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

Description. Colour pattern ( Figs. 75–77View FIGURES 75–91, 92–94View 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. 95View FIGURES92–102); distance between antennal sockets greater than apical maxillary palpomere width ( Fig. 96View FIGURES92–102); pronotal greatest width greater than distance between posterior angles, wider than elytral humeral distance, anterior margin of pronotum rounded ( Fig. 98View FIGURES92–102); elytron moderately dehiscent ( Fig. 92View FIGURES92–102), sternum VI with posterior margin straight ( Fig. 99View FIGURES92–102), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 99, 101View FIGURES92–102); ovipositor with proximal plates separated, membranous, proximal plate as wide as long ( Fig. 102View 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.
