The influence of altitude on the distribution of harvestmen (Opiliones) and on their species diversity in Slovakia was studied. The data were obtained from the numerous published sources and from the unpublished results of the author’s own research activity. These basic results include the findings of 32 species from 680 localities, located unevenly in all the altitudinal vegetation zones of Slovakia at elevations from 107 to 2100 m a.s.l. The sampling area represents almost all the territory of Slovakia. The harvestmen were collected in a wide scale of various types of indigenous terrestrial biotopes including open land, forest ecosystems, agricultural country and urban habitats. The most of the studied species of harvestmen are distributed in a wide elevation range. The model of the altitudinal trend in the harvestmen species diversity has a shape of the single-peaked curve with the peak between 500 and 600 m a.s.l. The reduced richness of species at lower altitudescould be caused by the intensive agricultural activity in these regions. The range of area altitudinal zones 500–12 000 km2 does not show a significant influence on the species diversity of harvestmen.
Egaenus convexus (C.K. Koch) (Arachnida: Opiliones) jest południowo-wschodnioeuropejskim gatunkiem kosarza, który w Polsce był wymieniany zaledwie z 3 lokalizacji. W pracy przedstawiono informacje na temat nowych stanowisk E. convexus odkrytych w południowo-wschodniej części kraju. Potwierdzono także występowanie tego gatunku na znanym z literatury stanowisku w Zagórzu pod Sanokiem. Prezentowane dane są pierwszymi, po ponad 40-letniej przerwie, informacjami o występowaniu tego rzadkiego kosarza na terytorium Polski
Faunistic, distributional, and taxonomic data for the genus Phalangium Linnaeus, 1758 from the Caucasus are presented. Eight species of the genus have been found in the region. Two new species: P. mcheidzeae from Georgia and P. gorbunovi from Volgograd region, Kalmikiya and Krasnodar region are described, the other six species of the area are P. opilio, P. punctipes, P. armatum, P. staregai, P. bakuense and P. armenicum. Each of them is illustrated, their main diagnostic features are summarized and the occurrence of each species is presented. A key to the species of Phalangium of the region is provided.
The invertebrates (Isopoda, Diplopoda, Pseudoscorpiones, Opiliones) from Mazurian Lake Region were studied. At present 11 species of Isopoda, 15 of Diplopoda, 10 of Pseudoscorpiones and 17 of Opiliones are known from this region.
