Material.— Above 20 Pa elements from Khudykivtsi and Mytkiv Formations. Sections and samples: 14/5v, 6, 7, 14 V/5 , 105 /1, 16/1b, 1v, 2, 3, 4, 37/1, 1a, 1b, 2, 37A/2, 37B/1, 12/1a,18/1, 18A/5, 14/ 1,3 m, 45/ 170 m. Other elements of the multielement apparatus are still unknown .

Remarks.—Pa elements have intermediate shape between Ozarkodina typica Branson and Mehl, 1933 and Zieglerodina remscheidensis ( Ziegler, 1960) (for comparisons of this species see also Chatterton and Perry 1977: 791). Comparatively long (0.8–1.1 mm) blade twisted up in the anterior part and down in the posterior. The denticles are low, with wide basis; the one above the basal cavity slightly bigger. Also 3–4 anterior denticles higher than others, slightly bowed backwardly or (rarely) increasing rapidly and erect. Basal cavity located closer to the posterior end or approximately at mid−length.

Pandorinellina? formosa differs from the related to it Zieglerodina remscheidensis ( Ziegler, 1960) by sigmoidaly curved blade. It differs from somewhat similar Pandorinellina camelfordensis (Farrell, 2004) by wider and deeper basal cavity, as well as by bigger and rounded cavity lips.

Stratigraphic and geographic range.— Caudicriodus hesperius and Caudicriodus transiens zones, lower to middle Lochkovian in Podolia.
