    The species is found the southern half of Australia in

  • New South Wales,
  • Victoria, and
  • Tasmania.

    The moth is related to Azelina biplaga but is smaller, with smaller circles on the forewings, and the males have larger fringes than those of Azelina biplaga. The genera Azelina, Gynopteryx and Metrocampa are inappropriate for these species, but a suitable genus has yet to be found.
