Abstract
The unique large-sized solitary Rugosa of the upper Khivachian Stage in the Omolon terrane are a Late Permian psychrosphaeric fauna, originally situated in the North of Pangea in northeastern marginal basins of Angarida (boreal realm at latitude of 70°N). Faunistic relations are only indicated by the predominating species Sochkineophyllum zavodovskyi Sokolov, 1959, which is redescribed and removed to the recently introduced monotypic neighbouring genus Fedorowskites Chwieduk, 2013 from the Svalbard Archipelago (north of Lopingian Pangea at 45-50°N). Its type species Fedorowskites spitsbergensis Chwieduk, 2013 (Wordian–Capitanian) and Sochkineophyllum turgidiseptatum (Tidten, 1972) (Roadian–Capitanian) are illustrated by new Svalbard collections. Fedorowskites survived at the late-Captanian global Kamura-Event. The poor present knowledge about further northern Lopingian corals includes only Greenland and the European Zechstein-Basin, but there is no one species in common with the Omolon Massif. A new morphological term lacunula interseptalis is proposed for nearly forgotten skeletal elements, already described by Ludwig (1865) and Kunth (1869).
