Subspecies
Has in the past been placed in monospecific Dissemurulus, or in Dissemuroides. May form a superspecies with Greater Racquet-tailed Drongo (Dicrurus paradiseus) and often treated as conspecific, but differs in tail morphology and probably in voice. Molecular-genetic studies required in order to elucidate taxonomic status. Few intergrades with subspecies ceylonicus of Greater Racquet-tailed Drongo (Dicrurus paradiseus) formerly reported along border between wet and dry zones, but interbreeding not now possible, since suitable habitat no longer remains between the two ecological zones, now completely separated.
