Type material ( 1 specimen). Holotype, male: “ ECUADOR: Napo Prov. Jatun Sacha Biol. Sta. 21 km E Puerto Napo, 400 m, 7 VII 1994, Francois Génier , ex: flight intercept trap ” ( SEMC).

Description. Total length 16.8 mm. Head, abdomen and legs metallic blue; pronotum metallic violaceous; elytra near black; antennomeres 1–3, mouthparts, tarsi and genital segment reddish brown; antennomeres 4– 11 reddish, with apex of last antennomere yellow.

Head. Ovally elongate, with obtuse posterior corners (similar to Figs. 12, 14 View FIGURES 11–19 ), 1.44x as long as wide; dorsal surface slightly convex only on vertex; ventral surface clearly convex, mainly on gular sutures; dorsal surface with very dense umbilicate punctures and ventral surface with moderately dense umbilicate punctures, unevenly distributed, separated by 2–3x their width ( Fig. 23 View FIGURES 20–24 ); temple with superior and inferior temporal carinae and a slightly deep, concave area ( Fig. 34 View FIGURES 25–34 ); eyes 0.28x as long as head, interocular distance 0.65x cephalic width; first antennomere 1.81x as long as antennomeres 2–3 combined, apical antennomere 1.35x as long as antennomeres 9–10 combined; labrum with 4 teeth, central pair longer than lateral pair ( Fig. 55 View FIGURES 53–61 ); mandibular external channel poorly developed; apical maxillary palpomere conically elongate ( Fig. 39 View FIGURES 35–46 ), 1.69x as long as preapical palpomere; apical labial palpomere with apex slightly widened and flattened ( Fig. 44 View FIGURES 35–46 ), nearly twice as long as preapical palpomere.

Thorax. Pronotum long, 1.62x as long as wide; as wide as head, with fine and moderately dense punctures, except for smooth and wide longitudinal belt; with depressed area at each side of posterior third slightly visible ( Fig. 51 View FIGURES 47–52 ). Elytra 1.06x as long as pronotum; with fascia of pale, long setae as wide as scutellum and with similar setae on posterior border (similar to Fig. 5 View FIGURES 1–6 ). Prosternum transverse, with setae sparser than on meso and metasternum.

Abdomen. Covered with moderately dense, pale, long setae, that are denser than on head and pronotum.

Aedeagus. Ovally elongate, with base of median lobe narrowed; total length 3.44 mm; parameres 0.29x length of median lobe, apical area of median lobe 0.26x as long as total length of median lobe and internal sac with moderately visible sclerotized structures ( Fig. 72 View FIGURES 62–77 ).

Variation. Unknown.

Comparison. This species can be confused with the remaining species of this group. It can be distinguished from R. fulgida by its metallic blue color, while R. fulgida is black, with metallic reflections; it can be distinguished from R. simplicephala , R. fasciata and R. leprieuri by its oval head not narrowed posteriorly, in the remaining species the head is oval and narrowed posteriorly. Additionally, the aedeagus of R. cyanea is oval with a narrow base.

Etymology. The species name is derived from the Latin word “cyaneus”, and refers to the metallic blue body color of this species.

Geographic distribution. Ecuador.
