Renda brevipennis View in CoL sp. nov.

Type material ( 1 specimen). Holotype, female: “ PERU: Cuzco Dept., Consuelo, Manu rd. , km 165, 7-X- 1982 / FMHD #82-353, ex leaf litter, L. E. Watrous & G. Mazurek ” ( FMNH).

Description. Total length 15.5 mm. Body reddish brown with red antennae, mouthparts and tarsi. The only specimen known is probably teneral.

Head. Ovally elongate (similar to Fig. 17 View FIGURES 11–19 ); 1.35x as long as wide; moderately convex dorsally on vertex and ventrally at gular sutures; dorsal surface with dense umbilicate punctures, punctures sparser on vertex and front; ventral surface with sparse umbilicate punctures separated by 3x or more their width ( Fig. 22 View FIGURES 20–24 ), almost evenly distributed; temple flattened ( Fig. 28 View FIGURES 25–34 ); eyes 0.3x as long as head, interocular distance 0.65x cephalic width; first antennomere 1.84x as long as antennomeres 2–3 combined, apical antennomere as long as antennomeres 9–10 combined; labrum weakly bilobed ( Fig. 54 View FIGURES 53–61 ); mandibular external channel poorly developed, present only on base of each mandible; apical maxillary palpomere conically elongate ( Fig. 39 View FIGURES 35–46 ), twice as long as preapical palpomere; apical labial palpomere asymmetrically conical ( Fig. 45 View FIGURES 35–46 ), twice as long as preapical palpomere.

Thorax. Pronotum 1.62x as long as wide; as long and as wide as head; with dense, fine punctures, except for wide longitudinal impunctate area; without depressed areas on posterior third ( Fig. 52 View FIGURES 47–52 ). Elytra notably shorter than pronotum (0.69x), with fine setae as dense as those on pronotum and as sparse as those on head and abdomen; wings not present (without membranous wings or damaged); prosternum with fine setae, as sparse as those on meso and metasternum.

Abdomen. Wider than head and pronotum, as wide as, or slightly wider than elytra; densely covered with fine setae that are denser than pronotum and elytra, setae of this type mainly on borders of each segment; sixth visible sternite strongly emarginate in apex.

Aedeagus. Unknown.

Variation. Unknown.

Comparison. The head shape, the apical maxillary palpomere and eyes of R. brevipennis are similar to those of R. fimetaria and R. fimetariamimus , but the former is distinguished by its very short elytra, the absence of carinae on the temple of head, the wide abdomen and the emarginated apex of the sixth visible sternite.

Etymology. The species name is derived from the Latin words “brevis” and “pennae” and refers to the short elytra of this species.

Geographic distribution. Peru.
