Renda fimetariamimus View in CoL sp. nov.

Type material ( 1 specimen). Holotype, male: “ COLOMBIA: Vaupes, Mitu , 11.V.1974, M. Cooper, B. M. 1974-327” ( BMNH).

Description. Total length 13.5 mm. Body black, with antennae, mouthparts, legs and genital segment reddish brown; central area of pronotum with reddish brown spot.

Head. Oval, posteriorly narrowed (similar to Fig. 14 View FIGURES 11–19 ); 1.41x as long as wide; dorsal surface is slightly convex at vertex; dorsal surface with very dense dorsal umbilicate punctures, slightly dense ventrally separated by 3x or more their width ( Fig. 22 View FIGURES 20–24 ) and unevenly distributed; ventral surface with gular sutures clearly convex; temple with superior and inferior temporal carinae and a concave area ( Fig. 34 View FIGURES 25–34 ); eyes 0.27x as long as head, interocular distance 0.61x as wide as cephalic width (at eye level); first antennomere 1.91x as long as antennomeres 2–3 combined, apical antennomere 1.07x as long as antennomeres 9–10 combined; labrum weakly bilobed ( Fig. 54 View FIGURES 53–61 ); with mandibular external channel; apical maxillary palpomere conically elongate ( Fig. 39 View FIGURES 35–46 ), 1.75x as long as preapical palpomere; apex of apical labial palpomere slightly widened and flattened ( Fig. 44 View FIGURES 35–46 ), more than 1.75x as long as preapical palpomere.

Thorax. Pronotum 1.67x as long as wide; as wide as head; with dense, fine punctures, except for wide, longitudinal impunctate area ( Fig. 52 View FIGURES 47–52 ); without depressed areas at each side of posterior third. Elytra as long as pronotum, with punctures as those on pronotum, punctures slightly denser at anterior and posterior borders, but setae not forming a fascia. Prosternum with fine setae as dense as those on meso and metasternum.

Abdomen. Densely covered with setae as in rest of body, setae on borders of segments paler and longer than those on the medial area of each segment.

Aedeagus. Ovally elongate, with base of median lobe widened; total length 3.56 mm; parameres 0.25x as long as median lobe, with a small spine in the middle of internal margin of each paramere; apical area of median lobe 0.16x as long as total length of median lobe; internal sac with sclerotized structures ( Fig. 89 View FIGURES 78–92 ).

Variation. Unknown.

Comparison. This species is similar to R. fimetaria in the temple with superior and inferior temporal carinae and a concave area and in the pronotum without depressed lateral areas. Renda fimetariamimus is distinguished from R. fimetaria by the posteriorly narrowed head, short eyes and aedeagus with a spine on the parameres; while R. fimetaria does not have a head narrowing posteriorly, it has large eyes and a distinct aedeagus, without spine in the parameres.

Etymology. The species name is derived from the Latin word “mimus” and refers to the great similarity of this species with R. fimetaria .

Geographic distribution. Colombia (known only from the type locality) .
