 It differed from the typical "P. v. varius" in having a broad chestnut-coloured band on the upper mantle, olive-green (not dark grey) lower mantle, and orangey (not white) sides to the head (Harrap & Quinn 1996, del Hoyo et al.2007).Like many bird taxa from the Okinawa region, the scientific name is named after the veteran specimen collector Hyojiri Orii.
