Description. Total length 11.5–14.7 mm. Body shining black, with antennae, mouthparts and tarsi reddish brown and last 1 or 2 antennomeres red.

Head. Ovally quadrate ( Fig. 19 View FIGURES 11–19 ); 1.14x as long as wide; dorsally and ventrally convex; dorsal surface with very dense, umbilicate punctures, slightly sparser on vertex (especially on convex area); ventral surface with sparse, umbilicate punctures separated by most than 3x their width ( Fig. 22 View FIGURES 20–24 ); temple with inferior temporal carina and a deep, concave area ( Fig. 32 View FIGURES 25–34 ); eyes 0.39x as long as head, interocular distance 0.57x cephalic width (at eye level); first antennomere 2.22x as long as antennomeres 2–3 combined, apical antennomere 1.07x as long as antennomeres 9–10 combined; labrum moderately bilobed ( Fig. 54 View FIGURES 53–61 ); with mandibular external channel; apical maxillary palpomere conically elongate ( Fig. 39 View FIGURES 35–46 ), twice as long as preapical palpomere; apical labial palpomere securiform, with apical sensiles ( Fig. 46 View FIGURES 35–46 ), almost twice as long as preapical palpomere.

Thorax. Pronotum 1.38x as long as wide; 1.07x as wide as head; with fine, dense punctures, except for smooth, wide longitudinal area; with depressed area at each side of posterior third slightly to moderately visible ( Fig. 51 View FIGURES 47–52 ). Elytra 1.12x as long as pronotum; with fine setae as dense as those on head and pronotum, setae slightly paler and longer than other species of this group. Prosternum with fine setae, slightly sparser than those on meso and metasternum.

Abdomen. Borders of segments densely covered with pale setae; medial area of each segment covered with setae as in rest of body.

Aedeagus. Ovally elongate; total length 1.6 mm; with slightly asymmetrical parameres, 0.37x as long as median lobe; apical area of median lobe 0.24x total length of median lobe, internal sac with weakly sclerotized structures ( Fig. 92 View FIGURES 78–92 ).

Variation. In addition to the variation in total length, the last 1 or 2 antennomeres vary in color from brown to red to yellow.

Comparison. Renda ophthalmica is distinguished from other species except R. julietae and R. palpalis by the conical apical maxillary palpomere and the securiform apical labial palpomere. It is distinguished from R. julietae by its ovally square head, the inferior temporal carina and a deep, concave area on the temple of the head, and by the larger eyes (while R. julietae has an oval head, two temporal carinae on the temple of the head, without a concave area, and the smaller eyes). The differences between R. palpalis and R. ophthalmica are commented on the remarks for R. palpalis .

Etymology. The species name is derived from the Latin word “ophtalmus” and refers to the large eyes of this species.
