Male (n =10, plus holotype in parentheses) (Fig. 13): Length to apex of hemelytron 2.56–3.42 mm (2.83 mm), length to base of cuneus 1.90–2.25 mm (2.08 mm), width across hemelytra 0.80–0.99 mm (0.88 mm). Head: Length 0.30–0.34 mm (0.35 mm), width across eyes 0.61–0.67 mm (0.63 mm), interocular width 0.27–0.29 mm (0.29 mm). Labium: Length 1.20–1.38 mm (1.28 mm). Antenna: Segment I length 0.38–0.50 mm (0.38 mm), II 0.94–1.21 mm (1.10 mm), III 0.58–0.72 mm (0.66 mm), IV 0.40–0.59 mm (0.58 mm). Pronotum: Length 0.34–0.38 mm (0.35 mm), basal width 0.75–0.90 mm (0.78 mm). Coloration: Head: Uniformly fuscous to black, with a large, yellow, interocular spot near inner margin of each eye, spots nearly converging on some specimens; eyes fuscous to dark reddish brown. Labium: Pale yellow, with apical half of segment IV brown. Antenna: Segment I fuscous to black, with apical one quarter pale or yellowish; segment II pale yellowish brown, with a distinct fuscous band at base and sometimes with apex infuscated; segments III and IV black. Pronotum: Uniformly black. Mesoscutum: Uniformly black. Scutellum: Uniformly black. Hemelytron: Translucent, with a dark brown cloud or patch on apical half of cor- ium and inner apical half of clavus ranging from somewhat indistinct to a definite dark pattern (Figs 13, 14); membrane pale translucent brown. Ostiolar evaporative area: Dark brown to fuscous, with a yellow patch on posterior edge. Ventral surface: Thorax and abdomen uniformly fuscous to black. Legs: Coxae pale yellow, with basal thirds to halves dark brown; pro- and meso femora pale yellow, metafemur dark brown to fuscous, with basal third and apex pale yellow; tibiae pale, each with a fuscous base or “knee”; tarsi, and claws pale yellow. Structure, texture, and vestiture: Head: Shiny, impunctate; buccula relatively broad, tapering posteriorly, ending near level with middle of eye; set with scattered, semierect setae. Labium: Extending to metacoxe or base of abdomen; segment I extending beyond base of head onto xyphus to bases of procoxae. Antenna: Segment I sparsely set with recumbent setae and two erect, subapical bristlelike setae; segment II set with only very short, recumbent setae. Pronotum: Shiny, impunctate; anterior angles rounded; lateral margins weakly concave, widening at posterior angles; posterior margin weakly sinuate; calli weakly swollen; set with relatively long, recumbent setae. Mesoscutum: Weakly shining, impunctate, broadly exposed; set with a few scattered semierect setae. Scutellum: Shiny, impunctate; equilateral; set with scattered erect and semierect setae. Hemelytron: Macropterous, with cuneus and membrane fully developed, extending well beyond apex of abdomen; evenly set with relatively long, recumbent setae. Male genitalia: Left paramere (Fig. 128): Mitt-shaped; right arm long, broad, acute apically; left arm short, apically acute. Right paramere (Fig. 129): Endosoma (Fig. 130): S-shaped. Phallotheca (Fig. 131): Slender, apically acute. Female (n =5) (Fig. 14): Length to apex of hemelytron 2.82–3.52 mm mm, length to base of cuneus 2.05–2.50 mm, width across hemelytra 1.00–1.14 mm. Head: Length 0.30–0.35 mm, width across eyes 0.62–0.69 mm, interocular width 0.30–0.32 mm. Labium: Length 1.12–1.50 mm. Antenna: Segment I length 0.32–0.50 mm, II 0.85–1.17 mm, III 0.53–0.75 mm, IV 0.54–0.59 mm. Pronotum: Length 0.40–0.41 mm, basal width 0.91–0.99 mm. Similar to males in general appearance and coloration, differing primarily in the overall broader form. The one color exception is that the ventral area of the abdomen in many females is pale yellow, whereas in males the abdomen is always uniformly fuscous to black.
