Diagnosis.

This species (Figs 100, 101) is distinguished by the two short tubercles on either side of the anterior lobe of the pronotum, the dull hemelytron with only the costal (emboliar) margin and cuneus shiny or polished, and the male genitalia.

Description.

Male (n = 5): Length to apex of membrane 3.10-3.78 mm, width 0.90-1.02 mm. Head: Width 0.70-0.75 mm, interocular width 0.18-0.21 mm. Labium: Length 0.98-1.10 mm. Antenna: Segment I, length 0.21-0.24 mm; II, 0.77-0.83 mm; III, 0.35-0.45 mm; IV, 0.37-0.49 mm. Pronotum: Length 0.72-0.80 mm, basal width of posterior lobe 0.86-0.91 mm, width of anterior lobe 0.34-0.35 mm, width of constriction 0.30-0.35 mm.

Coloration: Head: Yellowish brown to dark brown; eyes silvery, tinged with red. Antenna: Segment I pale yellow, with a narrow red (sometimes brownish) line on ventral surface and a short line on apical half of dorsal surface; segment II yellowish brown, apex more whitish, dorsal surface at base dark brown; segment III brown, apex more whitish; segment IV uniformly brown. Pronotum: Posterior lobe reddish brown to dark brown; anterior lobe yellowish brown to dark brown. Mesoscutum: Yellowish brown. Scutellum: Dark brown, with apex yellowish. Hemelytron: Yellowish brown to brown; costal margin (embolium) and cuneus reddish brown to dark brown; membrane dark brown, pale within areoles. Ventral surface: Thoracic area yellowish brown; abdomen yellowish brown, becoming darker brown distally toward genital capsule. Ostiolar evaporative area: White, central knob slightly embrowned. Legs: Fore coxae brown, middle and hind coxae white; fore and middle femora yellowish brown, darker dorsally, hind femur dark brown, pale at base and extreme apex; tibiae brown to reddish brown, pale on apical one third to one fourth; tarsi and claws yellowish.

Structure, texture, and vestiture: Head: Shiny, impunctate; interocular area smooth, frons becoming transversely rugose. Labium: Extending to middle of mesosternum, not quite reaching bases of middle coxae. Pronotum: Bilobed, narrowed anterior lobe with two, short, blunt tubercles, one on either side, middle smooth, shiny; posterior lobe strongly convex, polished, impunctate; anterior lobe shiny, alutaceous; with only sparsely scattered, recumbent, simple setae. Mesoscutum: Shiny, impunctate. Scutellum: Impunctate, weakly rugose; with four or five long, erect, setae. Hemelytra: Dull over most of corium and clavus, polished along costal margin (embolium) and cuneus; clavus with three patches of silvery scale-like setae, longest one across base, one at middle, and a small one on apex; corium with two patches of silvery scale-like setae, larger one at middle and smaller one more basal; intermixed with sparsely placed, long, erect, dark brown, bristle-like setae. Ventral surface: Shiny; abdomen with short, semierect, simple setae.

Male genitalia: Left paramere (Fig. 295) with a beak-like apical process and a short, slender, apically rounded process at middle. Right paramere (Fig. 297) with a slender main stem and one long, curved, marginally crenulate, lateral arm. Phallotheca (Fig. 296) evenly slender, with a slender, curved apical hook.

Female (n = 2): Length to apex of membrane 2.98-3.14 mm, width 0.90-0.91 mm. Head: Width 0.66-0.67 mm, interocular width 0.30-0.32 mm. Labium: Length 0.98-0.99 mm, extending slightly past middle of mesosternum. Antenna: Segment I, length 0.19-0.20 mm; II, 0.56-0.59 mm; III, 00.29-0.35 mm; IV, 0.35 (missing) mm. Pronotum: Length 0.64-0.69 mm, basal width of posterior lobe 0.78-0.80 mm, width of anterior lobe 0.32-0.34 mm, width of constriction 0.30-0.32 mm. Similar to male in coloration and general appearance, with head more rounded and the interocular area proportionately wider.

Host.

Unknown.

Distribution.

Known only from Jamaica.

Discussion.

Maldonado (1966) noted the association of this species with an ant ( Crematogaste r sp.) in St. Catherine Parish, Jamaica, and reported it from Ipomoea fistulosa Mart DC ex Choisy [ Convolvulaceae ] in Kingston.
