Cyrtopeltocoris nudipronotum , new species

Figures 3 , 5 , 6 , table 1

DIAGNOSIS: Recognized by the distinctly convex pronotum and scutellum; pronotum glabrous and shining laterally and finely rugulose medially (fig. 3); white transverse fascia on hemelytron broad, more or less parallel sided (fig. 3); and endosoma greatly extending beyond secondary gonopore with subapical lateral membranous lobe (fig. 5). Most similar to C. albofasciatus , C. gracilentis , and C. huachucae in general appearance, but differing from all of them by its distinctive pronotal surface and by endosoma greatly extending beyond secondary gonopore; differing from from C. albofasciatus and C. gracilentis by the presence of short recumbent setae rather than long erect setae on hemelytron. Cyrtopeltocoris nudipronotum is similar to C. ajo in having the same pronotal surface texture and general dorsal color pattern but differs in the evenly rounded frons and clypeus and a much smaller, more slender right paramere, whereas C. ajo has a distinct notch at the base of the clypeus (similar to C. huachucae ) and the right paramere is large and broad.

DESCRIPTION: Male: Mean total length 3.92. Coloration (fig. 3): Head reddish brown; labium brown; pronotum dark brown, dark brown and blackish laterally, or dark orange and brownish black laterally; mesoscutum and scutellum dark brown; scent-gland auricle brown; clavus brown or brownish orange basally, sometimes slightly darker at margin of white medial part, white medially, brown apically; corium brown or dark brownish orange basally, white medially, brown apically; white band straight or just very slightly swollen medially (fig. 3); corium with roundish white spot at cuneal fracture not reaching inner margin; cuneus dark reddish brown; membrane fuscous; antennae brown with segment 1 yellowish brown, segment 4 sometimes reddish; venter reddish; mesepisternum reddish brown; coxae and trochanters ivory; femora and tibiae reddish brown; tarsi yellowish. Surface and vestiture (fig. 3): Head, scutellum, and clavus bearing long erect setae; pronotum and corium with recumbent setae; pronotum glabrous and polished laterally and finely rugulose and dull medially. Structure (fig. 3): Slender; pronotum distinctly swollen, campanulate (fig. 3); scutellum distinctly swollen; corium with lateral margin slightly convex basally at level of brown coloration; labium reaching metacoxae. genitalia (fig. 5): Endosoma coiled, slender, with a subapical, dentate, lateral membranous lobe; secondary gonopore strongly removed from apex of endosoma (fig. 5); phallotheca just slightly curved, with a widened lobelike apex; left paramere with anterior process stout, posterior process elongate and curved downward; right paramere short and widened basally.

ETYMOLOGY: Named for the glabrous lateral areas of the pronotum, from the Latin nudus, meaning “bare,” and pronotum.

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