Description. Total length 11.9–14.5 mm. Body black, shining with antennomeres 4–11, palpi, tarsi and genital segment reddish brown. Body densely and almost evenly setose.

Head. Ovally quadrate, slightly wider at posterior angles, with posterior margin slightly convex (similar to Fig. 19 View FIGURES 11–19 ); 1.12x as long as wide; dorsal surface slightly convex, ventral surface clearly convex, mainly on gular sutures; dorsal and ventral surface with very dense, umbilicate punctures separated by less than twice their width ( Fig. 24 View FIGURES 20–24 ); temple convex ( Fig. 27 View FIGURES 25–34 ); eyes 0.26x as long as head, interocular distance 0.69x cephalic width; first antennomere 1.84x as long as antennomeres 2–3 combined, apical antennomere 0.91x as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54 View FIGURES 53–61 ); with mandibular external channel; apical maxillary palpomere conical ( Fig. 40 View FIGURES 35–46 ), 1.21x as long as preapical palpomere; conical apical labial palpomere ( Fig. 45 View FIGURES 35–46 ).

Thorax. Pronotum 1.38x as long as wide; as wide as head; with dense fine punctures, except for wide longitudinal impunctate area; with depressed area slightly visible at each side of posterior third ( Fig. 51 View FIGURES 47–52 ). Elytra as long as pronotum, with setae as dense as those on head and pronotum. Prosternum with fine setae as dense as those on mesosternum; metasternum with denser setae than those on pro and mesosternum.

Abdomen. With long, pale setae on margins and short and brown setae on each segment.

Aedeagus. Elongate; total length 1.6 mm; with parameres slightly asymmetrical, 0.4x length of median lobe; apical area of median lobe 0.27x total length of median lobe; internal sac with weakly sclerotized structures ( Fig. 79 View FIGURES 78–92 ).

Variation. One of the three specimens has antennomeres 4–11 reddish. The head varies from nearly flat to slightly convex dorsally and the depressed areas of the pronotum are poorly developed to inconspicuous.

Comparison. This species can be confused with R. minor , R. mesoamericana and R. ophthalmica and their distinguishing characteristics can be found in the remarks for those species. Additionally, R. lescheni is similar to R. brasiliana , among other characteristics, in that the head is clearly convex ventrally. However, it can be distinguished by the reddish brown last visible abdominal segment and slightly asymmetrical parameres of the aedeagus. In R. brasiliana the two last visible abdominal segments are yellow, and the parameres of the aedeagus are symmetrical.

Etymology. I take pleasure in dedicating the name of this species to Richard A. B. Leschen ( New Zealand Arthropod Collection, Landcare Research, Auckland, New Zealand), the collector of several specimens of Renda , and for his contribution to the study of Staphylinidae .
