Tewomorpha, a new name for Tewoella Ding and Li, 1987 (Bivalvia: Heteroconchia: Modiomorphidae: Butovicellinae), preoccupied by Tewoella Sun, 1979 (Protista: Fusulinoidea: Palaeofusulininae)
In 1987, a new genus nameTewoella Ding and Li, 1987 was proposed for some Lower Devonian marine bivalves from Tewo, Gansu Province, northwestern China. However, as early as 1979, Sun Xiu-fang had established the identical genus name Tewoella Sun, 1979 (type species: Tewoella longa Sun, 1979) for the fusulinoidean fossils from the Late Permian Shi-guan Group also in Tewo, Gansu Province, northwestern China. According to Article 60.3 of ICZN, a new genus name, Tewomorpha nom. nov. is here proposed to replace Tewoella Ding and Li, 1987 based on the same type species, Tewoella xiawunaensis Ding and Li, 1987.
