The sawfly genus Barilochia Malaise (Pergidae: Perreyiinae) was known from a single specimen of one species, B. brunneovirens Malaise, from San Carlos de Bariloche, Rio Negro, Argentina. A second species from Chile, B. longivalvula, n. sp., is described and illustrated. A male of Barilochia is described for the first time. The possible host plant is Nothofagus dombeyi (Coihue) (Nothofagaceae).
