Material.—Five complete Pa elements from Mytkiv Formation. Section and sample 45/ 170 m.

Remarks.—Podolian specimens do not differ significantly from the type material from Spain: the elements have thick, elongated (0.9–1.1 mm) and high (about 0.2–0.35 mm) blade. Lower margin of both sections of the blade nearly straight. Basal cavity with terraced, rounded and asymmetrical lips, located approximately at mid−length or closer to the posterior end of the blade. Cusp is considerably bigger, the anterior denticles and anterior end of the blade somewath higher.

Stratigraphic and geographic range.— Caudicriodus transiens Zone in Podolia, Lanea omoalpha and Ancyrodelloides trigonicus zones in Spain, middle Lochkovian in central Nevada Spanish Pyrenees and Czech Republic.
