Redescription. Total length 15.7–17.5 mm. Black body, with mouthparts, antennae, legs and genital segment reddish-brown.

Head. Ovally elongate, with obtuse posterior corners ( Figs. 9 View FIGURES 7–10 , 18 View FIGURES 11–19 ); 1.38x as long as wide; dorsal and ventral surfaces faintly convex; dorsal surface with dense, umbilicate punctures, these punctures becoming sparser or absent on vertex and anterior border; ventral surface with sparse, umbilicate punctures separated by more than 3x their width ( Fig. 22 View FIGURES 20–24 ); temple with superior and inferior temporal carinae and a slightly concave area ( Fig. 34 View FIGURES 25–34 ); eyes long (0.33x as long as head) and wide (interocular distance 0.58x cephalic width) ( Figs. 9 View FIGURES 7–10 , 18 View FIGURES 11–19 ); first antennomere 1.67x as long as antennomeres 2–3 combined, apical antennomere 0.91x length of antennomeres 9–10 combined; labrum bilobed ( Fig. 54 View FIGURES 53–61 ); mandibles with external channel poorly developed; apical maxillary palpomere conically elongate ( Fig. 39 View FIGURES 35–46 ), 1.82x as long as preapical palpomere; apical labial palpomere slightly widened and flattened toward apex ( Fig. 44 View FIGURES 35–46 ), more than 1.75x as long as preapical palpomere.

Thorax. Pronotum 1.61x as long as wide; 1.05x as wide as head; with fine moderately dense punctures, except for wide, longitudinal impunctate area; without depressed areas at each side of posterior third ( Fig. 52 View FIGURES 47–52 ). Elytra as long as pronotum; elytral disc with punctures as dense as those on pronotum. Prosternum with setae as dense as those on meso and metasternum.

Abdomen. First three visible abdominal segments with pale, long setae distributed on lateral and posterior borders, central areas of these segments with short, brown setae; remainder of abdominal segments completely covered by dense, pale, long setae.

Aedeagus. Ovally elongate, with base of median lobe widened; total length 4.56 mm; parameres 0.27x length of median lobe; apical area of median lobe 0.13x total length of median lobe; internal sac with sclerotized structures ( Fig. 88 View FIGURES 78–92 ).

Variation. The majority of specimens have the antennae, mouthparts, legs and last visible abdominal segment reddish but in some specimens they are brownish. Umbilicate punctures on vertex of head are variably sparse. The gular sutures are variably developed toward the neck. In two specimens, the elytra are slightly shorter than the pronotum (proportion 0.87 and 0.96x respectively).

Comparison. Renda fimetaria can be confused with R. fimetariamimus due to the fine punctures on the pronotum, black body, conically elongate apical maxillary palpomere, moderately, apically widened apical labial palpomere, temple with superior and inferior temporal carinae, and the pronotum without depressed areas. Renda fimetariamimus is distinguished by the oval head that is posteriorly narrowed, dense umbilicate punctures on the dorsal surface, a clearly convex ventral surface, shorter eyes, and the presence of a small spine on the median internal area of the parameres.

Remarks. The three syntype specimens agree with the locality data of the original description ( Sharp, 1876) and of them the male was designated as a lectotype to avoid future confusions with similar species, as R. fimetariamimus .

Geographic distribution. Brazil, Colombia ( Herman, 2001), Paraguay and Peru (first national records).
