Other common names: Tuamotu Warbler

Conopoderas atypha


, 1919,

Fakarava, Tuamotu Archipelago


Has sometimes been considered conspecific with A. caffer and A. mendanae, but the three show obvious morphological, behavioural and genetic differences. Recent study of morphology and DNA has recommended that races flavidus and ravus (both of which occur on low-lying atolls) be subsumed within nominate#R. Six subspecies recognized.

Subspecies and Distribution
  • A. a. atyphus (Wetmore, 1919) – islands in NW Tuamotu Archipelago.
  • A. a. eremus (Wetmore, 1919) – Makatea I (NW Tuamotu).
  • A. a. niauensis (Murphy & Mathews, 1929) – Niau I (NW Tuamotu).
  • A. a. flavidus (Murphy & Mathews, 1929) – Napuka I (N Tuamotu).
  • A. a. palmarum (Murphy & Mathews, 1929) – Anaa I (WC Tuamotu).
