description of four new species of Gnathostenetroides Amar, 1957 (Crustacea: Isopoda: Asellota) from the Great Barrier Reef.

The asellote family Gnathostenetroididae Kussakin, 1967 is reported for the first time from Australian waters. Four new species of Gnathostenetroides Amar, 1957 from the Great Barrier Reef are described. The genus Maresiella Fresi and Scipione, 1980 is here placed into synonymy with Gnathostenetroides and a new diagnosis is given for Gnathostenetroides together with a key to the 12 species and a map of the distribution of the genus.

A survey of the Lohmander, 1944 from Central Asia (Araneae, Clubiondae).

Latreille, 1804, with more than 500 named species, is one of the largest genera of Araneae. The genus has 15 synonyms, most of which are not listed in the World Spider Catalog (2018) and unknown to many arachnologists. The most comprehensive survey of sensu lato by Wunderlich (2011) also lacked a few synonyms.

Revision of the genus (Nematoda: Sphaerolaimidae) with description of new species.

The family Sphaerolaimidae Filipjev, 1918 includes nematodes that are characterized by the finely striated cuticle, round amphids, broad buccal cavity with longitudinal ribs, and single anterior ovary in females. Parasphaerolaimus species from this family are found in intertidal and subtidal sediments and have also been reported from mangroves and estuaries. Parasphaerolaimus pilosus sp.

Redescription of two Ctenidae (Araneae) from Taiwan.

Two ctenid species, Anahita maolan Zhu, Chen & Song, 1999 and Ctenus yaeyamensis Yoshida, 1998 from Taiwan are redescribed in detail based on both sexes. Anahita maolan is reported from Taiwan for the first time. For both species, Kenting National Park (southernmost Taiwan) is the southernmost known locality.

Redescription of Draposa subhadrae (Patel & Reddy, 1993) (Araneae: Lycosidae, Pardosinae).

Draposa Kronestedt, 2010 is a small genus of Pardosinae spiders. Currently it encompasses 10 species (World Spider Catalog 2016) distributed from Pakistan to Southeast China. Most species of the genus, except for D.

Molecular analysis of the Pygospio elegans group of species (Annelida: Spionidae).

Pygospio elegans Claparède, 1863, the type species of the genus Pygospio, was originally described from Normandy, France, and later widely reported from boreal waters in the northern hemisphere. Sequence data of four gene fragments (2576 bp in total) of the mitochondrial 16S rDNA, nuclear 18S and 28S rDNA, and Histone 3 have shown that individuals from California and Oregon, USA, Scotland and the White Sea, Russia were genetically similar (the average p-distances for the combined data between the four groups ranged from 0.04 to 0.

A new species of Anthonympha Moriuti (Lepidoptera: Plutellidae) from Russian Far East, with annotated check list of the genus.

Anthonympha rossica sp. nov., is described and illustrated.

Description of new species of Phanodermopsis (Enoplida, Phanodermatidae) with key to genera of family Phanodermatidae and pictorial key to Phanodermopsis species.

A new representative of the family Phanodermatidae, Phanodermopsis nana sp. n., is described.

A redescription of the ant mimicking spider Myrmecium gounellei (Araneae: Corinnidae, Castianeirinae), with notes on the genus.

Myrmecium Latreille, 1824 is a relatively large genus of Castianeirinae with 16 species, distributed exclusively in the Neotropics (WSC 2015). Although this genus is rather well known as a good example of ant mimicking spiders, its taxonomy is very poorly studied. Two of its species are described based on unknown sex; one species is described based on a juvenile; eight species are known based on a single sex: for seven, only females are known, and for one, only a male is known (Platnick 2014).

Anomalous sea surface structures as an object of statistical topography.

By exploiting ideas of statistical topography, we analyze the stochastic boundary problem of emergence of anomalous high structures on the sea surface. The kinematic boundary condition on the sea surface is assumed to be a closed stochastic quasilinear equation. Applying the stochastic Liouville equation, and presuming the stochastic nature of a given hydrodynamic velocity field within the diffusion approximation, we derive an equation for a spatially single-point, simultaneous joint probability density of the surface elevation field and its gradient.
