Cyrtopeltocoris mexicanus Carvalho and Costa, 1995: 230 (original description).

DIAGNOSIS: Recognized by the slender elongate appearance (fig. 3), general light brownish coloration, broad, white medial hemelytral fascia, large white quadrate marking on corium anterior to cuneal fracture, the long antennal segment I, the long erect setae on the dorsum, and the endosoma with a distinct bifurcate apex (fig. 3). Most similar to C. gracilentis and C. rubripes in presence of long erect setae on entire dorsum, but distinguished from both by the relatively long antennal segment I, the much broader hemelytral fascia, and the quadrate white area anterior to cuneus; C. gracilentis with a more strongly produced scutellum, narrower hemelytral fascia, and nonoverlapping distribution and C. rubripes with a shorter, more compact, reddish body and more strongly diffuse white areas on the hemelyra.

REDESCRIPTION: Male: Mean total length 4.74. Coloration (fig. 3): Head orange brown; labium yellow with first segment orange; pronotum dark brownish orange to reddish brown; mesoscutum and scutellum brownish orange; scent-gland auricle whitish; clavus brownish orange basally, white medially, brown apically; corium orange basally, white medially, brown apically; apex of corium bordering cuneus with a large quadrate white spot; cuneus reddish brown; membrane fuscous; antennal segment 1 light brown, second light brown, red apically, third reddish on apical half, fourth reddish brown; venter brown; mesepisternum red; coxae ivory; trochanters and femora light brownish orange tinged with red; tibia bright red basally, paler apically; tarsi yellowish orange. Surface and vestiture (fig. 2): Dorsum with long erect setae. Structure (fig. 3): Elongate and slender; pronotum slightly trapeziform; scutellum weakly convex; labium reaching abdominal segment 3. genitalia (fig. 5): Endosoma coiled, slender, apex membranous, bifurcate, only moderately extending beyond secondary gonopore (fig. 5); phallotheca strongly curved, round apically; left paramere with anterior process strong, posterior process elongate and almost straight; right paramere elongate.

DISTRIBUTION (fig. 6): Known from southern California and Baja California, Mexico.

DISCUSSION: The holotype of C. mexicanus , described from “B. Calif. [Baixa Califó, Mexico], 2 mi. NE of Rosario, 7.XII.1958, H.B. Leech col.,” is lost. It was not returned to the California Academy of Sciences as indicated in the original description and apparently was destroyed in the 2018 Museu Nacional (Rio de Janeiro) fire. Based on the original description, which included an illustration of the adult male and figures of male genitalia, we are able to associate this species with the series of specimens listed below. To ensure nomenclatural stability, we are selecting the male listed below as the neotype.
