Description. Total length 15.2–16.1 mm. Body black, with antennomeres 4–11, mouthparts, tarsi, and apex of fifth visible abdominal segment to the genital segment red.

Head. Oval to slightly rounded ( Figs. 10, 13); 1.25x as long as wide; dorsally convex and slightly convex ventrally; dorsal surface with umbilicate punctures and some smooth areas; ventral surface with moderately dense, unevenly distributed, umbilicate punctures separated by 2–3x their width ( Fig. 23); temple with superior and inferior temporal carinae poorly developed and a flattened internal area ( Fig. 33); eyes 0.29x as long as head, interocular distance 0.66x cephalic width (at eye level); first antennomere 1.76x as long as antennomeres 2–3 combined, apical antennomere as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54); with mandibular external channel; apical maxillary palpomere conically elongate ( Fig. 39), 1.57x as long as preapical palpomere; apical labial palpomere securiform, with visible sensiles ( Fig. 46), almost twice as long as preapical palpomere.

Thorax. Pronotum 1.52x as long as wide; as wide as head; with fine, dense punctures, except for smooth, wide longitudinal area; without depressed areas at lateral side of posterior third ( Fig. 52). Elytra as long as pronotum, fine setae as on head and pronotum. Prosternum densely covered with fine setae as dense as those on meso and metasternum.

Abdomen. Covered with setae slightly denser than on rest of body.

Aedeagus. Elongate; total length 2.22 mm; with parameres directed toward right side of median lobe in ventral view; parameres 0.3x as long as median lobe; apical area of median lobe 0.15x total length of median lobe; internal sac without sclerotized structures ( Fig. 91).

Variation. The apex of the last antennomere varies from red to yellow and the legs vary from almost black to reddish brown. The extent of the smooth areas on the dorsal surface of the head is variable.

Comparison. This species is similar to R. ophthalmica and R. palpalis because of their securiform apical labial palpomere. Distinguishing remarks can be found under those species.

Etymology. The name of this species is dedicated with great pleasure to my wife and my newborn baby, Julieta Asiain and Julieta Márquez respectively, in gratitude of Julieta Asiain´s help in the preparation of some drawings, revision of the manuscript, preparation of some specimens, and, most importantly, for our love and our daughter.

Geographic distribution. Costa Rica, Honduras and Mexico.
