Selected AbstractsNOTES ON GENUS PROCONURA DODD (HYMENOPTERA: CHALCIDIDAE) FROM CHINA WITH DESCRIPTION OF ONE NEW SPECIES AND ONE NEW RECORD SPECIES,INSECT SCIENCE, Issue 1 2001LIU Chang-ming Abstract This paper deals with the Chinese species of the genus Proconura Dodd. A new species P. eurygena Liu, sp. nov., a new record species P. caryobon(Hanna) and other two species P. asiatica Narendran and P. ishiii (Habu) are described. The holotype of P. eurygena is from Hainan Province. Its main features are: antennae and hind femora brown; vertex long; COL to POL as1:3; scapes reaching front ocellus, almost 3 times as long as pedicel; gaster with basal carinae short and distinctly converging backwards; first tergite of gaster smooth, without puncture. A key to known Chinese species of Proconura is given. Type specimen is deposited in Institute of Zoology, the Chinese Academy of Sciences. [source] The fate of the homoctenids (Tentaculitoidea) during the Frasnian,Famennian mass extinction (Late Devonian)GEOBIOLOGY, Issue 3 2006DAVID BONDArticle first published online: 18 AUG 200 ABSTRACT The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals that are among the most abundant and widespread of all Late Devonian fossils. They were a principal casualty of the Frasnian,Famennian (F-F, Late Devonian) mass extinction, and thus provide an insight into the extinction dynamics. Despite their abundance during the Late Devonian, they have been largely neglected by extinction studies. A number of Frasnian,Famennian boundary sections have been studied, in Poland, Germany, France, and the USA. These sections have yielded homoctenids, which allow precise recognition of the timing of the mass extinction. It is clear that the homoctenids almost disappear from the fossil record during the latest Frasnian ,Upper Kellwasser Event'. The coincident extinction of this pelagic group, and the widespread development of intense marine anoxia within the water column, provides a causal link between anoxia and the F-F extinction. Most notable is the sudden demise of a group, which had been present in rock-forming densities, during this anoxic event. One new species, belonging to Homoctenus is described, but is not formally named here. [source] NOTES ON SOME FORSIUS, TYPES OF ASIAN SAWFLIES (HYMENOPTERA: TENTHREDINOIDEA) WITH DESCRIPTION OF A NEW SPECIES,INSECT SCIENCE, Issue 4 2000WEI Mei-cai Abstract, Some types of E. Asian sawfly species described by Forsius in 1931 are examined. One new species is described based on the paratypes of a species described by Forsius: Eutomostethus forsiusi sp. nov. Three new combinations are provided: Nesoselandria annamitica (Forsius 1931) comb. nov., Birmindia gracilis (Forsius 1931) comb. nov. and Eutomostethus sikkimensis (Forsius 1931), comb. nov., two synonyms are proposed: Birmindia gracilis (Forsius 1931) =Birmindia albipes Malaise 1947, syn. nov. and Indotaxonus tricoloricornis (Konow, 1898) =Conaspidia dubiosa Forsius 1931, syn. nov. [source] New Fossil Beetles of the Family Ommatidae (Coleoptera: Archostemata) from the Jehol Biota of ChinaACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2006TAN Jingjing Abstract, A new genus with one new species and five new species of genus Amblomma of fossil ommatids are described and illustrated: Euryomma tylodes gen. et sp. nov., Amblomma cyclodonta sp. nov., Amblomma miniscula sp. nov., Amblomma porrecta sp. nov., Amblomma eumeura sp. nov., and Amblomma protensa sp. nov. All of them were collected from the Upper Jurassic or Lower Cretaceous Yixian Formation of western Liaoning, China. A key to the species of Amblomma is given. The wide epipleural space shows that Euryomma may be a primitive genus in Ommatidae. Many different species of Amblomma occurred within the same sedimentary horizon in this area could be environmental changes caused by frequent volcanic activities during the deposition of the Yixian Formation.
