Locustellidae
Among the "warbler and babbler" superfamily Sylvioidea , the Locustellidae are closest to the Malagasy warblers , another newly recognized ( and hitherto unnamed ) family; the black-capped donacobius ( "Donacobius atricapillus" ) is an American relative derived from the same ancestral stock and not a wren as was long believed .
