Schizoptera (Odontorhagus) acuta  n. sp.

( Figs 2View FIGURE 2, 5View FIGURE 5 A – L, and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus)  by the elongate ovoid body shape, the dark brown coloration, the single, needle-shaped process of the subgenital plate (sVII), the flat right conjunctival appendage with a serrated ventral margin, the distinctly curving and sharp tip of the right paramere, and the large, uniformly round left paramere.

Description. Male: length: 1.25–1.30 mm; body elongate ovoid. COLORATION: general coloration dark brown; fuscous patch covering less than 1/2 of wing membrane; Sc+C concolorous with remainder of hemelytron ( Fig. 2View FIGURE 2). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: flat in ventral view ( Fig. 2View FIGURE 2); eyes about 2/3 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 wedgeshaped. ABDOMEN: as in subgeneric description; stVI without process on posterior margin; subgenital plate weakly asymmetrical; process of subgenital plate needle-shaped ( Fig. 5AView FIGURE 5 A – L); 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 and sharp tip; lp as in subgeneric description, uniformly rounded in dorsal view ( Fig. 5AView FIGURE 5 A – L); rca flat and sickle-shaped with serrated ventral margin; lca small, about less than 1/4 length of rca, with hanging tubular process; vesica uniformly cylindrical and thin, forming a single coil; anophore forming asymmetrical tube with prominent dorsal fold.

Female: Unknown.

Distribution. Known from the northern region of Costa Rica, from the provinces of Alajuela and Heredia ( Fig. 7).

Etymology. Named for the needle-like process of the subgenital plate after the Latin “acutus” meaning sharpened.
