Subspecies
No subspecies.
Genus often merged with Hirundo, but DNA studies support retention of separate taxa. Affinities of present species unclear. Has been considered distinct from others of genus on account of differences in plumage coloration, bill shape, nesting habits (solitary), nest shape and eggs (usually unspotted), but these may be adaptations to forest environment.
