Abstract
A new species of Cosmetidae belonging to the genus Metavononoides Roewer, 1928 is herein described. Metavononoides melanacanthus sp. nov. is clearly recognized by its distinctive tarsal formula, its long legs (reaching over 60 mm), and by its characteristic color pattern. The new species is the twelfth species included in the genus. It is known only from two localities: the type locality, Barra de São João, Casimiro de Abreu and from Aldeia Velha, Rio de Janeiro, Brazil.
