(Figs. 1 A–B, 2A–E, 3)
Diagnosis. Differs from other Palaearctic Graptopeltus species by body dark brown; pronotal margin dark and yellowish pale brown densely covered with dark punctures; margin of hemelytra with dense dark punctures; corium with small dark spot in middle part (Figs. 1 A–B, 3).
Description. Male (Fig. 1 A): Body broadly oval. COLORATION: Mostly mottled dark brown with distinct dark punctures. Head: dark brown; compound eyes fuscous; ocelli dark brown; antennae almost dark brown, apex of each segment pale brown; clypeus dark brown; rostrum dark brown. Thorax: pronotum dark brown; anterior lobe dark brown; lateral margin dark brown with mottled pale brown; posterior lobe mottled dark brown; scutellum dark brown; with pale spots at middle; ostiolar peritreme dark brown; hemelytra mottled brown; 2/3 anterior part of lateral margin of hemelytra yellowish pale brown with densely dark punctures; corium with dark brown marking; membrane grayish dark brown, veins dark brown; legs dark brown except for pale apex of femur; fore femur dark brown with reddish brown stripe; tarsus dark brown, base reddish brown. Abdomen: entirely dark brown. SURFACE AND VESTITURE: Body with distinct punctures, glossy; frons with long pubescence; clypeus with dense pubescence; antennae with short and thin pubescence generally, first antennal segment with suberect setae; legs with dense pubescences and longer spines; claw with long three pubescences. STRUCTURE: Head: projected frontally; compound eyes touching anterior margin of pronotum; vertex width about two times as long as first antennal segment; clypeus projected dorsally; first antennal segment distinctly thicker than others, second antennal segment 3 times as long as first antennal segment; rostrum reaching to midcoxae. Thorax: Pronotum trapezoidal with rounded lateral margin; scutellum equilateral; lateral margin of hemelytra rounded; legs generally thick; fore femur thicker than others with one process lateroventrally; mid and hind tibia with spines. Abdomen: rounded, reaching to apex of hemelytra. GENITALIA: Pygophore pentagonal dorsally, posterior margin convex laterally (Figs. 2 A–B); paramere tapered, apex round, with a process at middle, with sparse setae (Fig. 2 C); aedeagus membranous with distinct two long lobes and small lobes (Fig. 2 D).
Female (Fig. 1 B): COLORATION: A s in male. SURFACE AND VESTITURE: As in male. STRUCTURE: Somewhat more rounded oval in overall shape than male. GENITALIA: Spermatheca long, especially much thicker in apical part, with distinctly circular apex connecting to trumpet-shaped structure (Fig. 2 E).
