Material examined. Above Kayabasi , south Sögüt , Ak Daglari , 29°51'E / 36°57'N , 6-V-97, 1♀ ( Vinçon coll.), Rize , Ovitdagi gecidi, S. slope of the pass, 2600 m a.s.l. , 40°48'E / 40°37'N , 12-V-97, 4♂ ( Vinçon coll.) . Affinities. C. arensis belongs to the pedestris group that has a mainly central Asian distribution ( Zwick & Sivec 1980 ). Ecology. Orophilic, stenothermic cold water species, occurring in fast flowing and rather large mountain streams, mainly between 1000 and 2000 m a.s.l. ( Zhiltzova 1964 ) and up to 2600 m in the Eastern Pontic Mountains. The adults emerge in spring (II- VI) and are often captured on snow. Distribution. Caucasus, Armenia and Anatolia . In Anatolia , it was only known from the Ankara region ( Zwick 1975 , Kazanci 1982 ), but its distribution extends over the whole peninsula, from the eastern Pontic Mountains up to the south-western coast (Ak Daglari) ( Fig. 12 ).
