Formerly treated as a race of Z. dauma, but differs in tail-tip pattern; wide geographical separation, with intervening related species (Z. heinei, Z. machiki), tends to support species status, but detailed evaluation of evidence needed, and present treatment provisional. Has been though to include Z. heinei as a small race, but the two shown to be sympatric without interbreeding, and songs somewhat different. Isolated race cuneata structurally rather distinct, and speculated as representing a different species. Described race macrorhyncha (from Tasmania) synonymized with nominate. Three subspecies recognized.

Subspecies and Distribution
  • Z. l. cuneata (De Vis, 1889) – #RNE Australia (NE Queensland).
  • Z. l. lunulata (Latham, 1801) – SE Australia, Tasmania, and islands in Bass Strait (King I, Flinders I).
  • Z. l. halmaturina (A. G. Campbell, 1906) – SE South Australia in Mt Lofty Range, Telowie Gorge Conservation Park and Wittaburra Forest, and on Kangaroo I.
