Abstract
A new genus and species Termihabena lirata gen. et sp. nov. is described from the Lower Permian reef limestones of Shakh-Tau (southern Cisuralia). The new genus includes another five species: T. nikitowkensis (Yakowlew, 1899), T. asiatica (Licharew, 1967), T. millegranosa (Girty, 1934), T. pinegensis (Mazaev, 2006), and T. sp. (Batten, 1985). T. pinegensis is re-described based on new, additional material. The morphological similarities and differences between the new genus and Deseretospira Gordon and Yochelson, 1987 are discussed. The diagnosis of the genus Deseretospira is emended and expanded. Deseretospira and Termihabena gen. nov. are assigned to the family Phymatopleuridae. Deseretospira includes D. venustiformis (Licharew, 1967), in addition to the type species. The revision showed that the two species Rhineoderma ferganica Licharew, 1967 and Yunnania semigranulosa Licharew, 1967 are synonymous with Deseretospira venustiformis (Licharew, 1967).
