Body black, shining with antennomeres 4–11, palpi, tarsi and genital segment reddish. Head . Oval ( Fig. 8 ); 1.2x as long as wide; dorsally slightly convex and ventrally clearly convex; dorsal surface with very dense, umbilicate punctures; ventral surface with moderately dense, umbilicate punctures separated by 2–3x their width ( Fig. 23 ), almost evenly distributed; temple with superior and inferior temporal carinae that delimit a deep, concave area ( Fig. 34 ); eyes 0.3x as long as head, interocular distance 0.65x cephalic width; first antennomere 1.73x as long as antennomeres 2–3 combined, apical antennomere 1.06x as long as antennomeres 9–10 combined; labrum moderately bilobed ( Fig. 54 ); with mandibular external channel; apical maxillary palpomere elongate ( Fig. 38 ), 2.12x as long as preapical palpomere; apical labial palpomere moderately widened at apex ( Fig. 44 ), almost twice as long as preapical palpomere. Thorax . Pronotum 1.43x as long as wide; 1.03x as wide as head; with dense, fine punctures, except for wide longitudinal impunctate area ( Fig. 52 ); with depressed area at each side of posterior third poorly developed. Elytra as long as pronotum; with fine setae as dense as those on head but denser than those on pronotum. Prosternum with longitudinal, fine carina on anterior half. Abdomen . Densely covered with fine setae as dense as those on head and elytra; borders of segments with paler and longer setae than those on internal area of each segment. Aedeagus . Ovally elongate; total length 2.75 mm ; right paramere slightly shorter than left paramere; parameres 0.23x as long as median lobe; apical area of median lobe 0.11x total length of median lobe; internal sac with sclerotized structures ( Fig. 87 ). Variation. Some small specimens have a clearly convex dorsal surface of head. The apex of the last antennomere varies from reddish to yellow and the genital segment varies from brown to reddish. The longitudinal carina on the anterior half of the prosternum is variably developed. One specimen has some umbilicate punctures on the pronotum. Comparison. This species is similar to R. brendelli , R. cariniventris and R. pronotalis in the elongate apical maxillary palpomere. However, R. clavicornis is clearly distinguished from those three species by the superior and inferior temporal carinae of the head that delimit deep, concave area, by the slightly convex dorsal surface of the head, by the carina on the prosternum and by the shape of the aedeagus. Geographic distribution. Known previously from Brazil and Peru ( Herman, 2001 ); it is recorded here from Colombia , Costa Rica , Ecuador , French Guiana, Guyana , Panama and Suriname for the first time.
