Calconiscellus karawankianus and P. franzi are East-Alpean species. Trachelipus ratzeburgii and Armadillidium opacum could be apostrophized as Alpine-Central European species. The Sarmata-Caucasian T rathkii and the Ponto-Caucasian Cylisticus convexus are widely distributed in Europe except the Mediterranean. Androniscus roseus has a restricted distribution area, ranging from eastern France to Romania, north to southern Germany. The cosmopolitan A. vulgare is autochthonous in the Mediterranean. Characteristic species of the first order habitats The average number of species per sampling site was 4.53 (std.: 2.32), the maximum and minimum numbers were 12 and 1, respectively. The accumulated number of species ranged between 18 (black locust plantation) and 23 (wetland woodlands) so no differences were found in diversity between the first order habitat classes. In all biotopes, two-thirds of the species (ranging between 57 % and 71%; AVG 65% ± 7) occurred in less than 30% of the samples. By IndVal evaluation, A. zenckeri proved to be a typical species in marshes. No character species was found in the riverine and swamp wetland forests. Typical species of oak woodlands are P. politus (dry oak forests) and L. minutus (fresh oak forests). P. collicola and T. nodulosus revealed characteristic in the black locust plantations. Seven species (A. roseus, С convexus, H. mengii, P. hoffmannseggii, P. scaber, P. pruinosus, P. vulcanius) connect significantly to the synanthropic habitats.
