Sylvia (acrocephalus) agricola
near Nellore, Tamil Nadu, India.
Has been considered conspecific with one or both of A. tangorum and A. concinens; differs from each, however, in combination of plumage characters and biometrics; furthermore, DNA studies indicate c. 7.5% divergence from A. tangorum. Geographical variation appears very weak, as plumage differences heavily influenced by effects of wear. Race capistratus frequently merged with nominate, while initial discovery of substantial genetic difference (4.5%) between races septimus and nominate#R is now considered erroneous, as more detailed DNA analysis found no evidence of molecular structure between these two; the species is perhaps best treated as monotypic#R#R. Three subspecies recognized.
