A new subfamily of ichneumon wasps (Insecta: Hymenoptera: Ichneumonidae) from the Upper Cretaceous of the Russian Far East

A new subfamily of ichneumon wasps, Labenopimplinae subfam. nov. (Ichneumonidae), is described from the Cenomanian Ola Formation of the locality Obeshchayushchiy, Magadan Region, Russian Far East. The subfamily is highly diverse morphologically and combines characters of the Labeninae and Pimplinae. It includes 11 new species described in five new genera: Labenopimpla rasnitsyni gen. et sp. nov., L. kasparyani sp. nov., Armanopimpla zherikhini gen. et sp. nov, Ramulimonstrum intermedium gen. et sp. nov., Rugopimpla vulgaris gen. et sp. nov., R. fallax sp. nov., R. angusticella sp. nov., R. macra sp. nov., R. matrona sp. nov., Micropimpla lucida gen. et sp. nov., and M. obscura sp. nov. Also described is a new monotypic genus, Tryphopimpla xoridoptera gen. et sp. nov., which combines characters of the Tryphoninae, Pimplinae, and Xoridinae and cannot be currently placed into any of the known subfamilies. The population of fossil ichneumon wasps at this locality is distinctly dominated by females.     

New data on trematosauroid labyrinthodonts of Eastern Europe: 2. <Emphasis Type="Italic">Trematosaurus galae</Emphasis> sp. nov.: Cranial morphology

The cranial morphology of a new species of the genus of Trematosaurus, T. galae sp. nov., represented by fragmentary specimens from the Lower Triassic Donskaya Luka locality (Volgograd Region), is described in detail. The diagnosis of the genus Trematosaurus is amended.     

New data on trematosauroid labyrinthodonts of Eastern Europe: 3. <Emphasis Type="Italic">Qantas samarensis</Emphasis> gen. et sp. nov.

Based on fragmentary remains (incomplete lower jaw and premaxilla) from the Lower Triassic Kamennyi Dol locality (Kamennyi Yar Formation, Rybinskian Horizon) of Obshchii Syrt (Samara Region) and a number of specimens from the same region, a new genus and species of trematosauroid temnospondyls, Qantas samarensis gen. et sp. nov., is described. It displays a mosaic combination of typical benthosuchid and trematosaurid characters, remaining in general structure of the lower jaw at the benthosuchid evolutionary level, so that a new benthosuchid subfamily, Qantasinae subfam. nov., representing an isolated lineage, is established. Based on the cranial remains of trematosaurid temnospondyls from the Cynognathus Zone of South Africa, which were previously described by Shishkin and Welman (1994), a new trematosaurine genus and species, Trematosuchoides africanus gen. et sp. nov., is established.

On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora.

The sutural ontogeny of this genus, which is examined for the first time for two species of the genus, supports the high taxonomic rank of praeglyphioceratids. This family is mostly related to primitive Prionoceratoidea. A new species, Praeglyphioceras korobkovi sp. nov., is described from the delphinus Zone (Prolobites-Platyclymenia Genozone) of the Aktyubinsk Region of Kazakhstan.     

New conodonts of the genus <Emphasis Type="Italic">Polygnathus</Emphasis> from the Evlanovian and Livnian (Upper Devonian) of the Voronezh Anteclise (central Devonian Field)

New conodont species of the genus Polygnathus (P. krutoensis sp. nov., P. makhlinae sp. nov., P. menneri sp. nov., P. obruchevae sp. nov.) are described from the Evlanovian-Livnian (Upper Devonian) deposits of the Voronezh Anteclise (central regions of the Rassian platform). The ontogenetic series of the new species are presented.

Morphological and Molecular Diversity of the Neglected Genus Rhizomastix Alexeieff, 1911 (Amoebozoa: Archamoebae) with Description of Five New Species

The genus Rhizomastix is a poorly known group of amoeboid heterotrophic flagellates living as intestinal commensals of insects, amphibians or reptiles, and as inhabitants of organic freshwater sediments. Eleven Rhizomastix species have been described so far, but DNA sequences from only a single species have been published. Recently, phylogenetic analyses confirmed a previous hypothesis that the genus belongs to the Archamoebae; however, its exact position therein remains unclear. In this study we cultured nine strains of Rhizomastix, both endobiotic and free‐living. According to their light‐microscopic morphology and SSU rRNA and actin gene analyses, the strains represent five species, of which four are newly described here: R. bicoronata sp. nov., R. elongata sp. nov., R. vacuolata sp. nov. and R. varia sp. nov. In addition, R. tipulae sp. nov., living in the intestine of crane flies, is separated from the type species, R. gracilis. We also examined the ultrastructure of R. elongata sp. nov., which revealed that it is more complicated than the previously described R. libera. Our data show that either the endobiotic lifestyle of some Rhizomastix species has arisen independently from other endobiotic archamoebae, or the free‐living members of this genus represent a secondary switch from the endobiotic lifestyle.     

Asiaontsira gen. nov., a new tropical genus of the subfamily Doryctinae (Hymenoptera: Braconidae) from Vietnam and South‐East China

A new genus, Asiaontsira gen. nov., and two new species, A. cucphuongi sp. nov. (type species) and A. cantonica sp. nov., are described from tropical and subtropical areas of South‐East China and North Vietnam. This genus is compared to the closely related Australian Ontsirospathius Belokobylskij, Iqbal and Austin, 2004 as well as the similar and almost cosmopolitan genus Ontsira Cameron, 1900. A key to both species of Asiaontsira gen. nov. is provided.     

Gastropods of the family Aporrhaidae from the Lower Cretaceous of Ulyanovsk, Volga Region

Three new species of the genus Trilemma (family Aporrhaidae), T. polivnense Blagovetshenskiy, sp. nov., T. kremenkense Blagovetshenskiy, sp. nov., and T. tenuicarinatum Blagovetshenskiy, sp. nov., from the Lower Cretaceous of the Volga Region near Ulyanovsk are described. The data on the stratigraphic range of these species are provided.     

A new genus of Elateriform beetles (Coleoptera,Polyphaga) from the Jurassic of Daohugou,China

A new coleopteran genus, Parelateriformius, gen. nov., comprising the species P. communis, sp. nov., P. villosus, sp. nov., P. capitifossus, sp. nov., and P. mirabdominis, sp. nov., is described from Daohugou deposits, Inner Mongolia, China, and is assigned to the infraorder Elateriformia. The systematic position of the new genus within the suborder Polyphaga is discussed.     

First records of the genus <Emphasis Type="Italic">Ulocrinus</Emphasis> miller et gurley (Crinoidea,Cromyocrinidae) from the upper carboniferous beds of the Moscow syneclise and Oka-Tsna Swell

Three new species of the genus Ulocrinus, which is recorded for the first time in the Upper Carboniferous of the Moscow Region, are described. These are U. neverovoensis sp. nov. and U. karchevskyi sp. nov. from the Kasimovian Stage and U. grishini sp. nov. from the Gzhelian Stage. Intraspecific variability and structural variations in arms are considered. The uniserial arm structure is established for the first time in juvenile Ulocrinus. The sequence and causes of the acquisition of biserial arms in cromyocrinids are discussed.
