Probably a species complex rather than a single species. N forms living in montane habitats (newarensis, ticehursti, caligata, laotiana) larger, with different vocalizations, likely to represent a separate, polytypic species; race bartelsi likewise vocally and morphologically distinct and living at higher elevations, probably also specifically distinct, as is the small, little-known niasensis (these treated as separate species but without full review of evidence in recent monograph#R); detailed analysis needed. In addition, Sri Lankan ochrogenys sometimes considered synonymous with indranee; chaseni possibly synonymous with nominate, but sometimes included in myrtha#R; myrtha and nyctiphasma perhaps doubtfully distinct from maingayi. Further races described are connectens (single specimen from C India), included in indranee; rileyi (S Thailand) in maingayi; and orientalis and shahensis, both treated as synonyms of ticehursti. Fourteen subspecies recognized.
