 Description. Total length 15.3–18.8 mm. Body black, shining with reddish brown mouthparts, tarsi and genital segment.   
 Head. Oval, posteriorly narrowed (Fig. 15), 1.43x as long as wide; slightly convex dorsally and ventrally; dorsal and ventral surfaces with dense umbilicate punctures separated by less than twice their width (Fig. 24); temple with inferior temporal carina and a concave, slightly to moderately deep area (Fig. 32); eyes 0.28x as long as head, interocular distance 0.66x cephalic width; first antennomere 1.73x as long as antennomeres 2–3 combined, apical antennomere 0.94x as long as antennomeres 9–10 combined; labrum slightly bilobed (Fig. 54); mandibles with external channel; apical maxillary palpomere elongate (Fig. 38), 1.86x as long as preapical palpomere; apical labial palpomere moderately wide and flattened toward apex (Fig. 44), nearly twice as long as preapical palpomere.   
 Thorax. Pronotum 1.5x as long as wide; 1.12x as wide as head; with dense umbilicate punctures, with longitudinal impunctate area wide at anterior third and very narrow, but visible at posterior half; without depressed areas on posterior third (Fig. 49). Elytra as long as pronotum (0.94x), with dense setae on elytral disc. Prosternum with less density of setae than mesosternum and metasternum.   
 Abdomen. Densely covered with setae as on remainder of body.   
 Aedeagus. Pear-shaped (lateral margins of median lobe convex); total length 2.53 mm; parameres 0.37x as long as median lobe, apical area of median lobe 0.14x as long as total length, internal sac with moderately visible sclerotized structures (Fig. 71).   
 Variation. Great variation in total length (15.3–18.8 mm). The elytra in some specimens show metallic reflections and the antennae can be black or reddish brown.   
 Remarks. The species can be confused mainly with R. profundepunctata but the main differences are discussed in the remarks under that species.   
 Etymology. I take pleasure in dedicating the name of this species to D. Sharp, in gratitude for his great contribution to the knowledge of Staphylinidae.   
 Geographic distribution. Ecuador.   
1´. Species with dense umbilicate punctures on head; pronotum with dense to moderately dense fine punctures, except for wide longitudinal impunctate area (Figs. 5–10; 51, 52); body of medium to short size and apical maxillary palpomere elongate (Fig. 38), conically elongate (Fig. 39) or conical (Fig. 40).......................................................... 2  
2. Metallic species or at least with metallic reflections; apical antennomere longer than antennomeres 9–10 combined; labrum with four teeth (Fig. 55); elytra with a transversal band of long, white setae on anterior third (fascia) and on posterior border (Fig. 5)........................................................................................................... “fasciata” species group
