The wasp genus Calliscelio Ashmead is presumed to be a diverse group of parasitoids of the eggs of crickets (Orthoptera: Gryllidae). A least one species has been found to be an important factor in depressing cricket pest populations. Here, the New World species of Calliscelio are revised. Forty-two species are recognized, 3 are redescribed and 38 are described as new. Four species are treated as junior synonyms of Calliscelio rubriclavus (Ashmead).
