Measuring about 16 centimetres (6.3 in) in length, it is brown overall, though striped with black and with grayish underparts. Its tail is long.
The Zapata wren is confined and endemic to the Zapata Peninsula of southern Cuba. It was formally described by American herpetologist Thomas Barbour, who gave it the specific name cevererai in honour of the wren’s discoverer, Fermín Zanón Cervera, a Spaniard who had stayed on after the Spanish–American War and become a professional naturalist.
Barbour had been accompanied by Cervera on his previous visits to Cuba, and on hearing of the strange birds to be found in the Zapata area, he sent the Spaniard on a series of trips into the region, eventually leading to the finding of the wren.
The Zapata wren's habitat is typically freshwater marsh and lowland savanna with scattered bushes and low trees. It feeds on insects, spiders, small snails, lizards and berries. The wren typically makes its nest in sawgrass tussocks. It is thought to breed between January and July.
