Abstract
The genus Rotalites was established by Leleshus (1970: 97) for fossil Upper Silurian heliolitoids (Anthozoa) from Southern Tien Shan. However, the name is preoccupied by Rotalites Lamarck (1801: 401) of Foraminifera (Protista) (cf. Loeblich & Tappan, 1987). In accordance with the International Code of Zoological Nomenclature, Chekhovichia nom. nov. is proposed here as a replacement name for Rotalites Leleshus non Lamarck.
