Renda pronotalis View in CoL sp. nov.

Type material (2 specimens). Holotype, male: “ ECUADOR: Napo, Scyasuni , 250 m. 7–14 Sept 1997, F. Maza / Ex: interception trap ” ( QCAZ) . Paratype, female: “ Ecuador : Napo reg., Tiputini Res. Stat., 220 m. 5– 25.IX.00, 0°38´S, 76°9´W / Flight intercept trap, D. J. Inwars & K. A. Jackson, BMNH (E) 2000-194” (1♀, BMNH) GoogleMaps .

Description. Total length 13.2–13.4 mm. Body black, with antennomeres 4–11, mouthparts, tibiae, tarsi and genital segment red to reddish brown.

Head. Ovally quadrate (similar to Fig. 19 View FIGURES 11–19 ); dorsally and ventrally convex; 1.2x as long as wide; with dense, umbilicate punctures on dorsal surface and some smooth areas on vertex and front; ventral surface with slightly dense, umbilicate punctures separated by more than 3x their width ( Fig. 22 View FIGURES 20–24 ); temple with superior and inferior temporal carinae and a concave area ( Fig. 34 View FIGURES 25–34 ); eyes 0.33x as long as head, interocular distance 0.6x as wide as cephalic width; first antennomere 1.85x as long as antennomeres 2–3 combined, apical antennomere as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54 View FIGURES 53–61 ); with mandibular channel; apical maxillary palpomere elongate ( Fig. 38 View FIGURES 35–46 ), 2.0x as long as preapical palpomere; apical labial palpomere with slightly widened apex ( Fig. 44 View FIGURES 35–46 ), almost twice as long as preapical palpomere.

Thorax. Pronotum 1.47x as long as wide; 1.07x as wide as head; with fine, dense punctures, except for smooth, wide longitudinal area ( Fig. 52 View FIGURES 47–52 ); with a poorly developed depressed area at each side of posterior third. Elytra as long as pronotum, with fine setae sparser than those on pronotum. Prosternum with fine setae sparser than those on meso and metasternum, with a longitudinal, fine carina on the posterior third.

Abdomen. Covered with setae as dense as those on head and pronotum.

Aedeagus. Ovally elongate; total length 1.75 mm; parameres 0.36x as long as median lobe; apical area of median lobe 0.21x total length of median lobe; internal sac with weakly sclerotized structures ( Fig. 90 View FIGURES 78–92 ).

Variation. The smooth areas on the vertex and front of head are variable in size and the umbilicate punctures on the ventral surface of the head vary in density from moderate to sparse.

Comparison. This species can be distinguished from the remaining species of this group by the ovally square head, the sparse umbilicate punctures on the ventral surface of the head, the slightly wide punctures on the pronotum and by the pronotum that is longer than the head (1.24x).

Etymology. The species name is derived from the Latin words “pro” and “notum” and refers to the conspicuous punctures on the pronotum and to the fact that this structure is longer than the head.

Geographic distribution. Ecuador.
