A new rugosochonetid genus, Tethyochonetes gen. nov., is proposed for several species from the Lopingian (Late Permian) of China previously assigned to Waagenites Paeckelmann, 1930. Five species of Tethyochonetes are described, including two new species, Tethyochonetes? liaoi sp. nov. and Tethyochonetes chaoi sp. nov., and three revised species, Tethyochonetes quadrata (Zhan), Tethyochonetes longtanensis (Liao) and Tethyochonetes wongiania (Chao).
