Aegotheles affinis


, 1876,

Arfak Mountains, New Guinea


Until recently considered conspecific with A. bennettii, but considerable genetic distance coupled with morphological differences (notably in size) and the geographical position of the two subspecies of affinis suggest that treatment as a separate species is warranted#R; this argument accepted here pending more detailed morphological comparisons and the establishment of vocal evidence. It has also been suggested that race terborghi could, in fact, represent a third species#R. Two subspecies recognized.

Subspecies and Distribution
  • A. a. affinis Salvadori, 1876 – Arfak Mts, in Vogelkop Peninsula (NW New Guinea).
