Remarks

The name xuthus was placed on the Official List of Specific Names in Zoology (ICZN, 1954: Opinion 286) and xanthus (1767: 751) was placed on the Index of Rejected and Invalid Specific Names in Zoology. "Remarks. This species was originally described by Linnaeus as xanthus, an incorrect original spelling, corrected to xuthus by Linnaeus in the Corrigenda. Corbet (1949) identified xuthus as the species previously described by Linnaeus as ajax, a name that could have applied to three different species. The type locality was cited by Corbet (1949: 198) as Canton and the collector as "[P. Osbeck]", but the species is not mentioned by Osbeck (1765) as having been collected or purchased by him. It is very likely that the Clerck figure cited by Corbet (1949: 194) for agamemnon is actually an unfinished illustration of this species. Corbet submitted an application to the Commission to suppress the name ajax. By their action, the Commission established the identity of xuthus as the species represented by the Linnaean type specimen of ajax. We have formally designated this specimen (Fig. 20) as lectotype. The name xuthus was placed on the Official List of Specific Names in Zoology (ICZN, 1954: Opinion 286) and xanthus (1767: 751) was placed on the Index of Rejected and Invalid Specific Names in Zoology. The nominate subspecies of this polytypic species is widespread in China (see Chou, 1994: 157) so Canton, being a well known Linnaean locality, is likely to be the type locality."
