(Figs 1–3)
Diagnosis. Distinguished from other known congeners by the following combination of characters: head distinctly more inflated, somewhat flattened, and triangular in lateral view (Fig. 2A, B); scutellum relatively widely darkened anteriorly, with defined dark spots at apex; mesepimeron deeply punctate; scent efferent system with wide and rather square-shaped evaporative area; and femur yellowish-brown, without dark annulations.
Description. Female. Body elongated-ellipsoidal, length 3.84 mm (Figs 1A, B). Coloration. Shades of brown with places ivory tinged (Figs 1A, 2A). Head: mostly chestnut brown; vertex below ocelli and area along caudal margins of compound eyes pale brown (Fig. 1C); first antennae segment yellow-brown, second segment brown except for pale base, third and fourth segments ivory (Figs 1A, 2A); labium pale yellow, apical part of fourth segment brown. Thorax: pronotum mostly brown, anterior part and lateral spots ivory, lateral margin with narrow semitransparent extension, pronotal collar brown; scutellum ivory except for brown base; thoracic pleura chestnut brown; ostiolar peritreme ivory, evaporative area pale brown; hemelytra generally brown, exocorium pale, semitransparent, cuneus pale, membrane brown; legs yellowish-brown (Figs 1A, 2A). Abdomen: pale brown. Surface and Vestiture. Body weakly punctate, with uniformly distributed, silky reclining pubescence (Figs 1A, B, 2A, B); head impunctate, frons with row of setae along eye edges and scattered setae over remaining surface, posterior margin with long, reclining setae (Fig. 2C); antennae with erect setae; pronotal collar with row of setae; pronotum shiny, shallowly punctate, covered with fine setae, calli impunctate, shiny; mesoscutum almost impunctate and glabrous; scutellum shiny, sparsely punctate, covered with fine setae, sparse in apical part (Fig. 1A, B); thoracic pleura except pro-episternum deeply, unevenly punctate, and covered in places with scattered setae (Fig. 2A, B); hemelytra shallowly and densely punctate, covered with dense, brown, adherent, setae; legs with short, adherent, pale-brown setae; abdomen covered with pale-brown setae (Fig. 1A, 2A). Structure. Head: hemispherical, hypognathous, with width almost equal to height across eyes; compound eyes large, contiguous to each other, not strongly projected dorsally, more than 1/2 head height; vertex narrow; ocelli small, close together, touching compound eyes; vertex on same level as compound eye, slightly protruding dorsally relative to pronotal collar, not reaching highest point of pronotum (Fig. 2A, B); fovea antennalis positioned directly under compound eyes; frontal-clypeal part broad, (Figs 1C, D, 2C); first segment almost same length as fourth segment, as thick as distal part of second segment; second segment longest, longer than combination of third and fourth segment, distal part wider than basal; third segment longer than fourth, as thick as fourth (Figs 2A, B); labium long, fourth segment narrow, third and fourth segment partially fused (Fig. 2E). Thorax: pronotum trapeziform; pronotal collar thin; calli slightly marked, disc relatively flat, lateral margin carinate, posterior margin weakly sinuate, posterior angles weakly angled; mesoscutum short; scutellum flat; (Figs 1A, B, 2A, B); evaporatory area triangular; ostiolar peritreme inflated (Fig. 2B); hemelytron protruding beyond the abdomen, lateral margin slightly rounded; clavus broad; cuneus broad, inner margin straight; membrane with two cells; tarsus two-segmented; claw with a subapical tooth (Fig. 2D). Abdomen: elongate, not reaching the apex of cuneus. Genitalia: as in Fig. 3; bursa copulatrix simple, membranous, with two pairs basal sclerites of 8th gonapophyses; sclerotized rings obsolete; ovipositor elongate; apical part of gonapophysis 8 relatively smooth, slightly sharpened.
