Redescription of Japanagromyza inferna Spencer, first recorded from Brazil, and a key to the Neotropical species of Japanagromyza Sasakawa (Diptera, Agromyzidae)

Japanagromyza inferna Spencer is recorded for the first time from Brazil, in the North coast of the State of Rio de Janeiro, inducing galls in Centrosema virginianum L. (Fabaceae). The species is redescribed, with illustrations of male and female terminalia. A key to the identification of the Neotropical species of Japanagromyza Sasakawa is presented
