Callambulyx sichangensis Chu & Wang, 1980

In the original description of Callambulyx tatarinovi [sic] sichangensis, Chu & Wang (1980) (STI 17229) used the specific epithet “sichangenata” in the heading to the descriptive text (p. 418) but “sichangensis” elsewhere in the work, in the legend to figure 1 (p. 418), in the legend to plate 1 (p. 424) and in the heading of the description in English (p. 425). This is a case of multiple original spellings and the correct name must be determined by the application of the Principle of the First Reviser. Shortly after publication, Chu & Wang (1980: 46) (STI 17228) referred to the taxon as Callambulyx tatarinovi sichangensis and so under Article 24.2.4 of the Code are deemed to have acted as First Revisers and fixed sichangensis as the correct name of the taxon. Under Article 19.3 of the Code, sichangenata is deemed to be an incorrect original spelling and not separately available. Subsequently, Inoue (1990: 1) (STI 18565) incorrectly treated ‡sichangenata as the correct name for the taxon when synonymizing it with Callambulyx poecilus poecilus. Eitschberger & Nguyen (2018) (STI 21890) claimed that “sichangenata” was the valid name based on “page priority” (“Seitenpriorität”) and that sichangensis was either an incorrect spelling or unjustified emendation “if we do what the rules of the ICZN require” (“wenn wir das tun, was die Regeln der ICZN vorschreiben”). However, as noted above, the correct application of the Code (Article 24.2.4) requires that the name sichangensis be accepted as the valid name for the taxon.
