Abstract

Two species of Tachygonidius are described from the Atlantic coast of Brazil: T. fluminensis sp. nov. (type locality: Restinga da Marambaia, Rio de Janeiro) and T. paulensis sp. nov. (type locality: Boa Esperança do Sul, São Paulo). The former species develops as a leaf miner in a species of Ochnaceae. Sexual dimorphism related to the form of the declivous portion of pygidium, deeper in male and less deep in female, is reported for the first time in T. fluminensis. A key for the four known species of Tachygonidius is provided.
