Diagnosis.
Distinguished among species of
Schizoptera
(
Odontorhagus
)
by the broadly ovoid body shape, the dark brown coloration, the rounded head, the small, tooth-like process on the posterior margin of sVI, the single, jagged, hitch-hikers thumb-like process of the subgenital plate, the needle-shaped right conjunctival appendage, and the bifurcating left conjunctival appendage.

Description.
Male
: length:
1.43–1.49 mm
; body broadly ovoid.
COLORATION:
general coloration dark brown; fuscous patch covering less than 1/2 of wing membrane; Sc+C concolorous with remainder of hemelytra (
Fig. 2
).
SURFACE AND VESTITURE:
as in subgeneric description.
STRUCTURE:
HEAD: distinctly 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 slightly curving anteriorly toward wing margin, anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI with a small, tooth-like process on posterior margin; subgenital plate weakly asymmetrical, with jagged margins a single lateral process; process of subgenital plate jagged, and shaped like a hitch-hiker’s thumb (
Fig. 5D
); 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 pointed tip; lp as in subgeneric description, with a funnel-shaped dorsal process (
Fig. 5D
); rca needle-shaped; lca small, about less than 1/4 length of rca, with with a rounded base and two sharp bifurcations; vesica uniformly cylindrical and thin, forming a single coil; anophore as in subgeneric description.
Female
: length:
1.47–1.49 mm
; general habitus as in males.

Known from two localities in northern
