The endophallic structure of the genus Laius is studied and discussed based on the examination of 19 species from Asia to the Indian Ocean. The structure contains two primary sclerites (named gonoporal piece and ligula), a secondary sclerite on the basal part of the gonoporal piece (named additional sclerite) in some species, and a membranous basal area closely covered with many spines (named spinous area). Five species groups are recognized based on the morphology of the endophallic sclerites. The sympatric species have different body sizes and quite distinguishable endophallic sclerites (= different species group), while the allopatric species have overlapping body sizes and similar endophallic sclerites (= same species group). Three new species are described and six previously known species are redescribed with endophallic sclerites, and the descriptions of endophallic sclerites of the remaining ten species are added. The larva of Laius rodriguesensis sp. nov. is also described. The genus
Nossibeus Evers, 1994 is synonymised with Laius Guérin-Méneville, 1830.
Pocket gopher burrows were sampled from 22 counties within Arkansas to determine the associated faunal composition of three major families of Coleoptera (Histeridae, Leiodidae and Scarabaeidae) commonly associated with pocket gopher burrows. We collected eight species of Histeridae, four species of Leiodidae and eight species of Scarabaeidae from the burrows of Geomys breviceps Baird. Three of the Histeridae were new state records, Geomysaprinus goffi Ross, G. rugosifrons (Fall) and Margarinotus felipae (Lewis). All of the Leiodidae were new state records and one Scarabaeidae was a new state record, Dellacasiellus concavus (Say). The most commonly collected scarab beetles were Cryptoscatomaseter haldemani (Horn) and Geomyphilus insolitus (Brown). The most commonly collected hister beetle was Onthophilus kirni Ross. The Leiodidae were infrequently captured.
This document describes the biological cycle of two species of the genus Corades Doubleday, C. chelonis Hewitson and C. dymantis Thieme. The morphological characteristics of the two species are compared to each other, to other species of Corades and to other members of the subtribe Pronophilina. An outstanding character of the larvae of C. chelonis is the united cephalic horns which differ from the other species of Corades. The hostplant of both species is Chusquea serrulata. Oviposition varies between the two species of the study. Immature stage development takes an average of 147 days for C. chelonis and 150 days for C. dymantis. Both species were raised ex situm in the same life zone. Ethological aspects of the larvae and adults are discussed and compared.
A recent investigation was conducted to assess the threat of insect venom hypersensitivity to deployed U.S. service members operating in the region. In parallel with this study, a checklist of medically important Hymenoptera was assembled from limited fi eld collections as well as a comprehensive review of the literature and information provided by electronic databases. We compiled names of 14 families comprising 396 species of Hymenoptera capable of stinging humans. This is the first such checklist for Afghanistan, and should aid future taxonomic work and provide reference information for public health-related entomology in this region.

Debate exists regarding the number of species of the moon jellyfish (genus Aurelia), a common member of the planktonic community of the coastal shelf seas around the world. Three Aurelia congeners (A. aurita, A. labiata and A. limbata) are currently considered to exist but recent genetic analyses suggested that this is an oversimplification. We analyzed the morphological characteristics of scyphistomae, morphological characteristics of ephyrae and differences in the time span of the strobilation process of Aurelia congeners from 17, 7 and 6 different source populations, respectively, of known species. Morphological characteristics of scyphistomae were similar among the 17 populations but those of ephyrae, such as the shape and form of lappets, were effective discriminators in the 6 cases examined. We recommend identifying species based on differences in 1) the morphological characteristics of scyphistomae and ephyrae (and not only medusae), 2) the genetics of individuals, and 3) the geographical occurrence of the population. This study adds to the growing body of knowledge on scyphozoan scyphistomae and ephyrae, stages of the metagenic life cycle of scyphozoans that have received relatively little study compared to medusae.
Tarr Béla ist der international einflussreichste mitteleuropäische Filmemacher der Nach-1989er-Dekaden – was nicht heißt, dass sein Schaffen allgemein geläufig und regelmäßig zu sehen wäre, ganz im Gegenteil.
Davon abgesehen: Wenn die Leute vom Schaffen Tarrs schwärmen, der Radikalität seiner Ästhetik, dann reden sie in Wirklichkeit eigentlich immer nur von einem Film: Sátántangó (1994), ein rund siebeneinhalb Stunden langes Monument, das damals, noch während seiner ersten internationalen Vorführung bei der Berlinale 1994, zum Axiom einer ästhetischen Spätmoderne akklamiert worden war. Wobei kaum jemand Sátántangó je zu sehen bekam, was daran liegt, dass sich Kinos nur in Ausnahmefällen dazu aufschwingen, solche Normensprenger zu zeigen. Freilich gibt es DVD-Veröffentlichungen; da sieht und hört man zwar was, nur gelebt hat man Sátántangó so nicht. Wie auch, wenn weder der Film selbst atmet noch eine Menschenmasse oder zumindest -menge um einen herum, und man mit ihr? Und darum geht es bei diesem Brocken filmgewordenen Lebens, überhaupt dem Schaffen Tarrs: Die Erfahrung von Gegenwart und Gemeinschaft, Dauer und Raum angelegentlich einer Präsentation schwarzweißer Bilder und einiger weniger Klänge, die mal Worte sind und mal Töne und mal Musik. Sátántangó, dieses Antiepos vom Zerfall einer landwirtschaftlichen Produktionsgenossenschaft in spät- bis postkommunistischen Zeiten, besteht im Wesentlichen aus Plansequenzen, die auch mal zehn, zwölf Minuten lang sein können.
