Description. Male: length: 1.41–1.46 mm; body broadly ovate; COLORATION: general coloration light brown; fuscous patch covering less than 1/2 of wing membrane; Sc+C distinctly lighter than remainder of hemelytron ( Fig. 3View FIGURE 3). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: slightly concave in ventral view ( Fig. 3View FIGURE 3); eyes wider than synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein distinctly curving anteriorly toward wing margin, anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI without process on posterior margin; subgenital plate weakly asymmetrical; process of subgenital plate short and thumb-shaped ( Fig. 5LView FIGURE 5 A – L); tVII rectangular; tVIII weakly trapezoidal and sclerotized; length of tVIII about 1/2 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with a long, narrow stem and blunt tip and a medial dorsal flap; lp as in subgeneric description, with two visible triangular dorsal processes; rca narrow and thin, mostly obscured by vesica; lca with three finger-like processes ( Fig. 5LView FIGURE 5 A – L); vesica with a thick base, and uniformly thin and tubular apex, almost forming two coils; anophore as in subgeneric description, with a short blunt process on dorsal wall ( Fig. 5LView FIGURE 5 A – L).

Female: length 1.44–1.46 mm; general habitus as in male.

Distribution. Known from the western region of northern South America from two localities in Colombia (Cauca and Boyacá departments) and one locality in the Napo province in Ecuador ( Fig. 7).
