One specimen, type, in February. (Lower, 1917).

Food plants:
Flight period: February.
Distribution: New South Wales. Endemic. (Edwards, 2003).

Remarks: This moth appears to me more likely to belong with Cryptophasa spp. of the assemblage surrounding Cryptophasa delocentra. If that is the case, the species is likely to be sexually dimorphic and males could be quite different in appearance (see C. delocentra).
