Genetic data#R suggest that this species, until very recently believed extinct but then rediscovered#R, is sister to C. typicus, which it resembles closely in structure; both were earlier thought to belong with the “C. enca complex”, but differ from it in behaviour and vocalizations. Monotypic.


Banggai Is (Peleng I; probably extinct on Banggai I#R), off E Sulawesi.
