New records.

Nom. AITOLOAKARNANIAS: Lake Trichonis, NE rocky and stony shore close to Loutra Myrtias, ca 15 m asl, 38°33'34"N, 21°37'33"E, 09.iii.2012, Radea, Charou, Papadogiannis, Parmakelis.

Remarks .

The species was described by Glöer et al. (2007) from rocks covered by microalgae, at 1m depth in the NE bank of Lake Trichonis.Our specimens were rather scattered and were found north of the locality referred by the latter authors, under stones at 10-30 cm depth. According to Albrecht et al. (2009), Lake Trichonis undergoes several human-induced environmental changes with water level loss and eutrophication being the most serious threats for gastropods living in the littoral zone.
