(Figs 2, 5 and 7)
Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by small body size, ovoid body shape, the dark brown coloration, the rounded process on the posterior margin of sVI, the angular shape of the subgenital plate, the blade-shaped lateral process of the subgenital plate, the small and blunt-tipped right paramere, and the claw-shaped left conjunctival appendage.

Description. Male: length: 1.22–1.29 mm; body ovoid. COLORATION: general coloration dark brown; fuscous patch covering more than 1/2 of wing membrane; Sc+C distinctly lighter than remainder of hemelytra.
SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: rounded in ventral view (Fig. 2); eyes about 1/2 as wide as synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein straight, anterior costal cell triangular. ABDOMEN: as in subgeneric description; stVI with rounded process on posterior margin; subgenital plate distinctly asymmetrical, with posterior margin lateral process forming a right angle with longitudinal margin of subgenital plate; process of subgenital plate of blade-like (Fig. 5B); tVII rectangular; tVIII parallel-sided; length of tVIII about 3/4 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with a short, curving stem and rounded tip; lp as in subgeneric description, tab-shaped in dorsal view (Fig. 5B); rca thin and curving; lca small, about than 1/4 length of rca and claw-shaped; vesica uniformly cylindrical and thin, forming more than three coils; anophore as in generic description.
Female: length: 1.27–1.29 mm; general habitus as in male.
Distribution. Known from two localities in Colombia: Gorgona National Park in the Cauca department and the Amacayacu National Park in Amazonas, and from one locality in the Orellana province in Ecuador.
Etymology. Named for the right angle formed by the lateral process and the longitudinal margin of the subgenital plate after the Latin “ angularis ” meaning angular.
