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 ) aspera n. sp. ( Figs 2 , 5 and 7 ) Diagnosis. Distinguished among species of Schizoptera ( Odontorhagus ) by the broadly ovoid body shape, the dark brown coloration, the rounded head, the small, tooth-like process on the posterior margin of sVI, the single, jagged, hitch-hikers thumb-like process of the subgenital plate, the needle-shaped right conjunctival appendage, and the bifurcating left conjunctival appendage.

Porras, 2♂ (00014769, 00014501) (INBIO). Description. Male : length: 1.43–1.49 mm ; body broadly ovoid. COLORATION: general coloration dark brown; fuscous patch covering less than 1/2 of wing membrane; Sc+C concolorous with remainder of hemelytra ( Fig. 2 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: distinctly rounded in ventral view ( Fig. 2 ); eyes about 1/3 as wide as synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein slightly curving anteriorly toward wing margin, anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI with a small, tooth-like process on posterior margin; subgenital plate weakly asymmetrical, with jagged margins a single lateral process; process of subgenital plate jagged, and shaped like a hitch-hiker’s thumb ( Fig. 5D ); tVII rectangular; tVIII weakly trapezoidal and distinctly sclerotized; length of tVIII about 3/4 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with curving stem pointed tip; lp as in subgeneric description, with a funnel-shaped dorsal process ( Fig. 5D ); rca needle-shaped; lca small, about less than 1/4 length of rca, with with a rounded base and two sharp bifurcations; vesica uniformly cylindrical and thin, forming a single coil; anophore as in subgeneric description. Female : length: 1.47–1.49 mm ; general habitus as in males. Distribution. Known from two localities in northern Costa Rica in the provinces of Limon and San Jose ( Fig. 7 ). Etymology. Named for the jagged appearance of the subgenital plate after the Latin “asper” meaning rough or coarse.
