New records of the sea anemone <Emphasis Type="Italic">Ptychodactis patula</Emphasis> Appellöf, 1893 (Anthozoa: Actiniaria) in the northern and far eastern Seas of Russia

Twenty-two samples of a rare sea anemone Ptychodactis patula having an unusual structure were found in the collection of the Zoological Institute (Russian Academy of Sciences, St. Petersburg). This species was previously referred to the small order Ptychodactiaria, which included only three species. P. apatula was known only from the coasts of Norway (the type locality), Iceland, and the Bering Strait. Our samples greatly exceed the materials thus far published, both in the number of specimens and their places of discovery.     

Grass Flies (Diptera,Chloropidae) of Crimean Peninsula

The fauna of grass flies (Diptera: Chloropidae) of the Crimean Peninsula is reviewed for the first time. The study is based on examination of the collection of the Zoological Institute, Russian Academy of Sciences (St. Petersburg), which includes the material collected in Crimea by the authors, the collections of the Zoological Museum of the M. V. Lomonosov Moscow State University and V. I. Vernadsky Crimean Federal University (Simferopol). The annotated list includes 92 species in 34 genera and three subfamilies. Most of the species (61) are recorded from Crimea for the first time. Six species, Chlorops horridus Becker, Ch. puncticornis Loew, Dicraeus (Oedesiella) beschovskii Nartshuk, Lasiosina chandleri Ismay, Meromyza meigeni Nartshuk and Oscinimorpha longirostris (Loew) are recorded for the first time from Russia and Eastern Europe. The characters for distinguishing Oscinimorpha arcuata Duda from O. longirostris (Loew), i.e., the structure of head and the male genitalia, are provided. The boreo-montane species Oscinella vastator (Curtis) and Meromyza curvinervis (Zetterstedt) are found on the Chatyrdag Mountain and Yaila (mostly forestless plateau in the Crimean Mountains). Species with southern European, Mediterranean and Macaronesian-Mediterranean ranges were recorded mostly on the South Coast of Crimea. The Crimean fauna of Chloropidae is compared with the faunas of Sardinia and Turkey.

A new genus is erected for Hysteropterum boreale Melichar, 1902 which is redescribed. Lectotype is designated in the type series of the species deposited in the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia). Photographs of the female (paralectotype) and drawings of the male (lectotype) genitalia are provided.     

A revision of the grass flies from E.A. Eversmann’s collection with description of a new species of the genus <Emphasis Type="Italic">Chlorops</Emphasis> Meigen (Diptera,Chloropidae)

E.A. Eversmann’s collection of grass-flies (Chloropidae) deposited at the Zoological Institute of the Russian Academy of Sciences, St. Petersburg, is revised. The total of 22 species are recorded from Kazan (10 species of the subfamily Oscinellinae, 12 species of the subfamily Chloropinae), and 4 species, from Orenburg and Orenburg Province. Almost all the species, except for the agricultural pests, are recorded for the respective regions for the first time. A new species, Chlorops eversmanni sp. n., is described from Kazan.     

Contribution to Systematics of the Genus <Emphasis Type="Italic">Astiphromma</Emphasis> Förster (Hymenoptera,Ichneumonidae: Mesochorinae) from Russia and Adjacent Countries

Material of the genus Astiphromma Förster (Hymenoptera, Ichneumonidae: Mesochorinae) from Russia and adjacent countries in the Zoological Institute, St. Petersburg has been examined. 25 species were identified, 14 of which are new records to the Russian fauna, and 10 are new to the Eastern Palaearctic Region. Four species are new to science: Astiphromma (Astiphromma) flavofaciessp. n., A. (A.) minimumsp. n., A. (A.) paradorsalesp. n., and A. (A.) styleatorsp. n. A new synonymy is established: Astiphromma (Astiphromma) albitarse (Brischke, 1880) = A. punctatum Uchida, 1933, syn. n. For Astiphromma japonense Lee, 1992 a hitherto unknown female is described.     

Revalidation of the Eggvin lumpsucker <Emphasis Type="Italic">Eumicrotremus eggvinii</Emphasis> (Cyclopteridae) and its new finding near Franz Josef Land (Barents Sea)

The species status of a rare species Eumicrotremus eggvinii from the family Cyclopteridae has been revalidated. Some authors considered its specimens as males of close species E. spinosus. In the Zoological Institute collection, males of E. spinosus that are morphologically similar with females of this species have been found. This is evidence of absence of sexual dimorphism in E. spinosus. In new samplings from waters of the Franz Josef Land archipelago (Barents Sea), a specimen of E. eggvinii was found and described. The opinion of some authors that individuals of E. eggvinii represent males of E. spinosus is refuted. A new finding widens the species area to the northeastern limits of the Barents Sea. The number and character of distribution of bone plaques remain reliable taxonomic characters.     

On establishing of a weevil <Emphasis Type="Italic">Otiorhynchus smreczynskii</Emphasis> Cmoluch, 1968 (Coleoptera,Curculionidae) in St. Petersburg (Russia)

Otiorhynchus smreczynskii Cmoluch was first found in St. Petersburg in 2011 and in 2015 was common all over the city on lilac (Syringa spp.).     

On Records of Three Additional Species of the Weevil Genus <Emphasis Type="Italic">Otiorhynchus</Emphasis> Germ. (Coleoptera,Curculionidae: Entiminae) on Lilacs (<Emphasis Type="Italic">Syringa</Emphasis> L.) in St. Petersburg

In the summer and autumn of 2017, two mostly Southeastern European weevils Otiorhynchus albidus Stierlin, 1861 and O. asphaltinus Germar, 1824, and also O. rotundus Marseul, 1872, previously unknown from Russia, were found in numbers on Syringa vulgaris L. and S. josikaea Jack. in St. Petersburg. New data on the distribution of O. smreczynskii and a key for differentiation of O. rotundus, O. smreczynskii and closely allied to the latter O. ukrainicus Korotyaev, 1984 from southeastern Ukraine and eastern Crimea are reported.     

Estimation of biotechnological potential and clarification of taxonomic status of <Emphasis Type="Italic">Parietochloris</Emphasis> genus microalgae (Trebouxiophyceae) from the CALU collection

Morphological, biochemical, and molecular genetic studies of green microalgae from the collection of cyanobacteria, algae, and algal parasites of St. Petersburg State University (CALU) (presumably belonging to the Parietochloris genus) were conducted in order to estimate biotechnological potential and clarify the phylogenetic position. It was determined that the studied strains have a close relationship to two genera from different classes (Lobosphaera (Trebouxiaceae) and Deasonia (Actinochloridaceae)) and can be of biotechnological interest as producers of valuable polyunsaturated fatty acids (especially arachidonic, linoleic, and α-linolenic).     

<Emphasis Type="Italic">Dencyrtus</Emphasis> gen. nov. (Hymenoptera,Chalcidoidea, Encyrtidae) from the Late Eocene Danish Amber

Based on two females from the Danish amber collection of the Zoological Museum of University of Copenhagen, Dencyrtus vilhelmseni gen. and sp. nov. is described. The antennae of the new genus are very similar in structure to that of Eocencyrtus Simutnik, 2001 from the Rovno and Baltic ambers. However, the presence of the filum spinosum on the linea calva of the forewing disc indicates that it belongs to a different subfamily.
