Schizoptera (Odontorhagus) radicata  , n. sp.

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

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus)  by the rounded head, the weakly asymmetrical subgenital plate, the bifurcating, root-shaped process of the subgenital plate, the bifurcating right conjunctival appendage, the ladle-shaped right paramere, and the rectangular dorsal process of the left paramere.

Description. Male: length: 1.36–1.39 mm; body broadly ovate; COLORATION: general coloration dark brown; fuscous patch covering more than 1/2 of wing membrane; Sc+C distinctly lighter than remainder of hemelytra ( Fig. 3View FIGURE 3). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: slightly rounded in ventral view ( Fig. 3View FIGURE 3); eyes about 1/3 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; process of subgenital plate stem-like with a bifurcating tip ( Fig. 6QView FIGURE 6 M – W); tVII rectangular; tVIII rectangular and sclerotized; length of tVIII about 1/3 length of tVII. GENITALIA: py as in subgeneric description; rp ladle shaped, with a uniformly thin stem and rounded base; lp as in subgeneric description, with an elongate, rectangular dorsal process; uniformly thick, with a bifurcating tip; lca small, about 1/5 length of lca, with a rounded triangular tip ( Fig. 6QView FIGURE 6 M – W); vesica uniformly thin with a needlelike tip; anophore as in subgeneric description.

Female: Unknown.

Distribution. Known from northern and southern Costa Rica ( Fig. 7).

Etymology. Named for the root-like shape of the subgenital plate process after the latin “radicatus” meaning rooted.
