Total length 13.8–19.0 mm; body black and shining, with antennae, mouthparts and tarsi reddish brown.  Head. Oval ( Fig. 11), 1.31x as long as wide; dorsal surface slightly convex; ventral surface clearly convex; with dense umbilicate punctures on dorsal and ventral surfaces separated by less than twice their width ( Fig. 24); temple with superior and inferior temporal carinae and a concave area ( Fig. 34); eyes 0.28x length of head, interocular distance 0.65x width of head measured at eye level; first antennomere nearly twice length of 2–3 combined, apical antennomere 0.94x length of antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54); mandibles with external channel; apical maxillary palpomere elongate ( Fig. 38), 1.94x length of preapical palpomere; apical labial palpomere slightly widened and flattened toward apex ( Fig. 44), almost twice as long as preapical palpomere.  Thorax. Pronotum 1.45x as long as wide, slightly wider than head (1.09x); with dense umbilicate punctures, except for narrow longitudinal impunctate area ( Fig. 49); posterior half of pronotum without depressed areas. Elytra as long as pronotum, with short setae as dense as those on head, these setae denser on pronotum and sparser on abdomen. Prosternum with setae sparser than that of meso and metasternum.  Abdomen. Covered with pale and long setae denser than elsewhere on body.  Aedeagus. Ovally elongate, with base of median lobe strongly widened; total length 2.9 mm; parameres 0.30x length of median lobe; apical area of median lobe 0.13x total length of median lobe; internal sac with weakly sclerotized structures ( Fig. 65).  Variation.Great variation in total length (13.8–19.0 mm). Body color mainly black, with antennomeres 4–11, maxillary and labial palpi, and tarsomeres reddish brown, and apex of last visible abdominal segment reddish. However, in several specimens these structures are almost black and in some specimens, the apex of the last antennomere is yellow or reddish. Punctures on cephalic ventral surface are unevenly distributed and variably dense.  Comparison. This species is similar to  R. formicariaand  R. flagellicornisin the dense umbilicate punctation of the head and pronotum and the large body size.  Renda bicarinatacan be distinguished from the two previous species by the temple with superior and inferior temporal carinae and a concave area, by the oval head and the particular characteristics of the aedeagus.   Remarks. Several specimens of  R. bicarinatahad been previously identified as  R. formicariaor as a variety, owing to the similarity of both species. Two paralectotypesof  R. brachypterafrom Panama(considered as “variation” by Sharp, 1885) are not conspecific with the lectotypeof that species, but belong to  R. bicarinata sp. n., and were designated as paratypesof that species.   Etymology.The species name is derived from the Latin word “carinae”, and refers to the two carinae on the temple of the head that delimit the concave internal area.  Geographic distribution. Costa Rica, Ecuadorand Panama. 1980-07-25 1980-07-27 1980-07-25 INBIO D.
