The status of Selagis corusca as a distinct species (in SA at least) is uncertain. The 155 specimens previously assigned that name on these webpages were provisionally transferred in December 2025 to S. chlorianatha, a species hitherto recognised in SA by just a few females.

All the SA specimens previously treated as S. corusca appear to be males and were recorded as having been attracted to blue lures, apart from one old collection by Tepper from Adelaide. They range from forms with mostly dark blackish grey to bronze colouration to forms brightly copper-coloured all over. In between are many coppery forms with varying extents of blackish areas, and predominantly copper forms with green iridescence or areas of definite green colouration. The latter provide the best match with the type description of Waterhouse 1882. However, all these male forms have been found together in sites where female S. chloriantha occur and appear to be a single variable interbreeding population. Male specimens from WA exhibit similar variation from dark to coppery-coloured forms.

In his revision of the genus (known then as Curis) Carter 1928 separated Selagis corusca in his key by the elytra being unicolourous and coppery. He referred to a mutilated example in the SA Museum from Adelaide. The early Adelaide collection by Tepper has light coppery elytra consistent with his account.

The original description by Waterhouse 1882 makes no mention of copper colouration and only refers to colour on the pronotum 'tinted with golden green on the disk' and with short deep blue elongated spots on either side of the midline. Waterhouse's final comment that it formed a link between S. caloptera and S. viridicyanea suggests that his material may have had elytra with substantial green colouration. He merely designates the source of material as Australia.

Eyre Peninsula male specimens are generally consistent in size and body shape; many are brightly and predominantly copper-coloured throughout, while others grade towards blackish-purple tones particularly on the elytra, and a few exhibit greenish tones. Carter 1928, p.275 commented on the bewildering colour variation in some species of the genus. Examination of images of the possible type specimens of S. corusca also indicates much colour variation in this species. At this stage a single interbreeding population makes the most sense, with S. corusca as applied in SA being treated as synonymous with, or a misapplication for, the earlier name, S. chloriantha.
