Bythinella petrosensis View in CoL n. sp. [fig. 2.8]

Material examined: Holotype ( RMNH.MOL.340508) and 1 paratype ( RMNH.MOL.340509) from type locality.

Holotype: 2.9 mm high, 1.8 mm broad from type locality.

Paratypes: 1 paratype from type locality, 2.0 mm high and 1.3 mm broad, 4 (dry) in coll. Robert Reuselaars (no. 682).

Locus typicus: Spring 5-6 km Se of Aghios Petros, Parnon mountains, Peleponnesos, Greece at 1.105 meters altitude ( Figure 10 View Figures 10-14 ), 37° 17' 36.115787'' N 22° 35' 30.35337'' E, 24.09.2010 Robert Reuselaars leg. GoogleMaps
