This is a well-marked species, its grey head and purple abdomen 

 making it very conspicuous among the other species of the genus.

 body, neck, and occiput bronzy green. Abdomen almost entirely 

 covered by a spot of deep reddish purple. Crissum and under tail-

Examples from Batanta are of larger size, but otherwise do not

 localities. The species has a rather wide distribution among the 

 Papuan Islands.
