Previously Caprimulgus parvulus heterurus.It is elevated to full species status and is the sister species of Hydropsalis parvulus(formerly C. p. parvulus). Diagnosis Small, brownish-grey, with broad buff neck collar and a white throat patch. White tips on outermost primaries and tail feathers. Very similar to H. parvulus, but more extensive white markings near the tips of the feathers. There is 5% divergence in ND2sequences between H. heterurusand H. parvulus. Comments Genetic evidence in this study supports splitting H. parvulusinto two phylogenetic species along subspecies lines ( Fig. 7). This is congruent with the taxonomic modifications of Cleere (2010), based on observations on the morphology and vocalizations of the two taxa. Both species are placed in the genus Hydropsalis, as discussed earlier.
