Description: (holotype male). Total length 6.27. General color brown, except base and apex of scapus, pedicellus, and flagellomeres; a wide band on profemora; apex of meso- and metafemora; posterior lobe of pronotum and posterior process of scutellum darker; hemelytra with dark maculae ( Fig. 2 ), veins pale, diffuse dark spots on segments 3–6 laterally.

Head. Length 0.86, width 0.64, antocular region length 0.38, postocular length 0.35. Eyes width 0.22, interocular space 0.14. Posterior region globose with a longitudinal deep furrow and decumbent setae. Anterior margin, genae, and gula with one pair of setiferous tubercles. Rostrum: article I: 0.42, article II: 0.32, article III: 0.29. Articles I and II with a pair of setiferous tubercles and decumbent setae. Antenna: scapus: 2.00, pedicellus: 1.13, basiflagellomere: 1.00, distiflagellomere: 1.07.

Thorax. Pronotum: Anterior pronotal lobe length 0.77, width 0.77; posterior pronotal lobe length 0.51, width 1.02. Lateral processes of collar protruded, rounded. Anterior lobe with two pairs of humps, one pair near anterior margin and one pair near posterior margin; mid- and posterior regions strongly depressed. Posterior lobe sub-trapezoidal, lateral margins rounded, anterior and posterior margins slightly concave, with scattered short erect setae. Posterior process of scutellum with a long erect spine, post-scutellum with a short erect spine, and metanotum with a long erect spine. Propleura with scattered setae, meso- and metapleurae with abundant decumbent setae. Prosternal processes with two pairs of spiniferous tubercles, dorsal ones larger than ventral. Legs: procoxae with long setiferous tubercle, pro-trochanters with two setiferous tubercles. Profemora enlarged ( Fig. 1 ) bearing nine setiferous tubercles on inner surface and a row of small spines on ventral surface (first two setiferous tubercles short, the others short and long), with erect and semierect setae more abundant on ventral surface. Protibiae slightly curved, with four long setiferous tubercles on inner surface intermixed with abundant semierect setae, and a small subapical spine. Tarsi three-segmented. Mid- and posterior legs long and slender, with abundant short decumbent setae and sparse long erect setae. Hemelytra ( Fig. 2 ): Length 4.33.

Abdomen. Length 3.43. Elongate and slender, with abundant short decumbent setae on ventral region. Male genitalia: Pygophore ellipsoidal, posterior process spiniform, elongate ( Fig. 3 ); parameres slender, apical region curved, apex acute ( Figs. 4– 5 ).

(Paratype female).Total length: 6.67. Head. length: 0.86, width: 0.66; antocular space 0.38, postocular space 0.32; width of eye: 0.21; interocular space: 0.16. Rostrum: article I: 0.38, article II: 0.32, article III: 0.29. Antenna: scapus: 2.20, pedicellus: 1.20, basiflagellomere: 1.27, distiflagellomere: 1.00. Pronotum. anterior lobe length: 0.74, width: 0.64; posterior lobe length: 0.64, width: 1.09. Hemelytra: length: 4.06. Abdomen. Length: 3.40.

Darker than male. With same coloration pattern, except base of profemora, mesopleurae, metasterna, and genital segments darker. Spines of ventral surface of profemora larger. Genital segments absent.

Material examined: holotype male, Peru, Cuzco, Pagoreni, VII-2004, at light, Williams col. ( MLP); paratype female, same data ( MLP).
