Male with eye small (half as wide as distance between eyes) ( Fig. 79 View FIGURES 75–91 ); pygidium 3.5x longer than sternum VIII greatest length, with lateral margins slightly convergent posteriad, posterior margin with median third rounded, ventral keels absent ( Figs. 83–85 View FIGURES 75–91 ); arms of sternum IX lacking stout subapical setae, subparallel, apices rounded, right arm slightly longer ( Figs. 86–88 View FIGURES 75–91 ). Female with antenna moniliform, antennomere III slightly longer than pedicel ( Fig. 95 View FIGURES92–102 ); distance between antennal sockets shorter than apical maxillary palpomere width ( Fig. 96 View FIGURES92–102 ); pronotal greatest width greater than distance between posterior angles, wider than elytral humeral distance, anterior margin of pronotum rounded ( Fig. 81 View FIGURES 75–91 ); elytron moderately dehiscent ( Fig. 92 View FIGURES92–102 ), sternum VI with posterior margin straight ( Fig. 99 View FIGURES92–102 ), sternum and tergum VII connected by membrane; sternum VII as sclerotized as VIII ( Fig. 99 View FIGURES92–102 ), sternum VIII with posterior margin straight ( Fig. 101 View FIGURES92–102 ).

Description. Colour pattern ( Figs. 75–77 View FIGURES 75–91 , 92–94 View FIGURES92–102 ) overall dark brown, except by the translucent sternum VIII and outer margins of pygidium, and the yellow spots of rudimentary larval lanterns on sternum VIII.

Female. Antenna moniliform, antennomere III slightly longer than pedicel ( Fig. 95 View FIGURES92–102 ); distance between antennal sockets greater than apical maxillary palpomere width ( Fig. 96 View FIGURES92–102 ); pronotal greatest width greater than distance between posterior angles, wider than elytral humeral distance, anterior margin of pronotum rounded ( Fig. 98 View FIGURES92–102 ); elytron moderately dehiscent ( Fig. 92 View FIGURES92–102 ), sternum VI with posterior margin straight ( Fig. 99 View FIGURES92–102 ), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 99, 101 View FIGURES92–102 ); ovipositor with proximal plates separated, membranous, proximal plate as wide as long ( Fig. 102 View FIGURES92–102 ).

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.
