Dolbina formosana Matsumura, 1927

Synonymized with Dolbina inexacta by Inoue, 1973, Bull. Fac. domest. Sci. Otsuma Wom. Univ. 9: 106. Reinstated as a species by Brechlin, 2009, Entomo-Satsphingia 2 (2): 21. Synonymized with Dolbina inexacta as a subspecies by Heppner, 2012, Lepid. Novae 5: 32. Reinstated as a species by Kitching and Rougerie et al., 2018, Biodivers. Data J. 6: e22236. Heppner (2012) asserted that “The subspecies concept is that they are merely geographic labels for disjunct populations of a single species and need no specific morphological differences to be established as such. Each population surely has some differences, but geographic isolation should be the only criterion in using subspecies names”. There is no scientific justification for such a subspecies definition and it is therefore rejected.
