sp. nov.

Schizoptera (Odontorhagus) simpla View in CoL , n. sp.

( Figs 3 View FIGURE 3 , 6 View FIGURE 6 M – W and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the flat head, the large eyes, the weakly asymmetrical subgenital plate, small, tab-like process of the subgenital plate, the differentiated left lateral margin of the subgenital plate, the w-shaped left paramere, and the plate-like dorsal fold of the anophore.

Description. Male: length: 1.41–1.46 mm; body broadly ovoid; COLORATION: general coloration light brown; fuscous patch absent; Sc+C concolorous with remainder of hemelytra ( Fig. 3 View FIGURE 3 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: flat in ventral view ( Fig. 3 View FIGURE 3 ); eyes about as wide as 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, with left lateral margin differentiated ( Fig. 6S View FIGURE 6 M – W ); lateral process small, stout and tab-like ( Fig. 6S View FIGURE 6 M – W ); tVII rectangular; tVIII rectangular and sclerotized; length of tVIII about 2/3 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description; lp as in subgeneric description, w-shaped in dorsal view; rca slender and hook-shaped; lca small, about 1/3 length of rca, with two processes ( Fig. 6S View FIGURE 6 M – W ); vesica uniformly thin with a needlelike tip, forming almost two coils; anophore as in subgeneric description with flat, plate-like dorsal fold ( Fig. 6S View FIGURE 6 M – W ).

Female: length 1.44–1.46 mm; general habitus as in male.

Distribution. Known from Heredia and Puntarenas provinces in Costa Rica ( Fig. 7).

Etymology. Named for the simple subgenital plate, and relatively simplistic genitalic structures after the Latin “simplus” meaning simple.
