• Alopia pomatias albicostata (M. Kimakowicz, 1894)
• Alopia pomatias pomatias (L. Pfeiffer, 1868)

Description

The length of the shell attains 14 mm, its diameter 4 mm. ^[1]

(Original description of Balea cyclostoma was in Latin) The solid, sinistral shell is deeply fissured and spindle-shaped with a turreted form, exhibiting a rich dark violet-brown coloration. Its spire tapers regularly toward a slightly pointed, blackish-brown apex. The suture is whitish, with a papillary, thread-like appearance. There are nine slightly convex whorls, with the body whorl somewhat compressed at the base and barely detached at the front, featuring distinctive white ribbing. The oblique aperture is pear-shaped to rounded, while the upper lamella is small and the lower lamella is deeply set. The continuous peristome is expanded and flattened, edged with a clean white lip. ^[2]

Distribution

This species occurs in Romania.
