Trap, Qd 17” ( SEMC) GoogleMaps   . Paratypes: “ Coroico, BOLIVIA / Standing in NHM as P. pubescens   ?” (1♀, BMNH)   . “ PANAMA: Panama Pr. Campana, 850 m, 8°40´N, 79°56´W, 6 sept.´70. Stockwell” (1♂, BMNH) GoogleMaps   . “ PERU: Madre de Dios Dept., Tambopata , 28-X-1982 / FMHD # 82-405, ex forest canopy, T. L. Erwin ” (1♀, FMNH)   .

Description. Total length 12.5–14.7 mm. Body black, with antennomeres 4–11, palpi, tarsi and genital segment reddish brown.

Head. Oval, slightly posteriorly narrowed (similar to Fig. 14); 1.38x as long as wide; slightly convex dorsally and ventrally; dorsal surface with dense umbilicate punctures and some smooth areas on vertex; ventral surface with sparse, umbilicate punctures separated by more than 3x their width ( Fig. 22), combined with fine, dense setae; temple with inferior temporal carina and a slightly deep, concave area ( Fig. 32); eyes 0.28x as long as head, interocular distance 0.66x cephalic width (at eye level); first antennomere 1.84x as long as antennomeres 2–3 combined, apical antennomere 1.02x as long as antennomeres 9–10 combined; labrum moderately bilobed ( Fig. 54); with mandibular external channel; apical maxillary palpomere elongate ( Fig. 38), 1.93x as long as preapical palpomere; apical labial palpomere moderately widened at apex ( Fig. 44), almost twice as long as preapical palpomere.

Thorax. Pronotum 1.55x as long as wide; 0.96x cephalic width; with fine, dense punctures, except for wide longitudinal impunctate area ( Fig. 52); with depressed area at each side of posterior third poorly developed. Elytra 1.13x as long as pronotum, with fine setae as dense as those on head and pronotum. Prosternum with fine setae as dense as those on meso and metasternum.

Abdomen. Covered with setae slightly denser than those on remaining body; borders of each segment with setae paler and longer than on internal area.

Aedeagus. Ovally elongate, with base of median lobe widened; total length 3.46 mm; parameres 0.26x length of median lobe; apical area of median lobe 0.14x total length of median lobe; internal sac with sclerotized structures ( Fig. 85).

Variation. In females, body length is greater than in males, the vertex is without smooth areas, the temple without carinae, the head has no depressed internal area, and the ventral surface of the head has moderately dense, umbilicate punctures combined with fine punctures.

Comparison. This species can be confused with R. clavicornis   , R. cariniventris   and R. pronotalis   due to the length of the apical maxillary palpomere, but it is easily separated from them by the slightly, posteriorly narrowed head, the inferior temporal carina weakly developed, the slightly convex ventral surface of the head, the elytra longer than pronotum and by the widened base of the median lobe of the aedeagus.

Etymology. It is with great pleasure that I dedicate the name of this species to Martin Brendell (former curator of Staphylinidae   of the Natural History Museum in London) for his facilitation in specimen loans and for his friendship.

Geographic distribution. Bolivia, Panama and Peru.
