Etymology: The new species is named after the type locality Kastalia Spring in Delphi.

Description:

Shell: The shell is ovate cylindrical with a small and flat apex. The 4.5-5 whorls are convex with a deep suture. The body whorl takes about 0.7 of shell height. The aperture is ovate and slightly angled at the top. The peristome is sharp, somewhat thickened at the columella. The umbilicus is closed. The shell is 2.5- 2.8 mm high and 1.6-1.7 mm broad.

Differentiating characters: The length to width ratio of the new species (1.65) is between the higher and more slender B. charpentieri ( Roth, 1855) from Attica (2.2) and B. eleousae n. sp. from northern Parnassus Mountains (<1.55).
