(Figs 75–102)
Diagnosis. Elytron entirely dark-brown (Figs. 75, 92). Male with eye small (half as wide as distance between eyes) (Fig. 79); 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); arms of sternum IX lacking stout subapical setae, subparallel, apices rounded, right arm slightly longer (Figs. 86–88). Female with antenna moniliform, antennomere III slightly longer than pedicel (Fig. 95); distance between antennal sockets shorter 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. 81); elytron moderately dehiscent (Fig. 92), sternum VI with posterior margin straight (Fig. 99), sternum and tergum VII connected by membrane; sternum VII as sclerotized as VIII (Fig. 99), sternum VIII with posterior margin straight (Fig. 101).
Description. Colour pattern (Figs. 75–77, 92–94) 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. Hypomeron ventrally acute (Fig. 80, 97).
Male. Eye small (half as wide as distance between eyes) (Fig. 79), shorter than head (Fig. 80); antennomere IV 2x longer than wide (Fig. 78); pronotum with lateral margins narrower than distance between elytral humeri, posterior angles obtuse (Fig. 81); 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); sternum VIII strongly emarginated (Fig. 85); sternum IX 3x longer than aedeagus, arms lacking stout subapical setae, subparallel, apices rounded, right arm slightly longer (Figs. 86–88); syntergite bearing a distinct transversal suture, lacking medial suture (Fig. 86); phallus with lateral margins biconcave, basal projections of parameres fused, then projected basally, paramere strongly curved inwards, apex rounded (Figs. 89, 91).
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.
