Mount Goliath, Border Range, New Guinea.
When Pachycephala tenebrosa (which see) was placed in present genus, it had priority, so present species was listed as C. umbrina; with removal of former to Pachycephala, present species’ senior name of tenebrosa is reinstated. Variation in plumage considerable, and supposedly darker race atra may be no more than an extreme individual, darkness possibly increasing with age; sometimes treated as monotypic#R. Two subspecies tentatively recognized.
