在Treatise双壳纲卷修订版的编撰过程中, Joseph Carter教授发现丁保良、李金华为甘肃迭部下泥盆统海相双壳类建立的属名Tewoella Ding and Li, 1987已被蜓类化石属名Tewoella Sun, 1979占用, 来函要求为之另立新名。经本人核实, 孙秀芳(1979, p. 165)为甘肃迭部上二叠统石关群的蜓类化石所创建的属名迭部蜓(Tewoella Sun, 1979; 模式种: Tewoella longa Sun, 1979), 完全符合“国际动物命名法规”有关属级分类群命名的各项要求, 故在此提出一个新的属名Tewomorpha nom. nov., 用以替代Tewoella Sun, 1979的次同义名Tewoella Ding and Li, 1987, 仍使用丁保良、李金华(1987)指定的模式种, 中文译名则无须更改。

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.
