Austrocidaria stricta is a species of moth of the family Geometridae.

This species was first described by Alfred Philpott in 1915 using specimens collected on Bold Peak in the Humboldt Range by George Howes in February and named Xanthorhoe stricta.

[3] George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand.

Forewings triangular, costa almost straight, rather strongly arched apically, termen subsinuate, oblique; pale greyish-ochreous; markings fuscous-brown; numerous thin waved more or less parallel transverse lines, forming more distinct bands near base, before middle, at f and J; an obscure discal dot; outer margin of third band sinuate inwards above and below middle; an inwardly oblique thin subapical streak; a terminal series of black dots, connected by a very faint waved line.

[5][1] Other than the type locality of Bold Peak, this species has been observed in the Hunter Mountains in Fiordland, at an elevation of 3000 ft.[4] It has also been observed in the Dansey ecological district in Otago.
