Lectotype designation for Peleus aeacus Swainson, 1831

The name Peleus aeacus Swainson, 1831 (type locality at least in Suriname) was proposed from an unstated number of specimens that, in addition to the specimen shown on pl. 284, fig. F in Cramer (1780), included the specimen illustrated in Swainson (1831). It is not a replacement name, but a name that, according to Swainson, included Cramer’s concept of Papilio peleus Linnaeus, 1763 . Cramer’s specimen, although it was included in the type series, does not agree with the original description, because the forewing discal band is not “united to a spot” between the bands, and is not conspecific with the specimen illustrated by Swainson (1831). Therefore, Swainson’s specimen better represents the author’s concept of this species. To stabilize nomenclature and define the name P. aeacus objectively, N.V.G. hereby designates a syntype illustrated on pl. 75, fig. 2 in Swainson (1831) as the lectotype of Peleus aeacus Swainson, 1831 . The provenance of this specimen remains unknown, but this phenotype has been known from South America (most probably the Guianas region), which becomes the type locality of this taxon. This lectotype designation is necessary to exclude Cramer’s specimen as the name bearer.
