Remarks.

Graecoanatolica vegorriticola was initially described as Hydrobia vegorriticola by Schütt (1962) from Lake Vegorritis and, according to Radoman (1983), the small island nearby the north bank of the lake, not far from Arnissa town, is the type locality of this species. The species was known from Lake Vegorritis and Lake Petron ( Schütt 1962). Reischütz and Stummer (1990) and Hemmen and Reischütz (1996) report the presence of this species in the waterfalls of Edessa town, Central Macedonia in 1979, 1987 and 1995.

According to Schütt (1985), the abundance of Graecoanatolica vegorriticola used to be very high in the stony bank of Lake Vegorritis. Later on, Szarowska (2006) reported that only empty shells were found in Vegorritis in 2003. Moreover, Albrecht et al. (2006) found neither alive nor empty shells in 2005.

We found a low abundance population of Graecoanatolica vegorriticola on the banks of Lake Vegorritis south of Arnissa town. Furthermore, two high abundance populationsof Graecoanatolica cf. vegorriticola with many mature individuals were discovered in Livadia and Orchomenos, Central Greece, ca 270 km away from the type locality of Graecoanatolica vegorriticola .

COI sequence data generated from specimens that have been collected from Lake Vegorritis, Livadia and Orchomenos were used to elucidate the taxonomic status of the populations inhabiting the latter two localities. In total, we obtained eight COI sequences of Graecoanatolica vegorriticola specimens from Lake Vegorritis, two sequences of Graecoanatolica from Livadia and six sequences from Orchomenos (Table 1). The COI sequence divergence separating specimens from these populations and those of Graecoanatolica vegorriticola from Lake Vegorritis is 1.7%. The two newly discovered localities are heavily influenced by tourism and agriculture.

During the field survey, we devoted significant effort in finding and collecting alive specimens of the other Balkan species of this genus, Graecoanatolica macedonica , in the Greek part of Lake Dojran. Unfortunately, only empty shells (some of the specimens looking to have recently died) were retrieved.
