A. graeca has been reliable recorded from Albania, Croatia and Greece. B. chalybata has been reliable recorded from Austria, Belgium, Bulgaria, Czech Republic, Denmark, England, Finland, France, Germany, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Roumania, Russia, Slovakia, Sweden, Switzeland. A. graeca and B. chalybata, known as European species, are new records for the Turkish Fauna. In this study, the female ofA. graeca and the female ofB. chalybata are presented and photographs of two species are accompanied. Distribution of these species treated is briefly discussed.展开更多
