Kohnometopus yasunagai Taszakowski, Kim & Masłowski sp. nov.

( Figs 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 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 View FIGURE 2 ); 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 View FIGURE 1 ). Coloration. Shades of brown with places ivory tinged ( Figs 1A View FIGURE 1 , 2A View FIGURE 2 ). Head: mostly chestnut brown; vertex below ocelli and area along caudal margins of compound eyes pale brown ( Fig. 1C View FIGURE 1 ); first antennae segment yellow-brown, second segment brown except for pale base, third and fourth segments ivory ( Figs 1A View FIGURE 1 , 2A View FIGURE 2 ); 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 View FIGURE 1 , 2A View FIGURE 2 ). Abdomen: pale brown. Surface and Vestiture. Body weakly punctate, with uniformly distributed, silky reclining pubescence ( Figs 1A, B View FIGURE 1 , 2A, B View FIGURE 2 ); head impunctate, frons with row of setae along eye edges and scattered setae over remaining surface, posterior margin with long, reclining setae ( Fig. 2C View FIGURE 2 ); 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 View FIGURE 1 ); thoracic pleura except pro-episternum deeply, unevenly punctate, and covered in places with scattered setae ( Fig. 2A, B View FIGURE 2 ); 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 View FIGURE 1 , 2A View FIGURE 2 ). 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 View FIGURE 2 ); fovea antennalis positioned directly under compound eyes; frontal-clypeal part broad, ( Figs 1C, D View FIGURE 1 , 2C View FIGURE 2 ); 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 View FIGURE 2 ); labium long, fourth segment narrow, third and fourth segment partially fused ( Fig. 2E View FIGURE 2 ). 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 View FIGURE 1 , 2A, B View FIGURE 2 ); evaporatory area triangular; ostiolar peritreme inflated ( Fig. 2B View FIGURE 2 ); 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 View FIGURE 2 ). Abdomen: elongate, not reaching the apex of cuneus. Genitalia: as in Fig. 3 View FIGURE 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.
