Traditionally thought to form a species-group with N. nipalensis, N. bartelsi, N. alboniger (with N. nanus) and N. lanceolatus. Recent genetic data, however, suggested that present species and N. lanceolatus are closer to N. cirrhatus#R. Until recently, N Philippine populations considered inseparable from C & S ones, but recently described form pinskeri (see below) now recognized as full species. Monotypic.
N Philippine Is (Luzon; probably this species on Mindoro).
