[1] The lectotype specimen, collected by J. Fourgère at Chatham Island, is held at the Natural History Museum, London.

Forewings with apex produced, termen prominently angulated on vein 3 (middle of second segment); reddish-lirown, varying to light reddish-ochreous, variably mixed with whitish and dark fuscous; costa darker, strigulated with whitish; a dark reddish-brown sub-triangular spot on costa at 2⁄3, anteriorly undefined, its apex touching a blackish transverse dot before fissure, posteriorly followed by more or less ochreous-whitish suffusion; subterminal line sharply dentate, ochreous-whitish, usually nearly obsolete, but in one specimen in which the terminal area is suffused with dark reddish-brown very conspicuous : cilia reddish-fuscous, barred with whitish, on termen with tips beyond a blackish median line whitish, on dorsum with numerous small projections of black scales and a larger black scale- tooth at 2⁄3.

Hindwings fuscous : cilia whitish-fuscous, with indistinct darker median line on termen; on dorsum with rather large undefined black scale-tooth scarcely beyond middle of third segment, and numerous black-tipped projecting scales between this and base.

[4]This species varies in intensity of colouration but can be distinguished from A. falcatalis as A. aeolodes is smaller and darker and the second segment of the forewing has a more prominent angle on the edge most distant from the body.

[4] A. aeolodes is very similar in appearance to A. repletalis, a species found on the North and South Islands.

[6] Also A. repletalis is a smaller moth with a more indistinct dark triangle shaped pattern on its forewings.
