Original description, Scott 1864
Pl. III: Scott, 1864.
We are indebted to the Banksia serrata for providing us with many examples of this species, for, like their predecessors, they are by no means rare. Although no diversity can be discerned in the formation of their habitations, or in the choice of any favoured locality (several species will inhabit the same tree) yet these caterpillars vary greatly in their colouring from the ones we have described; they have the head black. First segment yellowish, darker anteriorly and squamose; the remaining portion of the body deep neutral tint, each segment possessing four spots along the back, the two front ones yellowish, the two hind ones white; and a lateral row of yellow spots, all emitting setae.
The larva is in length about 1 2/3 inch.
The chrysalis (fig. 1) light reddish-brown, with the head black and spinose.
In expanse of wings the perfect insect is from 1 to 1 ½ inch, and was developed in November.
The Antennae ... male (fig. 2) with small tufts underneath, female setaceous.
The Labial palpi (fig. 3) recurving in front to about the top of the eyes; terminal joint thin and pointed, 2nd joint somewhat longer and more robust, basal small, about ¼ the length of the second.
The Legs ... anterior pair small; 2nd pairs (fig. 4) larger, with 3 apical spurs on tibiae; posterior pairs long, with 4 large spurs.
The entire surface of the insect is pearly-white, the anterior wings speckled with minute black dots, and along the costa a yellowish tinge; the posterior wings have a slight pinkish hue.
The moth and larva are depicted with a small limb of Banksia serrata.

Food plants: Larva boring in stem. Larval foodplant: Banksia serrata, B. integrifolia (Proteaceae). (Edwards, 2003).
Flight period: October, December
Distribution: New South Wales, Queensland. Endemic. (Edwards, 2003).

Remarks: The male genitalia suggest that this species is incorrectly placed in Cryptophasa, but may be more likely to be a part of the Illidgea-Phthonerodes group of genera.
