Schizoptera (Odontorhagus) piscicaudata , n. sp.

( Figs 3 , 6 and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the rounded head, the weakly asymmetrical subgenital plate, the “fishtail” shaped process of the subgenital plate, and the tapering right conjunctival appendage with a serrated tip.

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. 3 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: slightly rounded in ventral view ( Fig. 3 ); eyes about 1/3 as wide as synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein straight; anterior membranal cell triangular. ABDOMEN: as in subgeneric description; stVI without process on posterior margin; subgenital plate weakly asymmetrical; process of subgenital plate fishtail shaped ( Fig. 6O ); tVII rectangular; tVIII weakly rectangular and sclerotized; length of tVIII about 1/2 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with a hook-like stem; lp as in subgeneric description, with two triangular dorsal processes; rca tapering with a serrated tip; lca small, about 1/4 length of rca, with blunt and fin-shaped processes juxtaposed in a twist ( Fig. 6O ); uniformly thin with a needlelike tip; anophore as in subgeneric description.

Female: Unknown.

Distribution. Known from a single locality in the northern Costa Rican province of Heredia and a single locality in the Canal Zone in Panama ( Fig. 7).

Etymology. Derived from the Latin “piscis” meaning fish and “caudatus” meaning tailed.
