Eight new synonyms for four species are proposed: Nemophora badagongshana Liao, Hirowatari & Huang in Liao, Hirowatari, Yagi, Wang, Wang & Huang, 2023, syn. nov. of Nemophora aurifera (Butler, 1881); Nemotois chrysocharis Caradja, 1938, syn. nov. of Nemophora sinicella (Walker, 1863); Nemotois diplophragma Meyrick, 1938, syn. nov. of Nemophora melichlorias (Meyrick, 1907); Nemophora basalistriata Liao, Hirowatari & Huang in Liao, Hirowatari, Yagi, Wang, Wang & Huang, 2023, syn. nov. of Nemophora melichlorias (Meyrick, 1907); Nemotois limenites Meyrick, 1914, syn. nov. of Nemophora aurifera (Butler, 1881); Nemophora quadrata Liao, Hirowatari & Huang in Liao, Hirowatari, Yagi, Wang, Wang & Huang, 2023, syn. nov. of Nemophora aurifera (Butler, 1881); Nemotois rubrofascia formosicola Matsumura, 1931, syn. nov. of Nemophora sakaii (Matsumura, 1931); Nemotois servata Meyrick in Caradja, 1925, syn. nov. of Nemophora aurifera (Butler, 1881).
