Comments. Similar to Janeirona vianai , differing from it by the maximum head width across the mandibular plates subequal to half the head width across the eyes, labium attaining the urosternite III, and metasternum flat. Differs from all species in the genus by the posterior margins of the eyes forming an angle of 45º with the longitudinal body axis.

Distribution: Brazil (Minas Gerais, Rio de Janeiro, São Paulo, and Santa Catarina).
