Benthic habitats in the Tikhaya Bight (the Hooker Island, Franz Josef Land)

Benthic habitats of Tikhaya Bight (Hooker Island, Franz Josef Land, High Arctic) were studied by using SCUBA equipment (diving quantitative method) and Van Veen grabs. Three main communities have been described. A Gammarus setosus-macroalgae community, probably seasonal, developed above 5 meters depth, had a relatively low diversity with biomass 7.6±0.9 g/m2 and abundance 135±40 ind/m2; a mixed bivalves-amphipods-bryozoan community (Serripes groenlandicus, Mya truncata, Haploops laevis, Alcyonidium disciforme) occured in muddy bottoms with some interspersed boulders between 7 and 30 m depth; it included 101 taxons, had a relatively high biomass 152.3±114.2 g/m2 and abundance 1600±940 ind/m2. A bivalve-dominated community with Musculus niger and Yoldia hyperborean inhabited depth of 67–72 m, included 38 taxons and was characterized by high density of abundance and biomass – 670±295 ind/m2 and 356.1±57.1 g/m2, respectively. Comparison with the previous data obtained 20 years ago at the depth 7–30 m, showed that, possibly, the retreat of the glacier under the influence of increasing temperature in the environment and increased runoff of melt water, washes away clay deposits which led to siltation of the bottom in the bay and caused degradation of kelp, which was partially replaced by invertebrate communities inherent in silted soils.

A new species of the genus Issus Fabricius (Hemiptera: Auchenorrhyncha: Fulgoroidea: Issidae) from Northwestern Algeria

Issus christiani sp. nov. is described from Mostaganem Province of Northwestern Algeria. The new species belongs to “yellowish green” group of Issus species and it is closely related to I. vaucheri Gnezdilov, 2017 according to the structure of male genitalia, but differs by shorter fore wings (length – 4.0 mm) and shorter ventral aedeagal hooks (0.25 times as long as aedeagus). Thus including the new species currently the genus Issus Fabricius, 1803 is documented from the Mediterranean Africa with five species. Key to African species of Issus is given.

Revision of the ichneumon-flies of the genus Ischyrocnemis Holmgren, 1858 with resurrection of the genus Terozoa Förster, 1869 stat. resurr. (Hymenoptera: Ichneumonidae)

Genera Ischyrocnemis and Terozoa (both initially monotypic) have been synonymized by H. Townes (1971) and preliminary placed in the subfamily Metopiinae. The results of molecular analyses (Quicke et al., 2009) did not clarify their systematic position. In this work Terozoa Förster, 1869 gen. resurr. (=Parablastus M. Constantineanu, 1973, syn. nov.) is restored from synonyms and placed into the subfamily Tryphoninae. Terozoa includes three species: type of the genus, Terozoa quadridens Perkins, 1962 (= Parablastus bituberculatus M. Constantineanu, 1973, syn. nov.) and two more species described earlier in ParablastusT. iberica (Kasparyan, 1999) comb. n. and T. anatolica (Gürbüz et Kolarov, 2005) comb. n. The genus Terozoa and species T. quadridens are new records for Russia (North Caucasus, Essentuki). A key to species is provided. Four new Western Palearctic species are in Ischyrocnemis: I. femorator sp. nov. (with two subspecies: Caucasian I.f. femorator subsp. nov. and I. f. turanicus subsp. nov. from Central Asia), I. kotenkoi sp. nov. from the Transcaucasia, I. nigrans sp. nov. from steppes of Eastern Ukraine, Volga region and Kazakhstan, and I. verae sp. nov. from Kopet-Dag. A key to five species of the genus is given. Ischyrocnemis is treated provisionally in Metopiinae after H. Townes (1971), G. Broad and M. Shaw (2005). The characters common for Ischyrocnemis and Metopiinae are discussed: Ischyrocnemis approaches to Metopiinae in having the face and clypeus completely fused and clypeal fovea entirely lacking, that is unusual for most of Ichneumonidae but is typical for many Metopiinae (Acerataspis, Colpotrochia, Periope, Hypsicera, Triclistus, etc.); epipleura very wide (in metopiine present in Colpotrochia, Periope, Hypsicera, Seticornuta, Triclistus, etc.). Unusual for Metopiinae 1st metasomal segment of Ischyrocnemis (without glymmae with spiracles beyond the middle, and strongly narrowed in front of spiracles) found in Periope and in many ways is similar to some other Metopiinae (in genera Apolophus, Colpotrochia).

Our Mother. To mark the centenary of the birth of Gulsyuma Khusyainovna Nuraeva (Urusova) (July 15, 1920 – October 14, 2008)

This article is dedicated to the oldest member of Zoological Institute of the Russian Academy of Sciences and her biography. She devoted her life to the service of science and preservation of collection of osteology department in theriology laboratory. With her own hands she boiled, cleaned and prepared countless exhibit items for storing, expert examination and displaying in the museum. Skillfully reuniting bone fragments found by paleontologists, she assembled numerous skeletal elements and even whole skulls of fossil animals. She was making plaster models from the most precious pieces, so they could be used as emergency copies or sent to the scientists from other institutes and museums in different cities and countries. Many researchers based their scientific articles and monographs on the samples made by G.Kh. Nuraeva. In March 1971 together with the members of the Laboratory of mammals she took part in preparations for the First conference on mammoths and mammoth fauna and in organizing of the exhibition. She also helped in ciphering, packaging and shipping the exhibits for the International hunting exhibit in Budapest (Hungary) in Autumn 1971 and preparing exhibits for “World of a mammoth” exhibition in Japan in 1981 and 1987. She restored a skull and the horns of an Irish elk Megaloceros giganteus, a skeleton of a southern mammoth Archidiscodon meridionalis, the skulls of fossilized bears Ursus deningeri, Ursus spelaeus kudarensis, elements of a skeleton of hoofed animals such as wild ox Bos primigenius and Stenon zebra Equus stenonis, not counting others valuable parts. She took a big part in writing a monograph «Baby mammoths Mammuthus primigenius». G.Kh. Nuraeva was a hard-working person and loved her job. Thanks to that she made an invaluable contribution to increasing of the Zoological Institute collection. Everyone who got to work beside her noted her nimble fingers and her big heart. We will always remember her with fondness and gratitude.
