Description. Total length 14.5–16.2 mm. Body black, with antennomeres 4–11, labrum, palpi, tarsi and genital segment red.
Head. Oval, slightly widened posteriorly (similar to Fig. 13 View FIGURES 11–19 ); 1.26x as long as wide; dorsally and ventrally convex; dorsal surface with very dense, umbilicate punctures, ventral surface with dense, umbilicate punctures separated by less than twice their width ( Fig. 24 View FIGURES 20–24 ); temple with superior and inferior temporal carinae and a concave area ( Fig. 34 View FIGURES 25–34 ); eyes 0.3x as long as head, interocular distance 0.62x cephalic width; first antennomere 1.83x as long as antennomeres 2–3 combined, apical antennomere 0.93x as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54 View FIGURES 53–61 ); with mandibular external channel; apical maxillary palpomere elongate ( Fig. 38 View FIGURES 35–46 ), 2.15x as long as preapical palpomere; apical labial palpomere slightly widened at apex ( Fig. 44 View FIGURES 35–46 ), almost twice as long as preapical palpomere.
Thorax. Pronotum 1.5x as long as wide; 1.03x cephalic width; with dense, fine punctures, except for wide longitudinal impunctate area ( Fig. 52 View FIGURES 47–52 ); with poorly developed depressed area at each side of posterior third. Elytra as long as pronotum; with fine setae as dense as those on head and pronotum. Anterior half of prosternum with a poorly developed longitudinal carina; with fine setae as dense as those on meso and metasternum.
Abdomen. Covered with setae as dense as those on remaining body.
Aedeagus. Ovally elongate; total length 1.72 mm; parameres 0.42x as long as median lobe; apical area of median lobe 0.23x total length of median lobe; internal sac with weakly sclerotized structures ( Fig. 86 View FIGURES 78–92 ).
Variation. Coloration in specimens can vary as follows: legs (except tarsi) almost black to reddish brown; antennomeres 1–3 black to reddish brown; apex of last antennomere red or yellow. The umbilicate punctures on the ventral surface of the head vary from dense to very dense. The carinate line on the prosternum can be slightly to moderately developed. Female specimens studied have wider pronotal punctures than males.
Comparison. This species is similar to R. brendelli , R. clavicornis and R. pronotalis in the finely punctuated pronotum, mainly black body and the elongate apical maxillary palpomere. Renda cariniventris is distinguished from R. brendelli by the superior and inferior temporal carinae that delimit the concave area. It can be distinguished from R. pronotalis by the oval shape of the head and the carinate prosternum ( R. pronotalis has an ovally quadrate head and no carinate line on the prosternum). It can be separated from R. clavicornis by the slightly, posteriorly narrowed head with clearly convex dorsal and ventral surfaces, apical antennomere shorter than antennomeres 9 and 10 combined and by the shorter aedeagus with long parameres and internal sac with weakly sclerotized structures.
Etymology. The species name is derived from the Latin words “carinae” and “ventris” and refers to the longitudinal, fine carina on the anterior half of the prosternum.
Geographic distribution. Brazil and French Guiana.
