The new sp. is described and illustrated from a single cJ (Nova Friburgo, Hotel Fazenda Sao Joao, Pico do Monro Sao Joao, Rio de Janeiro, alt, 1820 m, 10-III-1990), deposited in Museu Nacional, Rio de Janeiro. It fits well in the subfamily and is separated from other Brazilian genera by: sectors of arculus separated at origin in all wings, superior appendages diverging distally, and synthorax with metallic blue reflections. A key to Brazilian Corduliinae is presented.
