От тях 4 са нови за гръцката фауна (Paranemastoma aurigerum ryla,Histricostoma drenskii, Dasylobus beschkovi и Mitopus morio). Района наезерото Керкини се явява второто находище в Гърция за следните редкиопилиони: Paranemastoma radewi, C. ornatum, R. balcanica, Lacinius dentiger иOligolophus tridens. За сега няма опилиони, които да са защитени със закон. Но средOpiliones на Керкини интерес в това отношение представляват балканскитеендемити P. radewi, P. a. ryla, Mediostoma strussineri, Carinostoma ornatum, H.drenskii, Graecophalangium atticum, R. balcanica, D. beschkovi и Leiobunum sp.Тези видове се срещат в специфични хабитати и досега са намирани с нискачисленост само в малко на брой находища. Всичко това прави посоченитевидове опилиони изключително уязвими, което налага да се обърнеспециално внимание на тяхната защита и опазване.BIODIVERSITY AND CONSERVATION STATUS OF OPILIONES(ARACHNIDA) OF WETLAND KERKINI (N. GREECE)P. Mitov 1 , G. Ramel 21 Department of Zoology and Anthropology, Faculty of Biology, University of Sofia,8 Dragan Zankov Blvd., 1164 Sofia, Bulgaria. e-mail: pl_mitov@yahoo.com;2 Centre of Ecotourism, Lithotopos, TK 624 00, Serron, Greece.e-mail: mrgordonramel@yahoo.comA report on the results of a research into some aspects of the opilionid fauna of theGreek Nature Reserve associated with Lake Kerkini, known as Wetland Kerkini, ispresented. Lake Kerkini is an artificial lake, created in 1932 on the river Strymonimmediately south of the Greek border with Bulgaria and 80 km north ofThessaloniki. The area was originally an inland delta, a huge marsh where the riverunloaded the debris it had collected on its journey past the Ryla and Pirinmountains of Bulgaria, and as a wetland habitat it was unique in Europe. The areais currently a RAMSAR and NATURA2000 site as well as a Wetland ofInternational Importance for birds. From the areas sampled we recorded 17opilionid species (one was identified to generic level), of which 4 are new for theGreece fauna (Paranemastoma aurigerum ryla, Histricostoma drenskii, Dasylobusbeschkovi, and Mitopus morio). The region of Kerkini is the second in Greecelocality for the follow rare species: Paranemastoma radewi, C. ornatum, R.balcanica, Lacinius dentiger, and Oligolophus tridens. There are no species ofharvestmen protected by law. However among the Opiliones in Wetland Kerkini,interest is drawn to the Balkan endemics P. radewi, P. a. ryla, Mediostomastrussineri, Carinostoma ornatum, H. drenskii, Graecophalangium atticum, R.balcanica, D. beschkovi, and Leiobunum sp. These species inhabit specific habitatsand are found in several sites in low numbers. All this suggests special measures tobe taken for their protection and conservation.149
