Redescription. Total length 18.3–21.0 mm. Body black, shining, with antennae, mouthparts, tarsi and genital abdominal segment reddish brown. Body densely covered with long, pale setae.

Head. Oval (similar to Fig. 11 View FIGURES 11–19 ), 1.38x as long as wide; dorsal and ventral surface slightly convex; dorsal surface with dense umbilicate punctures; ventral surface with dense umbilicate punctures separated by less than twice their width ( Fig. 24 View FIGURES 20–24 ); temple flattened ( Fig. 28 View FIGURES 25–34 ); eyes 0.25x as long as head, interocular distance 0.66x cephalic width; first antennomere 1.91x length of antennomeres 2–3 combined, apical antennomere as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54 View FIGURES 53–61 ); mandibles with external channel; apical maxillary palpomere elongate ( Fig. 38 View FIGURES 35–46 ), 1.80x as long as preapical palpomere; apical labial palpomere moderately wide and flattened toward apex ( Fig. 44 View FIGURES 35–46 ), nearly twice as long as preapical palpomere.

Thorax. Pronotum 1.5x as long as wide; 1.08x as wide as head; with dense umbilicate punctures, with longitudinal impunctate area wider in anterior third than in posterior half (very narrow, but visible; Fig. 49 View FIGURES 47–52 ); without depressed areas on basal half. Elytra as long as pronotum, densely covered with fine setae. Prosternum with sparser setae than on mesosternum and metasternum.

Abdomen. Homogeneous and densely covered with long, pale setae.

Aedeagus. Pear-shaped (lateral margins of median lobe convex); total length 3.0 mm; parameres 0.33x as long as median lobe; apical area of median lobe 0.20x total length of median lobe; internal sac with moderately visible sclerotized structures ( Fig. 68 View FIGURES 62–77 ).

Variation. Great variation in total length (18.3 to 21.0 mm). Antennae, mouthparts and tarsi are red in a majority of specimens but 3 of 10 specimens are almost entirely black. In some specimens the genital segment is brown to black.

Comparison. Renda formicaria can be confused primarily with R. flagellicornis , but the main differences are discussed in the remarks under that species.

Remarks. As it was not possible to study any type specimens (Cayenne) of R. formicaria (not located in the Muséum National d’Histoire Naturelle, Paris), it is difficult to determine the identity of this species. Specimens previously identified as R. formicaria by Nordmann, Erichson and Sharp contain individuals of R. flagellicornis , R. pubescens and R. bicarinata n. sp., so it is clear that some of these species could be synonyms of R. formicaria , as this name is older. Renda bicarinata can probably be dismissed because its geographic distribution is restricted mainly to Costa Rica and Panama (with only two records for Ecuador). Renda flagellicornis is distributed from Colombia through the west of South America but it is possible that in some places it is sympatric with R. formicaria . Based on their congruent Amazonian distribution, principally toward the east of South America including British Guiana, R. pubescens is considered a junior synonym of R. formicaria . Additionally, the name “ formicaria ” refers to some similarity of the studied species with ants, and without doubt R. pubescens is most similar to ants due to a great density of long and pale setae. The lectotype designation (male) for Araeocnemus pubescens was necessary due to the present proposal of synonymy with R. formicaria . The four syntype specimens of R. pubescens agree with the data of the original description: “Brasilia meridionali. D. Sello” ( Nordmann, 1837).

Geographical distribution. This species was recorded previously from Brazil, Colombia, French Guiana, Guyana, Peru and Venezuela ( Herman, 2001). The record from Costa Rica ( Herman, 2001) corresponds to R. bicarinata sp. nov. It is recorded here for the first time from Argentina, Paraguay and Trinidad.
