Traditionally thought to form a species-group with N. nipalensis, N. bartelsi, N. alboniger (with N. nanus) and N. philippensis (with N. pinskeri). Recent genetic data, however, suggested that present species and N. philippensis (with N. pinskeri) are closer to N. cirrhatus#R. Monotypic.

Distribution:

Sulawesi and offshore islands of Muna and Butung; Banggai Is (Peleng, Labobo) and Sula Is.
