Dinelli's Doradito

Dinelli's doradito is about 11 cm (4.3 in) long. The sexes have essentially the same plumage though females are duller than males. Adults have a mostly yellowish olive head whose crown, lores, and cheeks have a rufescent tinge. Their upperparts are yellowish olive. Their wings are a grayer olive, with thin buff edges on the flight feathers and wing coverts; the last show as two faint wing bars. Their tail is a brower olive. Males' throat and underparts are bright yellow; females' are duller yellow. Both sexes have a dark brown iris, a slender, black, warbler-like bill, and blackish gray legs and feet.

Dinelli's doradito is found from north-central Argentina's Córdoba north into western Paraguay and slightly into southern Bolivia. The South American Classification Committee of the American Ornithological Society has unconfirmed sight records in southern Brazil and therefore lists the species as hypothetical in that country. The species inhabits beds of reeds, grassy marshes, and shrublands near water. In elevation it reaches only 500 m (1,600 ft) above sea level.

The diet of Dinelli's doradito has not been detailed but is known to include insects and spiders. It forages in dense marsh vegetation.
