Type material. Lectotype designated herein: specimen illustrated in Friedberg (1914, pl. 16, fig. 17), SL: 12.5 mm, MD: 5.0 mm, State Museum of Natural History of the National Academy of Sciences of Ukraine in Lviv (formerly Muzeum Dzieduszyckich). It was not possible to trace the type material.

Type locality. Kuncha (Kuńcza) ( Ukraine) .

Stratigraphy. Middle Miocene, Sarmatian (Volhynian).

Revised description. Small, solid, shell with high, conical spire. Protoconch unknown. Teleoconch of 10 whorls. Apical angle ranging around 35°. Suture moderately incised, straight or slightly undulating. Later whorls with two spiral rows of wide spaced beads at adapical suture and slightly above abapical suture. Spiral sculpture weak. Aperture ovoid, strongly oblique. Outer lip well rounded, slightly thickened. Anal canal narrowly incised; Columella deeply excavated, smooth. Inner lip callus sharply delimited from base, moderately thickened; parietal callus strongly thickened forming broad parietal pad. Siphonal canal strongly deflected to the left, short, moderately wide, deeply incised and deeply notched. Last whorl with about six orange stripes.

Discussion. This species is restricted to the Volhynian of the Ukrainian Fore-Carpathian Basin and the adjacent Moldavian Platform. It differs from Lampanella obliquistoma ( Seguenza, 1880) in its high spire and elongate outline. Lampanella maeotica ( Karlov, 1932) might be closely related, which lacks the prominent beads along the adapical suture.

Distribution. Restricted to the Volhynian of the Ukrainian Fore-Carpathian Basin and the adjacent Moldavian Platform.
