Food plants:
Flight period: October, November. December.
Distribution: New South Wales, Queensland. Endemic. (Edwards, 2003).

Remarks: The male genitalia, with their narrow, pointed uncus and broad, spathulate gnathos, are uncharcteristic of Cryptophasa. The valvae lack a sinus beneath the claspers. Despite the pectinated antennae, this species is closer in many respects to Xylorycta.
