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 : 268

Schizoptera (Odontorhagus) dentata , n. sp.

( Figs 2 , 5 and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the broadly ovate body shape, the small eyes, the large tooth-like process of sVI, the tooth-shaped lateral process of the subgentinal plate, and the spatulate lca.

Description. Male: length: 1.39–1.44 mm; body broadly ovate; 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: slightly convex in ventral view ( Fig. 2 ); eyes about 1/3 as wide as synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 distinctly curving, anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI with large, tooth-like process posterior margin; subgenital plate weakly asymmetrical, with lateral margin perpendicular to lateral process slightly curving and distinctly sclerotized; process of subgenital plate “tooth” shaped, with small serration on posterior margin; tVII trapezoidal; tVIII oblong and sclerotized; length of tVIII about 3/4 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with a long, narrow stem and blunt tip; lp as in subgeneric description, with elongate dorsal finger-like process; rca narrow and thin; lca large, about 1/4 size of rca, and spatulate ( Fig. 5H ); vesica uniformly cylindrical and thin, forming almost two coils; anophore forming asymmetrical tube with prominent dorsal fold.

Female: length 1.42–1.44 mm; general habitus as in male, with a broader head.

Distribution. Known from various collection events in the Volcan Tenorio National Park in the Alajuela province in northern Costa Rica ( Fig. 7).

Etymology. Named for the tooth-like process of the posterior margin of sVI and the tooth-like process of the subgenital plate after the Latin “ dentata ” meaning toothed.
