Napa, Okinawa, Ryukyu Islands.
In the past, sometimes placed in genus Sphenurus. Closely allied to T. sphenurus and T. sieboldii, and more distantly to T. oxyurus species-group. Hitherto considered conspecific with T. formosae, but recently recognized as a full species (and erroneously listed under the name riukiuensis)#R; split reaffirmed here on account of undifferentiated (continuous) green vs dull orange crown of male (3), dull reddish-brown vs bold reddish-purple carpal patch of male (2), and longer tail (effect size 4.01) (2). Two subspecies recognized.
