Megalurus albolimbatus The Fly River grassbird (Poodytes albolimbatus) is a species of Old World warbler in the family Locustellidae.

Its natural habitats are freshwater marshes and lakes.

The Fly River grassbird was formally described in 1879 by the Italian naturalists Luigi D'Albertis and Tommaso Salvadori from specimens collected near the Fly River in New Guinea.

They coined the binomial name Poodytes albolimbatus.

[2] The genus name combines the Ancient Greek poa meaning "grass" with dutēs meaning "diver".
