Barlow's Lark is lumped with Dune Lark following Donald and Alström (in preparation), who show that barlowi is essentially indistinguishable from nominate erythrochlamys, and that the taxa patae and cavei are better treated as subspecies (or perhaps even color morphs of erythrochlamys). Genetic divergence, at least as measured by mitochondrial DNA, between Barlow's and Dune larks is very shallow (Alström et al. 2013), and their songs appear to be indistinguishable.
