Abstract: Duvalius (Biharotrechus) bekchievi Guéorguiev, new species, found in caves and on forest ground in the Strandza Mt., is described and diagnosed. The new taxon is closely related to the West Anatolian D. bortesii Casale et Vigna Taglianti, 1984. Peculiarities of the morphology and ecology determine D. bekchievi Guéorguiev, sp. n. as "unspecialized" in respect to the hypogean environment.

Title: Description of a new genus and a new family, Circumphallidae fam. nov., of the acalyptrate flies (Diptera)

Author: Papp, L.

Author's address: Department of Zoology, Hungarian Natural History Museum and Animal Ecology Research Group of the Hungarian Academy of Sciences, H-1088 Budapest, Baross utca 13, Hungary; E-mail:

Abstract: Circumphallus gen. n. (type species C. significans sp. n.) is described based on a unique male from Vietnam. A monotypic family Circumphallidae fam. n. is established and relationships of the new family with several families of the acalyptrate flies are discussed. The family Pallopteridae is re-defined and it is proposed to be restricted it to the genera Palloptera, Toxoneura, Temnosira and Gorbunia (i.e. Morgea, Aenigmatomyia, Heloparia, etc. are removed from Pallopteridae). The peculiarities of the genus Gorbunia Ozerov are emphasized. Eurygnathomyiidae is re-instated as a separate family. With 32 original drawings and six photos.

Key words: Circumphallidae, Circumphallus, new family, new genus, Pallopteridae, Gorbunia, Aenigmatomyia, Eurygnathomyia, Eurygnathomyiidae, Diptera taxonomy, Oriental Region

Title: The nymphs of Micreremus brevipes (Acari: Oribatida) and complementary remarks on the adult

Authors: Pfingstl, T. and Krisper, G.

Authors' address: Institute of Zoology, Karl-Franzens University, Universitaetsplatz 2, A-8010 Graz, Austria; e-mail:

Abstract: The nymphs of the arboricolous oribatid mite Micreremus brevipes are described in detail. Following characters are considered as specific for the juveniles of this species: 1) darker sclerotized pygidial zone, 2) no setae on genu III in all stages and 3) solenidia φ on tibiae II and IV microcephalic. A comparison with other known immatures of the family Micreremidae indicates that the present placement of Phylleremus and Phylloribatula within this family is not justified. Additionally the legs of the adults of M. brevipes are depicted and characterized for the first time, whereas the existence of porose areas on trochanter III and IV, all femora and tarsi could be demonstrated.

Key words: porose organs, arboricolous, Cymbaeremaeoidea, Licneremaeoidea

Title: Fine scale pattern of true bug assemblages (Heteroptera) across two natural edges

Authors: Torma, A. and Gallé, R.

Abstract: The spatial pattern of epigeic true bug assemblages was studied across natural edges at a forest steppe region in Hungary. Two edges were investigated: a poplar forest - open sand grassland (site one) and a juniper forest - open sand grassland (site two). The abundance and variety of true bugs was sampled by pitfall traps. Altogether 1396 adult individuals belonging to 49 species were collected. Some species occurred exclusively at forest habitats and significant indicator species were found in both forest and grassland habitats. However, distinct Heteroptera assemblages were found only at grasslands. The response of the grassland Heteroptera assemblages to the proximity of the edge differed between the two sites. At site one, an approximately seven-meter wide transition zone could be observed from the grassland into the forest, which was characterized by the dissolution of the grassland true bug assemblage. The species richness decreased significantly toward the edge. At site two, an abrupt change in the structure of the Heteroptera assemblage denoted a sharp boundary near to the edge in the juniper forest. The species richness did not changed toward the juniper edge. We found that the cover of dicotyledonous plants, mosses and lichens, bare soil surface and leaf litter had a significant joint effect on true bug assemblages. The characteristic species of the grasslands responded differently to the edges. Specialist herbivour bugs seemed to be affected more stongly and negatively by edges than generalist herbivorous and predaceous species.

Abstract: One of the causes of decline of farmland birds in Europe is the loss of broods. Here, we investigated if region, cattle grazing intensity, habitat edges and vegetation structure around artificial nests influence predation, the major cause of broods' loss. We placed artificial open ground nests (N = 304) resembling the nests of Skylark (Alauda arvensis), baited by one plasticine and one Quail egg in inside and edge habitats of extensively and intensively grazed grasslands in three regions in Hungary in 2003. Interestingly, none of the three factors (region, grazing intensity, edge effect) had significant effects on brood loss according to the generalised linear mixed model, however, interactions between region and management and among region, management and edge effect were significant. This suggests that the effect of management is not the same in different regions, and edge effect depends on both region and management. We also found that nest predation rate is lower if nests are placed in tall grass and greater vegetation cover. This pattern indirectly supports the negative effects of intensive grazing, which can remove most of the vegetation. Therefore, we suggest that extensive grazing should be favoured to conserve ground nesting birds, however, it is essential to avoid duplicating management regimes from one region to another, due to regional differences in the pattern of survival probability.
