SOC-DS computer code provides tool for design evaluation of homogeneous two-material nuclear shield

SOC-DS Code /Shield Optimization Code-Direc Search/, selects a nuclear shield material of optimum volume, weight, or cost to meet the requirments of a given radiation dose rate or energy transmission constraint. It is applicable to evaluating neutron and gamma ray shields for all nuclear reactors

The Males of Rhynchomicropteron (Diptera: Phoridae)

The genus Rhynchomicropteron Annandal (1912) has distinctive, myrmecophilous, flightless females. The females of the 17 Oriental species are keyed by Disney & Kistner (1998), supplemented by Disney (1999, 2010). Until Brown (1992) reared R. nudiventer Papp in Thailand, the males had been assigned to the genus Gymnoselia Schmitz (1927). This ‘genus’ contained the type species, R. curvescens (Schmitz 1927) and R. nudicosta (Brues 1907). Neither of these have been linked to their females. Recently Lengyel (2011) has described both sexes of a species from Israel, and reported the presence of this genus in Africa and Australia. The males remain poorly known. The purpose of this paper is to provide a key to the known males, even though most remain unknown and some are given code numbers only until they can be linked to their females

Revision of the Megaselia giraudii and M. densior species complexes of Europe, including ecological notes (Diptera, Phoridae).

