Subspecies
No subspecies.
Acrocephalus agricola (Sibley and Monroe 1990, 1993) has been split into Paddyfield Warbler (Acrocephalus agricola) and Manchurian (Reed) Warbler (Acrocephalus tangorum) contra Alstrom et al. (1991) but following Helbig and Seibold (1999).
Forms a superspecies with Paddyfield Warbler (Acrocephalus agricola) and Blunt-winged Warbler (Acrocephalus concinens). Formerly considered a subspecies of Paddyfield Warbler (Acrocephalus agricola) or of Black-browed Reed-Warbler (Acrocephalus bistrigiceps), but recent morphological and DNA studies indicate that it warrants separate species rank.
Similar Species

Generally duller and more olive-brown upperparts.
