Scratching the surface? Taxonomic revision of the subgenus Schizoptera (Odontorhagus) reveals vast undocumented biodiversity in the largest litter bug genus Schizoptera Fieber (Hemiptera: Dipsocoromorpha) Author Leon, Stephanie Author Weirauch, Christiane text Zootaxa 2016 4184 2 255 284 journal article 37901 10.11646/zootaxa.4184.2.2 6dce6de7-19d7-462d-a123-e94ad5135e89 1175-5326 164749 5B8F792E-EEDB-494D-9EB3-48CA6174CC6E 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.

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.
