Description. Total length 13.6–16.7 mm. Body black, shining with antennomeres 4–11, palpi, tarsi and genital segment reddish brown.

Head. Ovally elongate ( Fig. 17 View FIGURES 11–19 ); 1.28x as long as wide; slightly convex dorsally and ventrally; dorsal surface with very dense umbilicate punctures, ventral surface with moderately dense umbilicate punctures separated by 2–3x their width ( Fig. 23 View FIGURES 20–24 ), unevenly distributed; temple flattened ( Fig. 28 View FIGURES 25–34 ); eyes 0.28x as long as head, interocular distance 0.65x cephalic width (at eye level); first antennomere 1.67x as long as antennomeres 2–3 combined, apical antennomere 0.92x as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54 View FIGURES 53–61 ); with mandibular external channel; apical maxillary palpomere conical ( Fig. 40 View FIGURES 35–46 ), 1.29x as long as preapical palpomere; apical labial palpomere asymmetrically conical ( Fig. 45 View FIGURES 35–46 ), longer than preapical palpomere.

Thorax. Pronotum 1.46x as long as wide; as wide as head; with dense fine punctures, except for wide longitudinal impunctate area ( Fig. 51 View FIGURES 47–52 ); with depressed area poorly visible at each side of posterior third. Elytra 1.05x as long as pronotum, with fine setae as dense as those on head and pronotum. Transverse prosternum, with fine setae as dense as those on meso and metasternum.

Abdomen. Densely covered with long, pale setae.

Aedeagus. Elongate; total length 1.85 mm; parameres 0.35x total length of median lobe; apical area of median lobe 0.32x total length of median lobe; internal sac with weakly sclerotized structures ( Fig. 83 View FIGURES 78–92 ).

Variation. The holotype is shorter than remaining specimens. Antennomeres 4–11 can be almost black to brown, the apical half of last antennomere can be red or yellow, the genital segment varies from reddish brown to black in the anterior half, to entirely reddish brown. Two specimens have reddish brown legs.

Comparison. This species is similar to R. longiceps in the ovally elongate head. Renda nitida and R. longiceps can be distinguished from R. mesoamericana , R. minor , R. lescheni and R. brasiliana by the ovally quadrate and shorter head. Renda nitida is separated from R. longiceps by the head slightly convex dorsally, the apical antennomere shorter than antennomeres 9–10 combined, the ventral surface of head with moderately dense umbilicate punctures and the elongate parameres of the aedeagus (0.35x the length of median lobe). Renda longiceps has the dorsal head clearly convex, the apical antennomere as long as antennomeres 9– 10 combined, the ventral surface of the head with very dense umbilicate punctures and short parameres of the aedeagus (0.24x the length of median lobe).

Etymology. The species name is derived from the Latin word “nitida” and refers to the shiny black color of this species.

Geographic distribution. Bolivia, Brazil, Ecuador and Peru.