Die Megaselia giraudii/densior-Artengruppe umfaßt 21 beschriebene Arten in Europa. Acht Arten werden neu beschrieben: M. citrinella Buck sp. n., M. glabrimargo Buck sp. n., M. hexanophila Buck sp. n., M. immodensior Disney sp. n. (= M. densior auctt., nec Schmitz), M. labellaspinata Disney sp. n. (= M. septentrionalis auctt., nec Schmitz), M. mimodensior Buck sp. n., M. raruvesiculae Disney sp. n. und M. xanthophila Buck sp. n. Megaselia phoenicura (Schmitz), M. badia Schmitz und M. hayleyensis Disney (alle allein von Männchen beschrieben) werden synonymisiert mit M. quadriseta (Schmitz) (bisher nur bekannt im weiblichen Geschlecht). Viele Individuen, die früher für M. badia gehalten wurden, gehören tatsächlich zu M. densior Schmitz, und M. coulsoni Disney wird mit letzterer synonymisiert. Lectotypen werden festgelegt für M. albicans (Wood), M. densior, M. offuscata Schmitz, M. phoenicura und M. quadriseta, sowie ein Neotyp für M. comosa (Schmitz). Die Männchen von M. rubricornis (Schmitz) und Weibchen von M. correlata (Schmitz), M. haraldlundi Disney und M. parnassia Disney werden erstmals beschrieben. Das mutmaßliche Männchen von M. sanguinea (Schmitz) und wahrscheinliche Weibchen von M. albicans werden ebenfalls zum ersten Mal beschrieben. Die Identität anderer Arten wird aufgeklärt inklusive vier Arten, die nicht zum giraudii/ densior-Komplex gehören (M. nigrescens (Wood), M. opacicornis Schmitz, M. rubida (Schmitz) und M. ustulata (Schmitz)). Ein revidierter Bestimmungsschlüssel für Männchen und ein neuer Schlüssel für Weibchen werden vorgestellt. Dabei wird neuen taxonomischen Merkmalen wie den subkutikularen Sensillen innerhalb des dritten Fühlersegments sowie der Morphologie des weiblichen Ovipositors bzw. Vaginalsklerite besondere Beachtung geschenkt. Für die meisten Arten werden außerdem Informationen zur Biologie mitgeliefert (Brutsubstrate der Larven, Köder-, Farb- und Biotoppräferenzen der Imagines).StichwörterDiptera, Phoridae, Megaselia, taxonomy, rearing, saprophages, bait trap, Europe.Nomenklatorische Handlungencomosa Santos Abréu, 1921 (Aphiochaeta), Neotype; syn. n. of Megaselia giraudii (Egger, 1862)phoenicura Schmitz, 1926 (Aphiochaeta), Lectotype; syn. n. of Megaselia quadriseta (Schmitz, 1918)albicans Wood, 1908 (Megaselia), Lectotype described as Phora albicansbadia Schmitz, 1938 (Megaselia), syn. n. of Megaselia quadriseta (Schmitz, 1918)bayleyensis Disney, 1987 (Megaselia), syn. n. of Megaselia quadriseta (Schmitz, 1918)citrinella Buck, 2001 (Megaselia), spec. n.coulsoni Disney, 1987 (Megaselia), syn. n. of Megaselia densior Schmitz, 1927densior Schmitz, 1926 (Megaselia), Lectotypeglabrimargo Buck, 2001 (Megaselia), spec. n.hexanophila Buck, 2001 (Megaselia), spec. n.immodensior Disney, 2001 (Megaselia), spec. n.labellaspinata Disney, 2001 (Megaselia), spec. n.mimodensior Buck, 2001 (Megaselia), spec. n.offuscata (Schmitz, 1921) (Megaselia), Lectotype described as Phiochaeta offuscataquadriseta (Schmitz, 1918) (Megaselia), Lectotype described as Aphiochaeta lutea var. quadrisetararuvesiculae Disney, 2001 (Megaselia), spec. n.xanthophila Buck, 2001 (Megaselia), spec. n.rata Collin in Wood, 1908 (Phora), Lectotype now a synonym of Megaselia giraudii (Egger, 1862)The Megaselia giraudii and M. densior species groups are revised to include a total of twenty-one described European species. Eight species are new to science: M. citrinella Buck sp. n., M. glabrimargo Buck sp. n., M. hexanophila Buck sp. n., M. immodensior Disney sp. n. (= M. densior auctt., nec Schmitz), M. labellaspinata Disney sp. n. (= M. septentrionalis auctt., nec Schmitz), M. mimodensior Buck sp. n., M. raruvesiculae Disney sp. n., and M. xanthophila Buck sp. n.. Megaselia phoenicura (Schmitz), M. badia Schmitz and M. hayleyensis Disney (all described from males only) are synonymised with M. quadriseta (Schmitz) (previously only known in the female sex). Many specimens previously assigned to M. badia are recognised as being M. densior Schmitz, and M. coulsoni Disney is synonymised with this species. Lectotypes are designated for M. albicans (Wood), M. densior, M. offuscata Schmitz, M. phoenicura and M. quadriseta, and a neotype is designated for M. comosa (Schmitz). The males of M. rubricornis (Schmitz) and females of M. correlata (Schmitz), M. haraldlundi Disney and M. parnassia Disney are described for the first time. The putative male of M. sanguinea (Schmitz) and the putative female of M. albicans are also described for the first time. The recognition of other species is clarified including four species that do not belong to the giraudii/densior complex (M. nigrescens (Wood), M. opacicornis Schmitz, M. rubida (Schmitz), and M. ustulata (Schmitz)). A revised key to males and a new key to females is provided, utilising the novel taxonomic character of the subcuticular sensilla inside the third antennal segment, and giving special attention to the morphology of the female ovipositor and vaginal sclerite. Biological data (breeding substrates of larvae, bait, colour and habitat preference of adults) are reported for most species.KeywordsDiptera, Phoridae, Megaselia, taxonomy, rearing, saprophages, bait trap, Europe.Nomenclatural Actscomosa Santos Abréu, 1921 (Aphiochaeta), Neotype; syn. n. of Megaselia giraudii (Egger, 1862)phoenicura Schmitz, 1926 (Aphiochaeta), Lectotype; syn. n. of Megaselia quadriseta (Schmitz, 1918)albicans Wood, 1908 (Megaselia), Lectotype described as Phora albicansbadia Schmitz, 1938 (Megaselia), syn. n. of Megaselia quadriseta (Schmitz, 1918)bayleyensis Disney, 1987 (Megaselia), syn. n. of Megaselia quadriseta (Schmitz, 1918)citrinella Buck, 2001 (Megaselia), spec. n.coulsoni Disney, 1987 (Megaselia), syn. n. of Megaselia densior Schmitz, 1927densior Schmitz, 1926 (Megaselia), Lectotypeglabrimargo Buck, 2001 (Megaselia), spec. n.hexanophila Buck, 2001 (Megaselia), spec. n.immodensior Disney, 2001 (Megaselia), spec. n.labellaspinata Disney, 2001 (Megaselia), spec. n.mimodensior Buck, 2001 (Megaselia), spec. n.offuscata (Schmitz, 1921) (Megaselia), Lectotype described as Phiochaeta offuscataquadriseta (Schmitz, 1918) (Megaselia), Lectotype described as Aphiochaeta lutea var. quadrisetararuvesiculae Disney, 2001 (Megaselia), spec. n.xanthophila Buck, 2001 (Megaselia), spec. n.rata Collin in Wood, 1908 (Phora), Lectotype now a synonym of Megaselia giraudii (Egger, 1862

FIRST RECORD OF FORENSIC SPECIES CONICERA SIMILIS (Haliday, 1833) (DIPTERA: PHORIDAE) ON EXHUMED RABBIT CARCASSES IN TURKEY

Scuttle fly is often observed in forensic cases especially on buried remains. Two genus of Phoridae is very important for buried remains in forensic cases. One of them is Conicera sp., and its literature is very limited. The aim of this study is to find the Conicera sp. in buried carcasses. Two rabbit carcasses were used as bait in Ankara province of Turkey. The insects collected included Conicera similis (Haliday, 1833) (Diptera, Phoridae), which was recorded for the first time in Turkey after the carcasses were exhumed in 45 day
