Remarks.

Radomaniola was proposed by Szarowska (2006) as a replacement name for the genus Orientalina (Radoman, 1978). According to Radoman (1983), the Balkan species Orientalina curta ( Küster, 1852) may be divided into a few subspecies on the basis of shell properties and the same author reported the presence of the subspecies Orientalina curta albanica Radoman, 1973 from the area of Ioannina. However, the shell dimensions of the specimens we collected from localities of Aitoloakarnania and Ioannina, (shell height: 1.90-3.65 mm, shell width: 1.20-1.95 mm, aperture height: 0.85-1.30 mm, aperture width: 0.70-1.20 mm) are similar to those of Orientalina curta curta ( Küster, 1852) (shell height: 2.31-3.23 mm, shell width: 1.39-1.93 mm, aperture height: 0.92-1.30 mm, aperture width: 0.84-1.18 mm) reported by Radoman (1983).

Recently, Falniowski et al. (2012) analyzed molecular data from populations of the Radomaniola / Grossuana group collected from several localities of Greece and other countries of Balkan Peninsula. Two of the Greek localities were "spring in the city centre of Thermos, NE of Trichonida Lake" and "springs of Louros". In the Bayesian tree based on COI sequences provided by Falniowski et al. (2012), the specimens from these localities belong to the genus Radomaniola s. stricto. The above authors refer to the specimens from Thermos as " Trichonia kephalovrissonia " in the Bayesian tree. This fact indicates that Trichonia kephalovrissonia Radoman, 1973 [ Schütt (1980) considers this taxon as a synonym of Semisalsa steindachneri (Westerlund, 1902) (= Heleobia (Semisalsa) steindachneri (Westerlund, 1902)] should be assigned to Radomaniola kephalovrissonia (Radoman, 1973). In the Bayesian tree mentioned above, the specimens from Louros seem to be close to Radomaniola montana (Radoman, 1973) and rather far from Radomaniola curta curta ( Küster, 1852) and other Radomaniola curta ( Küster, 1852) subspecies.

Despite the fact that our sampling localities (Fig. 1) are situated very close to those of Falniowski et al. (2012), we consider that all specimens collected from Aitoloakarnania and Ioannina belong to Radomaniola curta as long as only their morphological and anatomical characters have been examined and no molecular data are available.
