Review of subfamily Diplazontinae (Hymenoptera: Ichneumonidae) from South Korea with six unrecorded genera and a new species

Of the 16 genera of the subfamily Diplazontinae occurring in the Eastern Palearctic region, 11 genera are recognized from South Korea. Specifically, four genera (Campocraspedon Uchida, Diplazon Nees, Syrphoctonus Förster and Woldstedtius Carlson) are previously recognized from South Korea, whereas the other seven genera are recorded from this country for the first time.

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: 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.

Diverse middle Ordovician palaeoscolecidan worms from the Builth‐Llandrindod Inlier of central Wales

Abstract: Palaeoscolecidan worms are rare, Early Palaeozoic fossils with uncertain affinities within the Ecdysozoa. They are locally abundant in the Cambrian and scattered in the Early Ordovician, but very sparse thereafter. Forty‐four specimens have been collected from the Middle Ordovician of the Builth‐Llandrindod Inlier of Mid Wales and include well‐preserved material assigned to seven new genera, with four additional species in open nomenclature. An additional specimen from the Arenig Pontyfenni Formation of South Wales is also described in open nomenclature. The total demonstrates much greater palaeoscolecid diversity than hitherto suspected for this time. The specimens are preserved as cuticle fragments in shales and siltstones, often of submillimetre size but in many cases with excellent preservation. The level of detail preserved in some is equal to that found in Cambrian phosphatized faunas. The new approach to collecting, and the recognition that this material can yield taxonomically useful information, opens new avenues for palaeoscolecidan research in siliciclastic environments. The new taxa are the following: Radnorscolex bwlchi gen. et sp. nov., Aggerscolex murchisoni gen. et sp. nov., Bullascolex inserere gen. et sp. nov., Wernia eximia gen. et sp. nov., Ulexiscolex ormrodi gen. et sp. nov., Pluoscolex linearis gen. et sp. nov. and Loriciscolex cuspidus gen. et sp. nov. The high diversity, and the taxonomic separation from known groups described primarily from Cambrian carbonates, implies that palaeoscolecidans either diversified significantly during the Ordovician or were taxonomically segregated between carbonate and siliciclastic settings. Palaeobiological findings also include confirmation that some palaeoscolecid basal cuticles were solid and others reticulate, plates (and platelets) could form by lateral accretion, plates were in part primarily phosphatic and in part organic and that in at least some groups, platelet secretion occurred external to plate secretion.
