( Figs. 1 View FIGURE 1 A–C, 2A–G)

Diagnosis: Distinguished by the following combination of characters: body bright yellowish brown; narrow dark markings in posterior part of corium ( Figs. 1 View FIGURE 1 A–C); rounded lateral margin and thick hypophysis of right paramere ( Fig. 2B View FIGURE 2 ); endosoma with five sclerites and one spicule, without sclerite VI; elongated sclerite I, elongated-oval sclerite II, sclerite III with projected apex, elongated-oval sclerite V with tooth like structure, thin scythe-shaped spicule ( Figs. 2 View FIGURE 2 C–D); broadly developed lateral lobe, reaching to lateral margin of interramal lobe, sharp medial apex of interramal lobe ( Figs. 2 View FIGURE 2 F–G).

Description: Male: Body oval, length 3.05. COLORATION: mostly yellowish brown. Head: pale brown dorsally, two-colored with reddish brown frons and entirely dark brown clypeus, mandibular plate and maxillary plate; antennae generally dark brown; first segment yellowish brown with dark stripe laterally; second segment entirely dark brown; third segment almost dark brown except for pale brown base; fourth segment entirely dark brown; clypeus, mandibular and maxillary plates entirely dark brown; labium almost reddish brown, base of first segment and apical part of fourth segment dark brown, others reddish brown. Thorax: pronotum entirely yellowish brown with reflection of dark coloration under pronotum; callus and anterior part of pronotum brown; pronotal collar brown; scutellum entirely blackish dark brown; hemelytra generally brownish orange; inner part of clavus dark brown with dark commissure, dark coloration connecting to scutellum; postero-lateral and postero-medial parts with dark markings; inner part of cuneus dark brown, apex of cuneus dark brown; legs almost brownish orange; femur with brownish rings subapically, tinged with red slightly; apex of tibia dark brown; third tarsal segment dark brown. Abdomen: entirely blackish dark brown, genital segment somewhat paler ventrally. SURFACE AND VESTITURE: as in generic description. STRUCTURE: Head: vertex width shorter than length of first antennal segment and longer than eye width in dorsal view; antennae cylindrical; first and second antennal segment thicker than others; second antennal segment slightly thicker gradually toward apex; apex of labium slightly exceeding apex of hind coxae; proportion of first to fourth labial segments 0.3:0.4:0.3:0.4. Thorax: pronotum trapezoid, posterior margin of pronotum angled convexly; scutellum equilateral; lateral margin of hemelytra rounded; cuneal fracture well developed; membrane with two cells; legs generally slender; hind femur somewhat thick; tibia slender; third tarsal segment longer than others. Abdomen: rounded, reaching to apex of cuneus. GENITALIA: left paramere with upwardly developed sensory lobe, apex of hypophysis sharp and curved medially ( Fig. 2A View FIGURE 2 ); right paramere rod-shaped, lateral margin slightly rounded, hypophysis somewhat thick, its apex sharp ( Fig. 2B View FIGURE 2 ); endosoma with one spicule and five sclerites, membranous parts reduced; sc I elongated with spinules; sc II elongated oval, flat; sc III broadly developed subapically, with sharp projection apically; sc IV long, its apex circular; sc V long, its apex elongated oval, with tooth like structure, scs long and thin ( Figs. 2 View FIGURE 2 C–D).

Female: Ovoid, length 3.38. COLORATION: as in male except for somewhat darker posterior part of inner corium. SURFACE AND VESTITURE: as in male. STRUCTURE: somewhat more rounded oval in overall shape than male. GENITALIA: sr elongated oval, closed to each other, its outer apex tapered ( Fig. 2E View FIGURE 2 ); llb positioned on irl, llb broadly developed, reaching to lateral margin of irl; irl largely developed, with projection medially, its apex somewhat narrow and sharp; ms elongated oval ( Figs. 2 View FIGURE 2 F–G).
