Genus Actinophrentis Ivanovski, 1967 .

Type species: Actinophrentis donetziana Fomichev, 1953 .

Diagnosis: Non-dissepimented, small, solitary corals with pinnately arranged major septa up to calice floor, united axially by stereocolumn; cardinal septum shortened from early maturity; counter septum distinctly or moderately permanently elongated; cardinal fossula reaches or almost reaches corallite axis; minor septa underdeveloped (after Fedorowski, 1987a, p. 36).

Remarks: Weyer (1975) unambiguously synonymised Actinophrentis Ivanovski, 1967 with Rotiphyllum Hudson, 1942 . Hill (1981) accepted Actinophrentis , though she did not rule out synonymy with the later genus. Fedorowski (1987a) stated the validity of the genus, especially based on the development of cardinal and counter septum (see diagnosis). He also discussed questionable synonymies with other genera, which include?p.p. Stereolasma Fomichev, 1953 non Simpson, 1900 and 1962? Longiclava Easton, 1962 . Actinophrentis columnare Fedorowski, 1987 from the lower Wolfcampian of Texas is known in time-equivalent strata from the northern Timan ( Kossovaya, 1996); unfortunately, its presence in the Urals and the Russian Platform cannot be deduced from this publication. However, the type species of the genus, A. donetziana Fomichev, 1953 is from the Donets Basin, Ukraine. One specimen described by de Groot (1963) to belong to Zaphrentites paralleloides de Groot, 1963 from the Sierra Corisa Limestone (Westphalian D = upper Moscovian) of northern Palencia (Cantabrian Mountains, Spain) was included by Fedorowski (2004) as Actinophrentis sp. In addition, Rodríguez et al., (2022, Table 1 ) accepted the presence of the genus in the Asturian Substage (upper Moscovian) of the Cantabrian Mountains without further discussion.

Geographic and stratigraphic range: Upper Moscovian of the Donets Basin ( Fomichev, 1953; Ivanovski, 1967) and the Cantabrian Mountains (northern Palencia, Spain) ( Fedorowski, 2004); Upper Pennsylvanian (Kasimovian) of Egypt ( Kora and Mansour, 1991 and this paper); lowermost Permian (Asselian) of N Timan Ridge ( Kossovaya, 1986); lowermost Permian (lower part of Wolfcampian Series = Nealian Stage) of Glass Mountains, western Texas ( Fedorowski, 1987a).
