Diagnosis.

Zanchisme dromedarius (Figs 95-97) is distinguished by the three short tubercles across the anterior lobe of the pronotum, the uniformly shiny hemelytra, the golden scale-like setae on basal half of the corium, and apically pale antennal segment II. This is the only species of the genus with three tubercles on the anterior pronotal lobe.

Description.

Male (n = 1): Length to apex of membrane 3.20 mm, width 1.02 mm. Head: Width 0.82 mm, interocular width 0.29 mm. Labium: Length 0.93 mm. Antenna: Segment I, length 0.22 mm; II, 0.62 mm; III, 0.40 mm; IV, 0.37 mm. Pronotum: Length 0.83 mm, basal width 0.85 mm, anterior width 0.45 mm, width at constriction 0.30 mm.

Coloration: Overall yellowish brown. Head: Yellowish brown; eyes black. Pronotum: Anterior lobe yellowish brown; posterior lobe yellowish brown to dark brown. Mesoscutum: Dark brown. Scutellum: Dark brown. Hemelytron: Yellowish brown to slightly darker brown at base of corium and on cuneus; membrane smoky brown, paler at base and along apical cuneal margin. Ventral surface: Brown to reddish brown. Ostiolar evaporative area: Reddish brown. Legs: Femora reddish brown, basal fourth of hind femur pale; tibiae reddish brown, apical thirds of middle and hind femora becoming pale yellowish brown; tarsi and claws pale yellowish brown.

Structure, texture, and vestiture: Head: Impunctate; with scattered semierect simple setae. Labium: Extending to middle of mesosternum just before middle coxae. Pronotum: Bilobed, narrowed anterior lobe with three, short tubercles, the middle one most prominent; posterior lobe strongly convex; anterior lobe impunctate; posterior lobe very finely punctate, appearing impunctate in certain light; with only scattered semierect simple setae. Scutellum: Finely transversely rugose. Hemelytron: Shiny, finely punctate, punctures heavier across pubescent patches and on cuneus; with two loose bands of silvery, scale-like setae, one across base of clavus and through middle of scutellum and one across middle of corium and onto adjacent clavus, intermixed on clavus and apical margin of corium with long, erect and semierect pale, nearly bristle-like setae and more generally scattered, shorter, pale simple setae. Ventral surface: Shiny.

Male genitalia: Left paramere (Fig. 292) with slender beak-like apex and a quadrate process at middle. Right paramere (Fig. 294) with main stem and primary arm forming a shallow C-shape, and with one accessory spine behind arm. Phallotheca (Fig. 293) with a relatively stout, right-curving apical process and a more narrow, left-curving process on opposite side.

Female (n = 1): Length to apex of membrane 2.98 mm, width 1.06 mm. Head: Width 0.78 mm, interocular width 0.40 mm. Labium: Length 0.93 mm, extending to middle of mesosternum. Antenna: Segment I, length 0.24 mm; II, 0.56 mm; III, 0.40 mm; IV, 0.38 mm. Pronotum: Length 0.80 mm, basal width 0.83 mm, anterior width 0.48 mm, width at constriction 0.27 mm.

Similar to male in overall shape and development of tubercles on anterior pronotal lobe, but slightly shorter and stouter, posterior pronotal lobe in lateral view more compressed from front to back, and hemelytral membrane slightly less elongate.
