Sericophanes rubripes Knight, 1968: 161 (original description).

Sericophanes tumidifrons Knight, 1968: 160 (original description). New synonym.

DIAGNOSIS: Recognized by the somewhat robust body form, long erect setae on dorsum, generally dull appearance of hemelytron compared with the shining, campanulate pronotum, the relatively short antennal segment I, the broad vertex, the conspicuously swollen frons (fig. 3), and the robust, tightly coiled endosoma with a triangular subapical flap distal to the secondary gonopore (fig. 5). Similar to C. mexicanus in distribution, reddish coloration, and erect setae on dorsum, but C. mexicanus distinguished by the shorter first antennal segment, the nearly straight-sided posterior lobe of pronotum, the more elongate body form (fig. 3), and the slender, rather weakly coiled endosoma lacking the subapical triangular flap (fig. 5).

REDESCRIPTION: Male: Mean total length 4.15. Coloration (fig. 3): Head orange brown; labial segment 1 red, segment 2 pale, segments 3 and 4 reddish; pronotum dark orange to brown; mesoscutum and scutellum brownish orange; scent-gland auricle whitish; clavus hemelytra with a broad, weakly defined, white to transparent fascia at level near the apex of the scutellum, extending anteriorly on exocorium, and with a large white quadrate marking along cuneal fracture; clavus orange basally, corium and clavus broadly brown on posterior half (fig. 3); membrane pale translucent brown, cells weakly infuscate; antennae pale to orange; legs pale, femora tinged with red apically (fig. 3); venter reddish brown. Surface and vestiture (fig. 3): Dorsum shining, weakly rugulose; head, pronotum, and appendages bearing recumbent short setae; pronotum, mesoscutum, and scutellum in addition with simple erect setae and corium with long, erect, pale setae (fig. 3). Structure (fig. 3): Relatively stout bodied, costal margin of corium moderately sinuous; pronotum weakly campanulate; scutellum more or less flat; labium reaching abdominal segment 3. genitalia (fig. 5): Endosoma heavy bodied, with a single tight coil; secondary gonopore distinctly removed from apex, apical portion flattened with a dentate triangular projection (flap); phallotheca and parameres as in generic description.

Female: Unknown.

DISTRIBUTION (fig. 6): Known from Arizona, southern California, and southern Nevada.

DISCUSSION: After examination of the holotype, and dissection of the male genitalia of material that is clearly conspecific, we transfer Sericophanes rubripes Knight to Cyrtopeltocoris .

The holotype of Sericophanes tumidifrons Knight has no legs or antennae. Nonetheless, based on the shape of the head in lateral view, the golden coloration of the head and pronotum, and the weakly elevated scutellum, we transfer S. tumidifrons to Cyrtopeltocoris and treat it as a junior synonym of C. rubripes (Knight) . The transverse fascia is narrowed medially in the type of S. tumidifrons whereas it is of more or less equal width across the breadth of the hemelytra in most specimens we assign to S. rubripes . Based on page priority, S. tumidifrons would be the senior synonym, but the holotype of S. rubripes is in better shape and the identity of the species therefore more easily established. For these reasons, we treat S. rubripes as the valid name under the rule of first reviser.

In addition, we have found a brachypterous male that we initially associated with C. rubripes , based its reddish coloration and distribution, but examination of the male genitalia indicates it apparently represents a new species. Insufficient material precludes describing it at this time.
