Trichophorus calurus

Has often been regarded as conspecific with C. ndussumensis owing to similarity in appearance, but the two differ both vocally and morphologically. Published reports of hybridization between latter and race emini of present species in NE DRCongo seem to be based on observation of individuals apparently showing combination of characters then thought to be restricted to each form. Three subspecies recognized.
