Contribution to the Knowledge of Ephemeroptera (Insecta) of the Eastern Black Sea Region

Abstract

This study was carried out in order to contribute to the Ephemeroptera (Insecta) fauna of the Eastern Black Sea region and Turkey. As a result, 2.129 larvae specimens from provinces of the Eastern Black Sea region were collected in 2009, and 26 species belonging to 14 genera from 8 families were determined. Eight of these species are new records for the region, namely Baetis vernus, B. (Nigrobaetis) niger, Procloeon bifidum, P. pennulatum, Rhithrogena savoiensis, Ecdyonurus venosus, Choroterpes picteti, Ephemera vulgata. Moreover, Rhithrogena savoiensis Alba-Tercedor and Sowa, 1987 is a new record for the Turkish fauna. Thus, the number of mayfly species in Turkey increased to 158.
