( Figs 2 , 5 and 7)

Schizoptera (Odontorhagus) decius McAtee and Malloch, 1925: 67 , 17 (orig. descr.).

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the elongate, ovoid body shape, flat head, the small, blunt, upward curving process of the subgenital plate (sVII), the robust and curving right paramere, and the pronged left conjunctival appendage.

Holotype: PANAMA: Canal Zone : Gatún, 9.31646 ° N 79.80035 ° W, 0 7 Apr 1911, E.A. Schwarz, 1Ƌ (00028604) ( USNM).

Re-description. Male: length: 1.22–1.27 mm; body ovoid. COLORATION: general coloration dark brown; fuscous patch covering more than 1/2 of wing membrane; Sc+C concolorous distrinctly lighter than remainder of hemelytron ( Fig. 2 ), pigmentation of corium slightly extending into cubital cell and anal region of membrane. SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: slightly rounded ventral view ( Fig. 2 ); eyes about 1/2 as wide as synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein slightly curving, anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI with large rounded process on posterior margin; subgenital plate weakly asymmetrical; process of subgenital plate blunt and rectangular, pointing apically ( Fig. 5G ); tVII rectangular; tVIII rectangular and distinctly sclerotized; length of tVIII about 1/2 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with a curving tapering stem and pointed tip; lp triangular in dorsal view; rca elongate and needle-shaped; lca about 1/4 length of rca, with two prong-like processes in dorsal view; vesica uniformly cylindrical and thin, forming almost two coils; anophore as in subgeneric description.

Female: Unknown.

Distribution. Known from three localities in southern Panama ( Fig. 7).
