Redescription. Total length 14.9 to 18.0 mm. Body black, with maxillary and labial palpi, and tarsi reddish brown. Entire body densely pilose.
Head. Oval, 1.30x as long as wide; dorsally and ventrally slightly convex; dorsal surface of head with dense umbilicate punctures, with only anterior portion smooth; ventral surface of head with dense umbilicate punctures separated unevenly by 1–2x their width ( Fig. 24 View FIGURES 20–24 ); temple flattened, with similar punctures as on head disk ( Fig. 28 View FIGURES 25–34 ); eyes 0.27x as long as head, interocular distance 0.68x cephalic width; first antennomere almost twice the 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; elongate apical maxillary palpomere ( Fig. 38 View FIGURES 35–46 ), 1.83x 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 1.48x as long as wide; 1.08x as wide as cephalic width; with dense umbilicate punctures, except for narrow longitudinal impunctate area; without depressed areas on basal half ( Fig. 49 View FIGURES 47–52 ). Elytra 0.86x as long as pronotum; elytral disc with dense, pale setae, these setae shorter than those of abdomen. Prosternum with setae less dense than those of mesosternum and metasternum.
Abdomen. Long, pale setae more numerous on lateral and posterior borders of segments compared to the disc.
Aedeagus. Ovally elongate, with lateral margins of median lobe convex; total length 2.37 mm; parameres 0.34x as long as median lobe, apical area of median lobe 0.21x as long as total length of median lobe, and internal sac with weakly sclerotized structures ( Fig. 66 View FIGURES 62–77 ).
Variation. Total length (14.2–18.0 mm). One female specimen has legs, antennae and mouthparts entirely reddish brown, contrasting with the majority of specimens that have only antennomeres 4–11, mouthparts and tarsi reddish brown. Some males were observed with the right paramere of the aedeagus slightly longer than the left paramere.
Comparison. Renda brachyptera is similar to species with dense umbilicate punctures on the head and the pronotum, such as R. bicarinata , R. flagellicornis and R. formicaria ; it can be distinguished from them by their short elytra relative to the pronotum, the lack of temporal carinae on head, but with tempora flattened, and a pear-shaped aedeagus.
Remarks. Syntypes agree with the localities and countries included in the original description ( Sharp, 1885). Two paralectotypes from Panama designated by Sharp are at the same time paratypes of R. bicarinata sp. n. To establish the identity of this species and to avoid its confusion with similar species, such as R. bicarinata , one male from Guatemala was selected and designated as the lectotype because it represents adequately the species, including the aedeagus.
Geographic distribution. Mexico, Guatemala and Honduras ( Herman, 2001). The record from Panama corresponds instead to R. bicarinata ; specimens reported from Trinidad were not studied.
