The drongos, subfamily Dicrurinae, are a subfamily of small passerine birds of the Old World tropics in the family Dicruridae. Originally the family included the single genus Dicrurus (subfamily Dicrurinae), but now it has been expanded to include the subfamilies Rhipidurinae (Australasian fantails), Monarchinae ( monarchs and paradise flycatchers) and Grallininae (magpie-larks). The subfamily Dicrurinae contains two genera, the monotypic Chaetorhynchus, and Dicrurus, which contains about 25 species. The placement of the pygmy drongo (Chaetorhynchus papuensis) in the subfamily is in dispute on morphological and genetic grounds.
