1985 Salopina crassiformis ( Kozłowski, 1929) ; Nikiforova et al. 1985: 12–14, pl. 1: 4.

Material.—7 shells, 53 ventral and 42 dorsal valves. The species occurs scarcely at 0.7 m (bed −1) above the S–D boundary but becomes much more common at 5.5 m (beds 47–48) above the boundary.

Remarks.—Describing the external variability of the species, Kozłowski (1929: 68) reported only 8 shells from 5 localities. During the present investigation 7 additional shells have

been recovered from the trench at Dnistrove. Nikiforova et al. (1985) selected a neotype from the Khudykivtsi Beds at Tselyuev−Myshakovtsy. Thus, this is a rather rare, small−sized (rarely exceeds 7 mm in length) species in Podolia.

The present specimens fully agree externally with those described by Kozłowski (1929) from the Borshchiv Horizon as Dalmanella crassiformis . More recently Nikiforova et al. (1985) assigned the species to Salopina Boucot, 1960 , but eventually it was attributed by Johnson (1990) to his new genus Talentella Johnson, 1990 . According to Kozłowski (1929) the species also occurs in the Malinovtsy and Skala horizons (Silurian) but Nikiforova et al. (1985) noted that it can be identified with certainty only from the Khudykivtsi Beds of the Borshchiv Horizon.

Stratigraphic and geographic range.— The species has been found in several localities in Podolia, all representing Khudykivtsi Beds of the Borshchiv Horizon. Walmsley et al. (1969: 509) reported the species from the lower Devonian of Nevada and northern Yukon Territory.
