The species inhabits a variety of habitats including native forest clearings, shrubland, coastal dunes and gardens.

[1] The male lectotype specimen, collected in Auckland, is held at the Natural History Museum, London.

Forewings acute, with many cinereous costal points, which are oblique outward towards the disk, and are more numerous than the cinereous streaks, which are oblique inward from the middle of the breadth to the interior border; two brown costal marks; first mark at one-third of the length; second at two-thirds of the length, larger than the first; a pale fawn-coloured costal patch between the second streak and a cinereous transverse zigzag submarginal line, which is partly bordered on the inner side by deep black; space between the submarginal line and the undulating black marginal line dark cinereous; fringe pale.

[7] This species is very similar in appearance to A. falcatalis but is a smaller moth with a more indistinct dark triangle shaped pattern on its forewings.

[7][5] A. repletalis can be found in a variety of habitats including in native forest clearings, shrubland, coastal dunes and gardens.
