Leon, Stephanie & Weirauch, Christiane, 2016, Scratching the surface? Taxonomic revision of the subgenus Schizoptera (Odontorhagus) reveals vast undocumented biodiversity in the largest litter bug genus Schizoptera Fieber (Hemiptera: Dipsocoromorpha), Zootaxa 4184 (2), pp. 255-284 : 281-282

Schizoptera (Odontorhagus) trivialis , n. sp.

( Figs 4 , 6 and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the flat head, the large eyes, the small blade-like process of the subgenital plate, the cactus-shaped left conjunctival appendage, and the wide slit of the anophore.

Description. Male: length: 1.38–1.42 mm; body ovoid; COLORATION: general coloration light brown; fuscous patch absent; Sc+C concolorous with remainder of hemelytra ( Fig. 4 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: flat in ventral view ( Fig. 4 ); eyes 1 1/3 times wider than synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein distinctly curving; anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI without process on posterior margin; subgenital plate weakly asymmetrical; lateral process of subgenital plate blade shaped; ( Fig. 6V ); tVII rectangular; tVIII weakly trapezoidal; length of tVIII about 1/2 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description; lp as in subgeneric description with two blunt dorsal processess; rca uniformly thin; lca small, about 1/3 length of rca, and cactus-shaped ( Fig. 6V ); vesica uniformly thin, forming at least three coils; anophore as in subgeneric description with a prominent, elongate slit.

Female: length 1.42 mm; general habitus as in male.

Distribution. Known from three localities in the western region of northern South America: the Putumayo department in Colombia, and the Napo and Orellana provinces in Ecuador ( Fig. 7).

Etymology. Named for the ordinary, rather non-descript shape of the subgenital plate after the Latin “ trivialis ” meaning trivial or ordinary.
