Remarks.

Pseudoislamia balcanica is an endemic species previously known only from its type locality, the NE rocky banks of Lake Trichonis near Myrtia ( Radoman 1983). Szarowska (2006) considers this species to be extinct. In 2007 and 2008, two small populations were found near Myrtia by Albrecht et al. (2009). Our sampling revealed that although Pseudoislamia balcanica forms small sized populations,it is more widespread than previously thought and thrives both in lentic and lotic waters.
