Renda palpalis View in CoL sp. nov.

Type material ( 1 specimen). Holotype, female: “ PERU: Cuzco Dept., Consuelo, Manu rd. , km 165, 12-X- 1982 / FMHD #82-375, ex leaf litter, L. E. Watrous & G. Mazurek ” ( FMNH).

Description. Total length 17.1 mm. Body black, shining with antennomeres 4–11, maxillary and labial palpi, and tarsi red; and genital segment yellow.

Head. Ovally elongate (similar to Fig. 17 View FIGURES 11–19 ); 1.35x as long as wide; dorsal surface slightly convex on vertex; ventral surface convex; dorsal surface with dense, umbilicate punctures, becoming sparser on vertex; ventral surface with moderately dense, unevenly distributed, umbilicate punctures separated by 2–3x their width ( Fig. 23 View FIGURES 20–24 ); temple flattened with dense, umbilicate punctures ( Fig. 28 View FIGURES 25–34 ); eyes 0.27x as long as head, interocular distance 0.67x cephalic width (at eye level); first antennomere 1.82x as long as antennomeres 2–3 combined, apical antennomere 0.90x 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 ), 1.42x as long as preapical palpomere; apical labial palpomere securiform ( Fig. 46 View FIGURES 35–46 ), twice as long as preapical palpomere.

Thorax. Pronotum 1.55x as long as wide; 1.1x as wide as head; with dense, conspicuous, non-umbilicate punctures, punctures wider than those on elytra and abdomen; with smooth, wide longitudinal area; without depressed areas at each side of posterior third ( Fig. 52 View FIGURES 47–52 ). Elytra 1.05x as long as pronotum, with fine setae as dense as those on head. Prosternum with fine setae sparser than those on meso and metasternum.

Abdomen. Almost as wide as elytra; covered with fine setae denser than those on rest of body.

Aedeagus. Unknown.

Variation. Unknown.

Comparison. Renda palpalis is similar to R. ophthalmica and R. julietae in the securiform apical labial palpomere and similar pronotal punctation. It can be distinguished from R. ophthalmica by the oval head, the elongate body, the shorter eyes and by the pronotum without depressed areas (while R. ophthalmica has an almost quadrate head, shorter body, large eyes and pronotum with a depressed area at each side of the posterior third). It is distinguished from R. julietae by the absence of temporal carinae and presence of an flattened area on the temple of head, the head slightly narrowed posteriorly, the apical maxillary palpomere 1.42x as long as preapical palpomere and by the conspicuous punctures on the pronotum (while R. julietae has superior and inferior temporal carinae on the temple of head, delimiting a flattened area, ovate head not narrowing posteriorly, the apical maxillary palpomere 1.5x as long as preapical palpomere and punctures less conspicuous on the pronotum).

Etymology. The species name is derived from the Latin word “palpus” and refers to the securiform apical labial palpomere.
