The adult moths of this species have pale brown wings, each having several dark wavy submarginal arcs of dark spots. The males have feathery antennae, and the females have thread-like antennae. The wingspan is about 3 cms.

The species has been found in Australia in

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

    The genus Tephrosia has diagnostic characters that differ from those in this species, so this species needs to be placed with the species currently named Boarmia phricomita in another new genus, but no suitable genus has yet been formally described.
