Original description, Meyrick 1890
Crypt. hierastis, n. sp.
Female 22-23mm. Head, palpi, antennae, thorax, and abdomen white; posterior extremity of thorax greyish. Legs dark fuscous, posterior tibiae white. Forewings elongate, costa gently arched, apex rounded, hindmargin obliquely rounded; 2 from near angle; glossy snow-white; a narrow dark fuscous streak along costa from before middle to apex, finely attenuated anteriorly; a moderate dark fuscous streak along inner margin from near base to anal angle: cilia white, at apex and towards anal angle fuscous-grey. Hindwings with veins 6 and 7 from a point; light fuscous, hindmarginal edge darker; cilia white.
York, West Australia; three specimens bred in December. The larva feeds on Hakea (an unidentified species with leaves metamorphosed into stout spines), making long contorted tubes of silk covered with refuse amongst the twigs, in October.

[Cryptophasa stochastis] Larva feeds on Hakea (the same species as C. hierastis [Potniarcha hierastis]), living in a barricaded tunnel and carrying in the spines for food, in October. (Meyrick, 1890).
