New data on Corixidae and Hebridae (Heteroptera) of Kazakhstan

The species Sigara (Subsigara) oxiana Jansson, 1983 (Corixidae) is recorded for the first time from Kazakhstan. New data on the distribution of two species, which are rare in Kazakhstan, Sigara (Subsigara) fossarum (Leach, 1817) and Hebrus (Hebrus) pilipes Kanyukova, 1997 (Hebridae) are also provided. Additional data on sampling localities of Callicorixa producta producta (Reuter, 1880), Corixa affinis Leach, 1817 and Corixa punctata (Illiger, 1807) in Kazakhstan are reported. Additions to the bibliography on aquatic and semiaquatic heteropterans of the Kazakh fauna are given.

Two new species of the genera Acerastes and Messatoporus (Hymenoptera: Ichneumonidae: Cryptini) from Mexico

Two species of the tribe Cryptini (Hymenoptera: Icneumonidae: Cryptinae), Acerastes nervellatus sp. nov. and Messatoporus atratus sp. nov., are described from Mexico. It is shown that Neotropical species of the genera Messatoporus Cushman, 1929 (90 species) and Polycyrtus Spinola, 1840 (155 species) in North and South Americas are mostly different, and only 2–6% of the species of these genera occur in both faunas. It suggests a high degree of isolation of these faunas from each other.

Morphology of the cephalothorax integument of Bryocamptus pygmaeus (Copepoda: Harpacticoida: Canthocamptidae), based on a new research method

The number and location of sensilla and pores of the cephalothorax integument of the species Bryocamptus pygmaeus (G.O. Sars, 1863) (Copepoda, Canthocamptidae) were studied for the first time on the material from several European regions: the southeastern part of the Bolshezemelskaya tundra (Ne­nets Autonomous District), the north of the Komi Republic, the Republic of Karelia, and the central part of European Russia (Udmurt Republic). In the samples examined, two groups of populations differing in the characters of cephalothorax integument were recognised. These differences were found to correlate with the variability of the endopod of fourth pair of female legs, which bears four setae in specimens of the eastern form, while a specimen examined from Karelia has five setae. Pore maps are composed for both groups of morphotypes. A statistical analysis was carried out based on a new technique using three-dimensional models of the cephalothorax. As a result of this analysis, a high similarity between individuals of the eastern form and differences of the latter from the Karelian specimen were revealed.

Darwin wasps of Mexico (Hymenoptera: Ichneumonidae): the subfamilies Acaenitinae, Poemeniinae and Xoridinae

Mexican species of the ichneumonid subfamilies Acaenitinae, Poemeniinae and Xoridinae are reviewed. The following genera are recorded here from Mexico: Arotes Gravenhorst, 1829 (one species) and Coleocentrus Gravenhorst, 1829 (one species) in Acaenitinae; Ganodes Townes, 1957 (one species), Podoschistus Townes, 1957 (one species), Poemenia Holmgren, 1859 (one species) and Rodrigama Gauld, 1991 (one species) in Poemeniinae; and Aplomerus Provancher, 1886 (one species), Odontocolon Cushman, 1942 (one species) and Xorides Latreille, 1809 (five species) in Xoridinae. One species, Coleocentrus clebschi Khalaim, sp. nov., is described as a new to science. The tribes Coleocentrini and Rodrigamini, the genera Coleocentrus, Podoschistus, Poemenia and Rodrigama, and the species Podoschistus vittifrons (Cresson, 1968), Rodrigama gamezi Gauld, 1991 and Aplomerus buprestivorus Rohwer, 1920 are recorded from Mexico for the first time. The taxonomic status of Ganodes mexicanus Díaz, 2008 is discussed.

A new species of the genus Holocentropus (Trichoptera: Polycentropodidae) from Rovno amber

A new caddisfly species Holocentropus tutkaktut sp. nov. (Polycentropodidae) is described from Priabonian Rovno amber (Upper Eocene, 33.9–37.8 million years old). With the new species, the family Polycentropodidae is represented in Rovno amber by 19 species, and the genus Holocentropus McLachlan, 1878, by nine species.

New data on the spider fauna of Iran (Arachnida: Araneae), part VII

New faunistic and taxonomic data are provided for 19 families of Iranian spiders. Stemonyphantes arta Esyunin et Zamani, sp. nov. (Linyphiidae) is described from a male and a female collected in the Zanjan Province. Five genera of the family Theridiidae (Pholcomma, Phoroncidia, Phycosoma, Rhomphaea and Rugathodes) and 21 species are recorded from Iran for the first time, and 119 new province records are provided for 51 species. Additionally, Megarctosa bamiana Roewer, 1960 (Lycosidae) is transferred to the genus Arctosa C.L. Koch, 1847. A mistake in the original description of Gnaphosa azerbaidzhanica Tuneva et Esyunin, 2003 (Gnaphosidae), namely a mismatch of the figures of this species with those of G. tigrina Simon, 1878, is discussed and corrected here. Considering the results presented in this paper, the total number of spiders recorded from Iran is raised to 888 species in 321 genera.

A new species of Microcosmus (Tunicata: Ascidiacea: Bolteniidae) from the Sea of Okhotsk

A large solitary ascidian Microcosmus armatus sp. nov., described from the Sea of Okhotsk, represents the first record of the genus Microcosmus Heller, 1877 in the cold waters of the Northwestern Pacific. The genus belongs to the family Bolteniidae formerly known as Pyuridae.

Review of the genus Bugacia (Hymenoptera: Chalcidoidea: Pteromalidae) from Japan, with the description of a new species

A short review of the genus Bugacia Erdös, 1946 from Japan is given. From this country, a new species Bugacia akutagawai sp. nov. is described and illustrated, and B. arenaria Erdös, 1946 is recorded for the first time. A key for the identification of the two species known from Japan is given.

Zunielmis pax, a new genus and species of riffle beetles (Coleoptera: ­Elmidae) from Colombia

A new riffle beetle, Zunielmis pax gen. et sp. nov., is described from Colombia (Vichada, Puerto Carreño, Bita River basin). It can be distinguished from all the other elmids by having large areas of a microgranular mesh (plastron) on the pronotum and elytra, crenulate lateral margin of the latter two, the shorter interocular distance than diameter of each eye, as well as by the characters of the structure of mandibles, the shape and sculpture of pronotum, and the structure of mesosternum, mesotibiae and elytra. The imagoes were collected on freshwater sponges. The habitat, where the new species was found, is described, and the adaptive meaning of the characteristics of plastron are discussed. Drawings and photographs of the adult habitus, distinctive morphological characters, and male and female genitalia are provided.

Gorgonactis marisalbi, a new genus and species of burrowing sea anemones (Anthozoa: Actiniaria: Halcampidae) from the White Sea

New genus and species of burrowing sea anemones of the family Halcampidae, Gorgonactis marisalbi gen. et sp. nov., are described from the White Sea (Chupa Bay). The new taxa are characterised by unique characters not found in other members of this family: a simple, strong marginal sphincter, very long tentacles and their large spirocysts.
