The species was determined as Rectoclymenia aff. arietina (Sandberger, 1853) but the conch shape points rather to Cteroclymenia rozmanae Bogoslovsky, 1979 as its closest relative. The Polish species is less involute, which suggests its underived status. Unfortunately, the available evidence on suture and growth lines is insufficient to determine more precisely its relationships and to define new species. Autekologia Występowanie geograficzne
