Cyrtopeltocoris gracilentis Knight, 1930 (original description).

Cyrtopeltocoris oklahomae Knight, 1968: 162 (original description). New synonym.

DIAGNOSIS: Recognized by the long erect setae covering the entire dorsum, the wide vertex, the conical scutellum more strongly elevated than in any other species except C. cubanus and C. illini (figs. 1, 2), the continuous transverse fascia across corium and clavus, the basal ivory spot on the corium along the basal margin of the cuneus (fig. 2) that extends to the inner corial margin, the white ostiolar evaporative area, and the endosoma elongated beyond the secondary gonopore and with a rounded apex (fig. 4). Similar to C. albofasciatus in appearance, coloration, and structure of endosoma, but differs in having long setae on dorsum occurring on pronotum as well as scutellum and hemelytra, the scutellum more strongly elevated than in that species, and endosoma with a distinctive sclerotized bar distad of the secondary gonopore. Coloration and the long erect dorsal vestiture similar to those of C. mexicanus (fig. 3), but scutellum much more strongly elevated and transverse hemelytral fascia and white mark anterior to cuneus distinctly narrower.

REDESCRIPTION: Male: Mean total length 3.67. Coloration (fig. 2): Head reddish brown; labium yellowish brown; pronotum reddish brown; mesoscutum and scutellum reddish brown; scent-gland auricle white; clavus reddish brown basally, white medially and brown apically; corium and embolium brown apically and basally, white medially forming a continuous, unbroken fascia with clavus; medial part of transverse white band on corium more slender than laterally (fig. 2); corium with a white mark along basal margin of cuneus, extending nearly to inner margin of corium (fig. 2); cuneus reddish; membrane fuscous; antennae yellowish brown; venter brown; mesepisternum orange brown; procoxae reddish apically, yellowish basally, trochanter of front leg reddish, mesocoxa white with a brown spot basally, and metacoxae white, trochanters white; femora reddish brown basally, yellow apically; tibiae reddish brown, paler apically; tarsi yellowish. Surface and vestiture: Vertex bearing recumbent and erect simple setae; pronotum bearing recumbent setae; scutellum and hemelytron with distinct erect setae; frons and calli distinctly granular. Structure (fig. 2): Slender; pronotum trapezoidal, tumid; scutellum distinctly swollen or conical (fig. 2); corium with lateral margin slightly convex basally at level of brown coloration; labium reaching metacoxa. genitalia (fig. 4): Endosoma coiled, slender, ending in rounded membranous apex with minute serrations (fig. 4); phallotheca curved, ending in a rounded apex (fig. 4); left paramere strongly elevated, anterior process short and stout; posterior process elongate and distinctly curved downward; right paramere roundish, apex short, acuminate (fig. 4).

DISTRIBUTION (fig.6): This species is widely distributed in the eastern United States. Its distribution shows some overlap with that of C. illini , but otherwise appears to be the only species occurring in the area.

DISCUSSION: The holotype of C. oklahomae Knight , deposited in the USNM, is badly damaged. All body parts except the right hemelytron are missing. The synonymy of C. oklahomae is based on a dissected specimen from Claremore, Oklahoma, the type locality for this nominal taxon.

The holotype of C. gracilentis (fig. 2) is elongate and somewhat delicate in appearance. It is lighter reddish brown, in contrast to the dark reddish-brown or castaneous coloration of most known specimens of this species. Several specimens from Gainesville, Florida, are all more strongly castaneous and slightly more robust than the holotype from Alabama. In the westernmost part of the range in Oklahoma the more elevated scutellum, the white ostiolar auricle, and the complete white corial mark adjacent to the cuneus will separate C. gracilentis from C. albofasciatus (fig. 1), the latter having a less strongly elevated scutellum, a red ostiolar auricle, and the apical corial mark does not reach mesially to the membrane.
