Diagnosis.

Zanchisme mexicanus (Figs 102-104) is recognized by the two well-developed, sharp spines on the anterior lobe of the pronotum, the partially dull and partially shiny hemelytra, the black bristle-like dorsal setae, and the male genitalia.

Description.

Male (n = 5; holotype measurements in parentheses): Length to apex of membrane 3.20-3.62 mm (3.17 mm); width 0.98-1.17 mm (0.96 mm). Head: Width 0.74-0.77 mm (0.69 mm), interocular width 0.30-0.32 mm (0.32 mm). Labium: Length 0.96-0.98 mm (0.88 mm). Antenna: Segment I, length 0.21-0.24 mm (0.21 mm); II, 0.64-0.67 mm (0.52 mm); III, 0.40-0.42 mm (0.32 mm); IV, 0.35-0.40 mm (0.32 mm). Pronotum: Length 0.80-0.85 mm (0.75 mm), basal width of posterior lobe 0.91-1.07 mm (0.93 mm), width of anterior lobe 0.48-0.53 mm (0.48 mm), width of constriction 0.34-0.38 mm (0.34 mm).

Coloration: Head: Reddish brown to dark brown. Antenna: Pale yellowish brown, with a narrow red line along ventral surface and short, apical red line on dorsal surface; segment II yellowish brown to brown, with a short, narrow red to brown line dorsally at base; segments III and IV dark brown. Pronotum: Yellowish brown, dark brown, to dark reddish brown, anterior lobe sometimes paler than posterior lobe. Mesoscutum: Brown to dark reddish brown. Scutellum: Brown to dark reddish brown. Hemelytron: Corium inside radial vein and clavus yellowish brown; area outside radial vein and cuneus brown to dark brown; membrane dark smoky brown, paler or whitish inside areoles. Ventral surface: Thoracic area brown to reddish brown; abdomen dark reddish brown to fuscous. Ostiolar evaporative area: Largely white, with raised central area of auricle red. Legs: Fore coxa brown, middle and hind coxae pale or whitish; fore femur dark brown, middle and hind femora dark brown on apical half, pale or yellowish brown basally; tibiae dark brown, pale or yellow at apices; tarsi and claws pale yellow.

Structure, texture, and vestiture: Head: Shiny, impunctate. Labium: Extending to middle of mesosternum. Pronotum: Bilobed, narrowed anterior lobe with two, long, sharply pointed tubercles, one on either side, middle smooth, shiny; posterior lobe strongly convex; shiny, impunctate, polished; with scattered, short, recumbent, simple setae. Mesoscutum: Shiny, impunctate, with a few short, simple setae. Scutellum: Dull, narrowly shiny along base, impunctate; with a broad band of silvery scale-like setae across middle. Hemelytron: Dull on clavus and corium inside radial vein, shiny on cuneus and corium outside radial vein; with wide band of silvery, scale-like setae across base of clavus and a wider patch of less dense silvery scale-like setae across middle of corium and apical third of clavus, intermixed on dull surface, with evenly placed, long, erect, bristle-like setae. Ventral surface: Shiny; abdomen with scattered and irregular rows of short, recumbent, simple setae.

Male genitalia: Left paramere (Fig. 301) with an elongate, beak-like process apically, and a smaller beak-like process at middle facing opposite direction. Right paramere (Fig. 303) with a slender main stem and one marginally crenulate lateral arm. Phallotheca (Fig. 302) evenly slender, with a slender, curved apical hook.

Female (n = 3): Length to apex of membrane 2.94-3.17 mm, width 1.02-1.04 mm. Head: Width 0.70-0.75 mm, interocular width 0.42-0.43 mm. Labium: Length 0.83-1.01 mm. Antenna: Segment I, length 0.19-0.24 mm; II, 0.50-0.59 mm; III, 0.32-0.37 mm; IV, 0.27-0.35 mm. Pronotum: Length 0.70-0.75 mm, basal width of posterior lobe 0.84-0.86 mm, width of anterior lobe 0.48-0.50 mm, width of constriction 0.32-0.37 mm.
