( Fig 1E View FIGURE 1 , 3E View FIGURE 3 , 4 View FIGURE 4 .)

Holotype: ♀ ( SDEI): “ NEW GUINEA centr. / BALIEM TAL- 1700m / MARCH 1992 / leg. Jiří KOLIBAČ”.

Description.

Colouration. Body generally ochraceous with extended blackish decoration as follows. Head. Vertex with blackish spot extending from base of head to apex of clypeus. Eye stalks with irregular blackish markings posteriad. Antenniferous tubercle with irregular blackish spot dorsally. Antennomere I with an irregular elongate blackish spot laterally, antennomere II and III ochraceous, antennomere IV missing. Labiomere I with darkly infuscate spot basally, labiomere II dark ochraceous, labiomere III infuscate, apex of labiomere IV dark brownish. Thorax. Pronotum with anterior and lateral margins finely dark brownish or blackish, a blackish transversal band across pronotal callosities, dark brownish rounded spots at humeral angles and irregular dark brownish spots near and at posterior margin. Scutellum almost entirely black with median trifurcate carina and margins apically ochraceous. Clavus of hemelytron with dark brownish punctuation; corial margin and claval commissure narrowly dark brownish. Corium semi-hyaline with punctuation along veins dark brownish; punctures along Cu and adjoining part of margin of corium narrowly dark brownish. Thoracic pleurites and sternites black except ochraceous dorsal margins of pleurites, posterior margins of meso- and metapleurite, collar-like anterior margin of prosternite, supracoxal lobes and peritreme. Femora with sparse brownish maculae, tarsomeres infuscate. Abdomen. Abdominal dorsum entirely black. Abdominal sternites with a broad blackish band laterally, narrowing towards apex of abdomen; posterior edge of sternites VI–VII with dark brownish spots dorsally.

Structure. Head pentagonal, integument of vertex dull, impunctate. Eyes moderately stylate, eye stalks slightly projected, shiny. Ocular sulcus complete, distinct; ocelli situated near ocular sulcus, at basal part of vertex. Clypeus rounded, exceeding mandibular plates, medially constricted. Antenniferous tubercles well-developed, visible in dorsal view. Antennomeres covered with sparse, decumbent pubescence. Antennomere I shortest, antennomere II longest, antennomere IV missing. Ratio of antennomeres I–IV: 1: 2.74: 1.90: -. Mandibular and maxillary plates clearly separated; ventral margin of bucculae forming a U-shaped labial trough, labial trough almost reaching base of head. Labiomere I exceeding the anterior margin of prosternite, labiomere I–III subequal, labiomere IV shortest with apex reaching metacoxae. Ratio of labiomeres I–IV.: 1: 1.07: 1.19: 0.69. Thorax. Pronotum trapeziform with lateral margin finely carinate, slightly constricted medially; pronotum ratio: 1: 1.69. Integument with coarse, irregular punctuation except callosities, humeral angles and posterior margin. Scutellum subequilateral triangular; scutellum ratio: 1: 1.13; integument coarsely punctate except the elevated, trifurcate median carina. Clavus of hemelytron well developed, margins subparallel; claval commissure developed with a line of punctures at full length. Scutellar margin with 2–3 punctures basally, corial margin punctate at almost entire length. Corium punctate along Cu at apical half and at almost full length of M-R. Exocorium widening towards apex. Membrane well developed, surpassing apex of abdomen, without conspicuous venation. Thoracic pleurites and sternites densely punctate except collar of prosternite, supracoxal lobes, peritreme and posterior lobe of metapleurite. Peritreme auricular with dorsal supporting process elongate, almost straight ( Fig. 3E View FIGURE 3 ), peritremal surface distinct. Fore tibiae club-shaped, middle and hind tibiae rather cylindrical. Tarsal claws evenly curved without basal spur. Unguitractor plate with conspicuous, elongate, curved parempodia-like pads. Abdomen impunctate, integument covered with fine silvery pubescence, genital segments setose. Female ovipositor elongate, bisecting abdominal sternites V–VII.

Measurements (holotype). Total body length: 5.43; head length: 0.58; head width: 1.60; distance between ocelli: 0.35; antennomeres I–IV: 0.35–0.85–0.59–n.a.; labiomeres I–IV: 0.53–0.57–0.63–0.37; length of pronotum: 0.97; width of pronotum: 1.64; length of scutellum: 0.75; width of scutellum: 0.85; length of claval commissure: 0.50.

Diagnosis. The species resembles G. pulchellus sp. nov. but differs from the latter species by the transverse band across pronotal callosities (in G. pulchellus pronotum with longitudinal median band) and peritreme with long, almost straight supporting process (supporting process strongly curved, crescent-shaped in G. pulchellus ).

Etymology. Patronym. The species is named in memory of the late László Papp (1946 – 2021), excellent Hungarian dipterist, member of the Hungarian Academy of Sciences, in honour of his work and influence on Hungarian taxonomic research.

Distribution. Holotype of the species was collected in Baliem valley, Central range, New Guinea ( Fig. 4 View FIGURE 4 ), habitat: Central Range montane rain forests.
