Type material. Syntype, SL: 5 mm, MD: 1.5 mm, Zboriv ( Ukraine), illustrated in Friedberg (1914: pl. 20, fig. 18) .

Discussion. Friedberg (1914) illustrated a fragmentary specimen with weakly convex whorls, moderately incised suture and weak, orthocline axial lamellae and relatively narrowly ovate aperture. Although he formally established a new species, his intention was rather to find a new name for the species, which was erroneously identified by Dubois de Montpéreux (1831) as Scalaria pseudoscalaris . For this very specimen, d’Orbigny (1852) had already introduced a new name Scalaria duboisiana [see Hirtoscala duboisianum (d’Orbigny, 1852) ]. In 1928, Friedberg noted that the specimen illustrated by him in 1914 was unidentifiable and illustrated another specimen, which he thought to be closer to the one depicted by Dubois de Montpéreux (1831). This new specimen in Friedberg

(1928: pl. 38, fig. 22) is surely not conspecific with the specimen from (1914) and is also quite different from the illustration in Dubois de Montpéreux (1831) but represents Parviscala lacinia sp. nov. Therefore, the status of ‘ Scala ’ duboisi Friedberg, 1914 remains dubious.

Paleoenvironment. Shallow marine, inner neritic.

Distribution in Central Paratethys. Badenian (Middle Miocene): Polish-Ukrainian Fore-Carpathian Basin: Zboriv ( Ukraine) ( Friedberg 1938).
