( Figs 2 , 5 and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the large body size, the dark brown coloration, the distinct, asymmetrical subgenital plate with a large, irregular incision and two processes, the elongate, club-shaped anterior process of the subgenital plate, the jagged tab-like posterior process of the subgenital plate, the curving and distinctly sclerotized left process of the pygophore, and the serrated dorsal surface of the anophore.

Holotype: PANAMA: Panama: Cerro Campana , 8.68333°N 79.91667°W, 13 Feb 1959, Henry S. Dybas, 1Ƌ (00090825) ( FMNH) (microscopic slide mount) . PARATYPE: PANAMA: San Blas : 2 km N. Nusagandi, 9.35806 ° N 78.97833 ° W, 400 m, 14 Jan 2001, M. Yoder & J. B. Woolley, 1Ƌ (00093436) ( TAMU) .

Description. Male: length: 1.51–1.53 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. 2 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: slightly rounded in ventral view ( Fig. 2 ); 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 distinctly asymmetrical, with a large, irregular incision; anterior process of subgenital plate elongate, club shaped and curving ( Fig. 5J ); posterior process of subgenital plate jagged and tab-like; tVII weakly rectangular; tVIII weakly rectangular with a sharpened posterior margin on the left; length of tVIII about 3/4 length of tVII. GENITALIA: py as in subgeneric description, with an elongate, curving and sclerotized process on left margin; rp as in subgeneric description with a long, thick stem and fin-like tip; lp as in subgeneric description with two tubular dorsal processes; rca tapering with serrated margin; lca small, about 1/4 size of rca, and y-shaped ( Fig. 5J ); vesica short and tapering forming almost one coil; anophore forming an asymmetrical tube with a prominent dorsal fold and distinct serrations on dorsal surface ( Fig. 5J ).

Female: Unknown.

Distribution. Known from two localities in Panama: the Altos de Campana National Park in Panama province, and the San Blas region (now Guna Yala) on the northeast coast ( Fig. 7).

Etymology. Named for the bizarre subgenital plate morphology after the Latin “enigmaticus” meaning mysterious or puzzling.
