Female. Antenna moniliform, antennomere III slightly longer than pedicel ( Fig. 95 ); distance between antennal sockets greater than apical maxillary palpomere width ( Fig. 96 ); pronotal greatest width greater than distance between posterior angles, wider than elytral humeral distance, anterior margin of pronotum rounded ( Fig. 98 ); elytron moderately dehiscent ( Fig. 92 ), sternum VI with posterior margin straight ( Fig. 99 ), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 99, 101 ); ovipositor with proximal plates separated, membranous, proximal plate as wide as long ( Fig. 102 ). Etymology. The specific epithet carioca , a name in apposition, is the gentilic name for people from the city of Rio the Janeiro, where this new species was collected. Type Material.
