The Ant Fauna (Hymenoptera: Formicidae) of North-West German Calluna Heathlands. - From 1980 through 1988, the ant fauna of several NW-German sandy heathlands, some wet heaths and of typical accompanying and bordering biotopes (sandy grassland, pine forest) was studied using a variety of sampling techniques.  As expected, a large number of species occurred, especially on dry heathland.  The 35 ant species recorded on the sites include one first record for the FRG (Lasius carniolicus (MAYR)) and 3 species not as yet reported for the NW-German lowlands (Leptothorax nylanderi (FÖRST.), Strongylognathus testaceus (SCHENCK), Tapinoma ambiguum EM.), as well as 3 species which could not be shown to be indigenous in either of the studied biotopes.  Faunistical and ecological observations of the Formicidae recorded are compared with literature data.  The ant communities of dry Calluna heathlands clearly differed in composition from those of wet heaths and pine forests.  Apart from limitations involved in the present study, the influence of important factors, such as soil moisture, vegetation pattern and the geographic situation of the sites, on the ant fauna of sandy Calluna heathlands is evaluated.

A new species of the genus Actocharis Fauvel 1869 from Greece: Actocharis cassandrensis n. sp. (Col.: Staphylinidae). - Actocharis cassandrensis n. sp., a shore-inhabiting staphylinid collected on the Kassandra peninsula, Greece, is described.  Differential characters allowing separation from A. marina Fauvel, the only valid species of Actocharis Fauvel hitherto known, are pointed out and illustrated.

Zur Käferfauna von Buchfinkennestern. - An investigation of altogether 205 nests of Fringilla coelebs L. in the surroundings of Osnabrück, Lower Saxony, yielded 29 species of Coleoptera, the vast majority of which can be considered secondary or accidental inhabitants of this habitat.  The few nidicolous species recorded were present only in a low proportion of the nests.

The rove beetle fauna (Coleoptera: Staphylinidae) of a complex of urban habitat islands in Hannover (FRG). - 3rd contribution to the faunistics and ecology of the Staphylinidae of Hannover. - From 1989 to 1992 the staphylinid fauna of a complex of urban biotopes including grasslands and copses was studied by means of pitfall traps and with special reference to island ecology.  Altogether about 4400 adult rove beetles and almost 900 larvae belonging to 136 species were sampled.  An additional faunistical investigation of the burrows and nests of small mammals and ants, repectively, yielded a further 14 species.  The staphylinid cenoses are characterized according to the habitat requirements of some of the dominant species.  As expected, species richness was much lower on small and isolated habitat islands than on larger, less isolated plots.  Based on studies of wing length and flight muscle development the staphylinids recorded on the site are assigned to 5 different categories.  A qualitative analysis revealed only little differences between the sites, whereas the populations of some of the poly- or dimorphic species, especially Lathrimaeum atrocephalum (Gyll.) and Xantholinus linearis (Ol.) showed considerable variation with regard to the proportions of beetles capable of flight in relation to size and/or degree of isolation of the plots.  The results for Oxypoda abdominalis, in contrast, were not in agreement with the predictions derived from island ecology.  The phenology of this species is outlined and illustrated.

The Bionomics of Xantholinus rhenanus COIFF. and other soil-dwelling Xantholininae (Col., Staphylinidae) in Northwest Germany. - From 1981 to 1990 field studies on the staphylinid fauna of Calluna-heathlands as well as of various other biotopes in Northwest Germany were carried out using pitfall traps, directly quantifying methods (KEMPSON-extractions), photoeclectors and window traps.  In the course of these studies a considerable amount of ecological and biological data was collected for Xantholinus rhenanus COIFF., a staphylinid especially abundant in heathlands, as well as for 9 further soil-dwelling species of Xantholininae: X. linearis (OL.), X. tricolor (F.), X. jarrigei COIFF., X. laevigatus JAC., X. longiventris HEER, Gyrohypnus scoticus JOY, Othius myrmecophilus KIESW., O. melanocephalus (GRAV.) and O. punctulatus (GZE.). Observations concerning the habitat requirements of the species are compared with literature data. Apart from O. myrmecophilus, whose reproductive period lasts almost through-out the year, all the Xantholininae investigated are univoltine.  The adult life expectancy is less than a year; only a small proportion of the Othius-populations may live longer.  The seasonal activity dynamics of the adults,  the life-histories and, in some species, the imaginal and larval density dynamics are presented. In both X. rhenanus and X. linearis the sexes differ with regard to locomo-tive activity and life-span; the males are considerably more active in late autumn and winter than the females and live much shorter.  Oviposition takes place in spring, under suitable weather conditions apparently even as early as late autumn and winter; the larvae develop in spring and summer.  In spite of the great similarity in their phenology and other biological properties both species were found to coexist on several sites. X. tricolor, X. jarrigei and X. laevigatus have a similar phenology, all of them hibernating as larvae and reproducing in summer, but are segregated with regard to habitat requirements and/or body size.
X. longiventris and G. scoticus have their egg-laying period in spring and summer and hibernate as adults.  In contrast to all the other Xantholininae studied X. longiventris may change biotopes for hibernation. Studies of the alae and the flight-muscles as well as the capture results from window traps and photoeclectors showed that the majority of the species are rarely capable of flight and consequently have little dispersal power.  Only in X. longiventris and G. scoticus higher proportions of macropterous specimens with flight muscles were recorded.

The rove beetle fauna of xerothermous biotopes of Southern Lower Saxony (Col.: Staphylinidae). - From 1984 to 1990 the staphylinid fauna of 4 xerothermous localities in the south of Lower Saxony, Germany, was studied mainly with pitfall traps.  Altogether 208 species were recorded, a large number of them typical thermophilic inhabitants of such biotopes and/or reaching the northernmost limit of their distribution area in this region.  Preliminary inspections of hind wing length revealed that a considerable proportion of the indigenous epigeic staphylinidae are partially or completely incapable of flight.  Dissections of the female gonads, studies of hind wing length and flight muscle development as well as trapping data of adults and larvae provided bionomic details for some of the dominant species.  The records of a number of very rare staphylinids are considered under faunistical and ecological aspects.  A comparison with the staphylinid faunas of xerothermous biotopes in other German localities revealed a high degree of similarity.  The rove beetle communities of the study areas are evaluated with regard to their adaptive properties as well as their relevance for nature conservation.

Records of ants in Southern Lower Saxony (Hym.: Formicidae). - Several pitfall trap studies as well as excursions were carried out primarily in xerothermous localities of Southern Lower Saxony, Germany, a region hitherto almost completely neglected myrmecologically.  The material yielded a number of ant species generally believed to be rare.  Some of them have as yet not been recorded from Lower Saxony, Lasius sabularum not even from the whole of West Germany. The reasons for the "rareness" of some of the species are discussed with particular reference to the German Red Data Book.

A new species of the genus Stenus from Central Europe: Stenus contumax spec. nov. (Col.: Staphylinidae). - Stenus contumax n. sp., so far only known from several urban habitats in Hannover as well as from Hamburg and Lübeck, NW Germany, is described.  Differential characters allowing separation from related species of the Stenus pusillus group are pointed out and illustrated.

Über Sunius fallax (LOKAY, 1919) (Col., Staphylinidae). - In order to clarify the identity of Sunius fallax (LOKAY) the type series was examined. The synonymy of S. austriacus (COIFFAIT) with S. fallax is confirmed.  S. fallax sensu COIFFAIT is regarded as a new species closely related to S. melanocephalus (F.): S. anatolicus n. sp..  The male genitalia of the taxa treated in the study as well as the male sternite VIII of S. fallax are figured.
