 Kosmoclymenia xenostriata Korn & Price, 1987 from the late P. jugosus Zone at Dzikowiec in the Sudetes and Jabłonna in the Holy Cross Mountains. Diagnoza Oblique aperture of the conch with usually prominent growth lines and relatively breviconic appearance, umbonal wall rounded in profile. Porównanie The holotype is a juvenile specimen, but its oblique aperture profile is consistent with that of the Dzikowiec specimens at comparable stages of their ontogeny. In this respect they also resemble the lectotype of Kosmoclymenia wocklumeri (Wedekind, 1914) from the P. paradoxa Zone at Ense in Kellerwald, proposed by Korn and Price , which differs, however, in an angular profile of the umbonal part of its umbo and in mature whorl lacking ventrolateral furrows despite the large conch size. There is much variation in the prominence and regularity in distribution of growth lines among the Dzikowiec specimens showing their sinuous appearance. In a few specimens with prominent growth lines, lateral sinuses are not developed. They are thus more derived than K. xenostriata in this respect, which may place them within the range of variability of K. wocklumeri. Autekologia Występowanie geograficzne Dzikowiec and Jabłonna.
