( Figs 3 , 6 and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the flat head, the large eyes, the distinctly asymmetrical subgenital plate, the notched lateral process of the subgenital plate, the tubular and serrated right conjunctival appendage, the supercoiled vesica, and the large aperture of the anophore.

Description. Male: length: 1.41–1.44 mm; body broadly ovate; COLORATION: general coloration brown; fuscous patch absent; Sc+C distinctly lighter than remainder of hemelytra ( Fig. 3 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: flat in ventral view ( Fig. 3 ); eyes about 2/3 wide as 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. 6M ); 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, tapering stem; lp as in subgeneric description, with two lobate dorsal processes; rca narrow and thin with a serrated base; lca large, about 1/2 length of rca with two finger-like processes ( Fig. 6M ); vesica uniformly thin and tubular, forming more than four coils; anophore as in subgeneric description, with a blunt finger-like process on dorsal wall, and a wide dorsal aperture ( Fig. 6M ).

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

Distribution. Known from the western region of northern South America from the western Colombian department of Cauca and the southwestern department of Putumayo, and from the neighboring province of Napo in northern Ecuador.

Etymology. Named after the Latin “insidiosus” meaning deceitful because of the superficial similarity to the subgenital plate of S. exacta , n. sp.
