Mazandaran , Pool to Kojoor , 27 July 2014 , leg. G.M. Kashani , one male ( PCGMK 1938 ). Remarks. Schmalfuss (1986) reported P. obsoletus from one locality in northern Iran ( Fig. 1 ) and later ( Schmalfuss 1992 ) suggested the separation of Iranian population from the main distribution area of the species has been occurred by the ecological barriers (steppe) or climate factors (e. g. temperature). In the present study, this species was found in just one locality ( Fig. 1 ) indicating presumably the restricted distribution of the species in northern Iran . Distribution. Central Italy ; Yugoslavia ; Greece ; southwestern Turkey ; Cyprus ; Lebanon ; northern Syria ; Crimea; northern Iran .
