Description – Colouration. Body mostly dark brownish. Head. Vertex with extended dark brownish region exceeding base of clypeus. Apical half of clypeus, mandibular plates and antenniferous tubercles ochraceous. Eyes reddish, ocelli ochraceous. Antennal segment I ochraceous, infuscated ventrally; segment II–III fuscous, base of segment II and apex of segment III with ochraceous annulation basally; segment IV entirely ochraceous. Head ventrally ochraceous with dark fuscous “collar” at base. Labial segments ochraceous; segment I sometimes with irregular fuscous marking in basal half. Thorax. Pronotum dark brownish with small ochraceous spots of various extent at humeral angles. Scutellum uniformly dark brownish. Hemelytra semi­hyaline ochraceous with extended fuscous regions on clavus and corium. Costal margin and membrane margined with brown. Thoracic pleurites and sternites dark brownish; prothorax with ochraceous collar ventrolaterally; supracoxal lobes and orifice of metathoracic scent gland variably ochraceous or pale fuscous. Legs uniformly ochraceous. Abdomen. Abdominal segments dark brownish; connexiva marginated with ochraceous laterally; bulges of spiracles on segment V–VI ochraceous.

Structure – Body surface shiny without conspicuous pubescence. Head. Ocular sulcus slight, but complete. Width of head greater than basal width of pronotum (ratio: 1:0.92). Sparse, bristle like setae present above antenniferous tubercles. Ratio of antennal segments: 1:2.29:2:2. Antennal segments covered with sparse, decumbent setae. Ratio of labial segments: 1:0.73:0.93:1.33. Thorax. Pronotum trapezoidal; anterior edges more, posterior margins less curved. Disc of pronotum with deep, dense punctuation. Ratio of pronotum length to basal width: 1:1.55. Scutellum shiny with dense, strong punctuation except elevated, trifurcate median carina. Length and width of scutellum subequal (ratio: 1:0.96). Hemelytron macropterous with well-developed membrane. Incomplete row of punctures at corial margin of clavus. A row of punctures at corium near claval margin splits into two diverging rows at 2/3 of length. Radius punctate at almost full length; strong punctuation in apical third of R­M region. Thoracic pleurites with strong, dense punctation. Abdomen. Connexiva with sparse decumbent pubescence; genital capsule with few stronger setae.

Measurements [holotype (minimum and maximum of studied specimens)] – Total body length: 3.90 (4.00–4.53); head length: 0.50 (0.50–0.53); head width: 1.53 (1.57–1.70); distance of ocelli: 0.47 (0.47–0.50); antennal segments: 0.20­0.51­0.46­0.46 (0.23­0.54­0.47­ 0.47 – 0.25­0.55­0.48­0.48); labial segments: 0.48­0.34­0.45­0.64 (0.50­0.36­0.56­0.67 – 0.53­ 0.40­0.58­0.70); pronotum length: 0.93 (0.93–0.97); pronotum width: 1.37 (1.47–1.53); scutellum length: 0.77 (0.83–0.87); scutellum width: 0.73 (0.87–0.90).

Distribution – Every specimen known to the author is originated from the mountain rainforests near Wau and Port Moresby, eastern New Guinea.

Etymology – The species is named as a tribute to the work of the excellent Hungarian heteropterist, Előd Kondorosy, professor at University of Pannonia.
