title: Redescription and Relationships of Eucyclops persistens (Copepoda: Cyclopidae) Endemic to the Azov-Black Sea Basin
abstract: The cyclopoids of the Ponto-Caspian region has been discussed in numerous articles and seminal monographs of the late V. I. Monchenko, yet relationships of this peculiar fauna to other regions are still poorly understood. Two subspecies of Eucyclops persistens known from interstitial waters in the Black sea region are redescribed here, based on the type material. Eucyclops persistens persistens (estuary zone of Caucasian rivers) and E. persistens tauricus (wells in Crimea) differ from each other
