Schizoptera (Odontorhagus) brevis View in CoL n. sp.

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

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the relatively small size, the light brown coloration, the small finger-like process of the subgenital plate, the large, curving and serrated right conjunctival appendage and the slender, needle-like left conjunctival appendage.

Description. Male: length: 1.15–1.19 mm; body ovoid. COLORATION: general coloration light brown; fuscous patch absent; Sc+C distinctly lighter than remainder of hemelytra ( Fig. 2 View FIGURE 2 ), pigmentation of corium slightly extending into cubital cell and anal region of membrane; SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: flat in ventral view ( Fig. 2 View FIGURE 2 ); eyes about 1/2 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, tab-like process on posterior margin; subgenital plate distinctly asymmetrical, with left side reduced ( Fig. 5E View FIGURE 5 A – L ); process of subgenital plate smooth, and finger-like; tVII weakly trapezoidal, almost hemispherical; tVIII weakly trapezoidal and distinctly sclerotized; length of tVIII about 1/2 length of tVII. GENITALIA: py as in subgeneric description; rp small, obscured by rca; lp as in subgeneric description, with a bilobed dorsal process ( Fig. 5E View FIGURE 5 A – L ); rca large, robust and distinctly serrated at apex and wrapping around anophore; lca small and thin, about 1/4 length of rca, with a tapering, needle-like apex; vesica short and tapering, forming a single coil; anophore as in subgeneric description.

Female: 1.19 mm; general habitus as in male, with head slightly broader than in males.

Distribution. Known from three localities in Panama, the Canal Zone, the provinces of Bocas del Toro and Colon on the Caribbean coast ( Fig. 7).

Etymology. Named for the small body size, and the small process of the subgenital plate after the Latin “ brevis ” meaning small or short.
