Hirtoscala duboisianum (d’Orbigny, 1852)

Hirtoscala duboisianum (d’Orbigny, 1852) species inquirenda

Scalaria pseudoscalaris Broc.— Dubois de Montpéreux 1831: 43 View in CoL , pl. 2, figs 36–37 [non Hirtoscala pseudoscalaris ( Brocchi, 1814) ].

* [ Scalaria View in CoL ] Duboisiana d’Orb.—d’Orbigny 1852: 30, nr. 410 [nov. nom. pro Scalaria pseudoscalaris View in CoL of Dubois de Montpéreux, 1831].

Type material. Holotype, specimen from Shushkivtsi (= Szuszkowce) ( Ukraine) illustrated in Dubois de Montpéreux (1831: 43, pl. 2, figs 36–37). The collection is lost.

Discussion. The illustration of this dubious species is very schematic and shows a small specimen with a weakly cyrtoconoid spire and unusually low whorls with deeply impressed suture, moderately widely spaced, low, thin, nearly orthocline lamellae and smooth interspaces. The aperture is unusually large with a thin peristome. The description of Dubois de Montpéreux (1831) does not add any details. The illustration might depict a very poorly drawn Hirtoscala miofrondiculoides ( Sacco, 1891) . In that case, Scalaria duboisiana d’Orbigny, 1852 would have priority over Scalaria (Hirtoscala) miofrondiculoides ( Sacco, 1891) but provisionally, we prefer to keep both taxa separate. Hirtoscala pseudoscalaris ( Brocchi, 1814) , from the Neogene of Italy, with which Dubois de Montpéreux (1831) identified the Ukrainian shell, differs in its higher whorls and less numerous lamellae (see lectotype in Pinna & Spezia 1978: pl. 53, fig. 3).

Paleoenvironment. Probably shallow marine, inner neritic.

Distribution in Central Paratethys. Badenian (Middle Miocene): Polish-Ukrainian Fore-Carpathian Basin: Shushkivtsi (= Szuszkowce) ( Ukraine) ( Dubois de Montpéreux, 1831).
