Redescription. Total length 18.7–22.5 mm. Body shining black, with first three antennomeres, mouthparts and tarsi reddish brown. Body covered with dense setae.

Head. Oval ( Fig. 12), 1.36x as long as wide; dorsally and ventrally slightly convex; dorsal surface with dense umbilicate punctures, extending near to anterior margin; ventral surface with dense umbilicate punctures separated by twice or less their width ( Fig. 24); tempora with inferior temporal carina and a flattened to slightly concave area ( Fig. 32); eyes 0.28x length of head, interocular distance 0.64x width of head; first antennomere nearly twice length of antennomeres 2–3 combined, apical antennomere 0.93x length of antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54); mandibles with external channel; apical maxillary palpomere elongate ( Fig. 38), 1.68x length of preapical palpomere; apical labial palpomere slightly widened and flattened towards apex ( Fig. 44), and nearly twice as long as preapical palpomere.

Thorax. Pronotum 1.5x as long as wide; 1.10x as wide as head; with dense umbilicate punctures, except for narrow longitudinal impunctate area ( Fig. 49); posterior half of pronotum without depressed areas. Elytra as long as pronotum; elytral disc with dense setiferous punctures. Prosternum with setae less dense than those of meso and metasternum.

Abdomen. With pale, long setae that are denser on lateral and posterior borders than other areas; fourth to last visible segments with long, pale setae medially; pregenital sternite of male apically sinuate.

Aedeagus. Ovally elongate, with base of median lobe widened; total length 3.55 mm; parameres 0.39x length of median lobe; apical area of median lobe 0.14x as long as total length of median lobe; internal sac with sclerotized structures ( Fig. 67).

Variation. Several specimens have the first three antennomeres, mouthparts and tarsi black; the inferior temporal carina of the head can be slightly visible to inconspicuous; umbilicate punctures on the ventral surface of head can be dense to very dense; some specimens have the vertex of the head convex.

Comparison. Renda flagellicornis   can be confused with the remaining members of the “formicaria” species group. It can be distinguished from R. profundepunctata   , R. sharpi   and R. glabrinotum   by its oval head, while the last three species have a posteriorly narrowed oval head; it can be separated from R. brachyptera   and R. bicarinata   by the presence of a inferior temporal carina on the head, while R. brachyptera   does not have carinae and R. bicarinata   has both superior and inferior carinae. Renda flagellicornis   can be distinguished from R. grandipenis   by the ventral surface of head with dense umbilicate punctures separated by less than twice their width and a small aedeagus, with large parameres; while R. grandipenis   has the ventral surface of head with sparser umbilicate punctures separated by 2–3x their width and an elongate aedeagus with short parameres. It is especially difficult to distinguish R. flagellicornis   from R. formicaria   , which can also be sympatric; R. flagellicornis   has an elongate, robust, black, shining body with sparser brown setae; the scutellum and surrounding area have only a few long black setae that contrast with the remaining setae of the elytra; the median area of the temple of the head is slightly concave; and the aedeagus is large and wide, internal sac with sclerotized structures. In contrast, R. formicaria   has a shorter, less robust body, with a reddish brown color, principally due to the high density of pale setae (mainly on elytra and abdomen); the scutellum and surrounding area are with dense black long setae that contrast with the remaining pale setae of the elytra; the median area of the temple of head is flattened; the aedeagus is smaller and pear-shaped, and the internal sac with moderately visible sclerotized structures.

Remarks. The type specimens of R. flagellicornis   and R. funebris   were compared and dissected, and they were found to be identical in form and measurements of the aedeagus as well as the remaining characters of external morphology. Renda funebris   is proposed as a junior synonym of R. flagellicornis   . The designation of lectotypes (males) was necessary for the unambiguous proposal of the new synonymy. Syntypes of each species, which have the minimal information (countries and collectors) agree with their original descriptions ( Nordmann, 1837; Sharp, 1876).

Geographic distribution. This species was recorded previously from Surinam and Brazil ( Herman, 2001). It is recorded here for the first time from Argentina, Bolivia, Colombia, Ecuador and Peru.
