Diagnosis.

This species (Figs 98, 99) is distinguished by the lack of tubercles on the anterior lobe of the pronotum, the uniformly shiny hemelytra, with a band of silvery, scale-like setae across the base of the clavus and corium and a loose patch of silvery scale-like setae through the middle of the corium and distal two thirds of the clavus, and the male genitalia, especially the left paramere (Fig. 298).

Description.

Male (n = 2; holotype measurements in parentheses): Length to apex of membrane 3.42 mm (3.30 mm), width 0.98 mm (0.99 mm). Head: Width 0.74 mm (0.77 mm), interocular width 0.18 mm (0.24 mm). Labium: Length 0.88 mm (0.94 mm). Antenna: Segment I, length 0.22 mm (0.24 mm); II, 0.66 mm (0.61 mm); III, 0.40 mm (0.40 mm); IV, 0.42 mm (0.35 mm). Pronotum: Length 0.74 mm (0.75 mm), basal width of posterior lobe 0.94 mm (0.91 mm), width of anterior lobe 0.35 mm (0.37 mm), width of constriction 0.34 mm (0.32 mm).

Coloration: Head: Brown to fuscous. Antenna: Segment I yellowish brown, with a narrow red line on dorsal and ventral surface; segment I brown, with a short dark brown line dorsally at base; segment III and IV dark brown. Pronotum: Dark brown, base of anterior lobe sometimes slightly paler brown. Mesoscutum: Brown. Scutellum brown, apex slightly paler. Hemelytron: Uniformly dark brown. Ventral surface: Thoracic segments dark brown; abdomen dark brown, glaucous stridulatory patch pale. Ostiolar evaporative area: Dark reddish brown. Legs: Fore coxae brown, middle and hind coxae whitish; fore femur dark brown, middle and hind femora dark brown with bases pale yellow or whitish; tibiae dark brown, with apices paler yellow; tarsi and claws yellowish.

Structure, texture, and vestiture: Head: Shiny, impunctate, frons weakly alutaceous; with scattered erect and semierect, simple setae. Labium: Extending to posterior margin of mesosternum, nearly to bases of middle coxae. Pronotum: Bilobed, narrowed anterior lobe lacking tubercles, anterior margin with a somewhat shallow, transverse ridge; posterior lobe strongly convex; shiny, polished, impunctate; with scattered, short, recumbent simple setae. Mesoscutum: Shiny, impunctate. Scutellum: Shiny, impunctate; with a brown band of silvery, scale-like setae through middle. Hemelytron: Uniformly shiny; with a band of silvery, scale-like setae across base of corium and clavus and a wide patch of less dense scale-like setae through apical two thirds of clavus and inner middle half of corium, sparsely intermixed with short, recumbent, simple setae and long, erect, bristle-like setae. Ventral surface: Shiny; abdomen with scattered and irregular rows of semierect, simple setae.

Male genitalia: Left paramere (Fig. 298) with an elongate beak-like process with opposite side extended into a long slender process; middle with a small, bilobed, wing-like process. Right paramere (Fig. 300) with a slender mainstem and one short lateral arm curved upward. Phallotheca (Fig. 299) stout, with a long, slender apical process and a shorter, more stout, recurved, subapical process.

Female (n = 2): Length to apex of membrane 2.94-3.10 mm, width 1.02-1.06 mm. Head: Width 0.70-0.74 mm, interocular width 0.32-0.34 mm. Labium: Length 0.98-1.02 mm, extending slightly past middle of mesosternum. Antenna: Segment I length 0.22-0.24 mm; II, 0.56 mm (one missing); III, 0.38 mm (one missing); IV, 0.42 mm (one missing). Pronotum: Length 0.69-0.70 mm, width of posterior lobe 0.85-0.91 mm, width of anterior lobe 0.30-0.32 mm, width of constriction 0.34-0.35 mm.

Host.

One specimen from Mexico was taken on Mimosa pigra L. [ Fabaceae ].

Distribution.

Previously known only from Oaxaca, Mexico. Guerrero is a new Mexican state record. Costa Rica and Honduras are new country records.
