NOV. ( FIGS 3 , 13 ) Diagnosis: This species is distinguished from G. lanceolatus sp. nov. , G. grandis sp. nov. , G. psocopterus , and G. similis by the tibial spur formula 2, 2, 2, and the presence of a pair of pre-apical lateral processes of tergum X, originating from the apical half of the segment. It is separated from G. aurorus sp. nov. , G. koghiensis sp. nov. , and G. aoupiniensis sp. nov. in the genitalia, by the shorter lateral processes of tergum X, and in the forewing, by the shorter crossvein m–cu oriented at almost a right angle to M. It is distinguishable from G. robustus sp. nov. by its slightly smaller size, in the genitalia, by the longer superior appendages, and by the apical part of the inferior appendage being slender and parallel-sided. Description, male: Body golden yellowish brown. Wings greyish brown. Tibial spur formula 2, 2, 2. Hind tibiae each with 15–19 small black spines ( N = 3). Forewing ( Fig. 3A ): length 6.8–7.2 mm ( N = 3), apically rounded; forks 1 and 5 present; crossvein m–cu about as long as or slightly shorter than crossvein r–m, and at right angle with M. Hindwing ( Fig. 3B ): length 5.0– 5.2 mm ( N = 3), apex nearly acute; forks 1, 3, and 5 present; crossvein r–m convex; costa with 20–23 hamuli. Genitalia: Segment IX annular, laterally setose, narrowest at bases of superior appendages; tergite IX about as broad as sternite IX in lateral view ( Fig. 3C ). Superior appendages setose, flattened dorsoventrally, slightly longer than tergum X, apices rounded in dorsal view ( Fig. 3D ). Tergum X membranous; median process entire, basally wide, apex rounded, dorsal margin slightly concave in lateral view ( Fig. 3C ), apex with shallow notch in dorsal and ventral views ( Fig. 3D, E ); pre-apical lateral process shorter than median process, produced at apical half, sclerotized, digitate, directed posterolaterad, and slightly curving dorsally ( Fig. 3C ). Inferior appendages each bipartite, setose; basal part wide in lateral and ventral views ( Fig. 3C, D ), mesally concave, produced posteromesally into a broad, apically rounded lip, bearing small dorsal spines ( Fig. 3C, E ); apical part of each inferior appendage digitate, curving mesally, in lateral view parallel-sided, apex rounded, with 30–40 mesal spines ( Fig. 3C ); mesal process with between five and seven strong spines ( Fig. 3D ). Harpago small, slender, club-shaped, apex nearly acute ( Fig. 3C ). Phallic apparatus simple ( Fig. 3F, G ), phallicata basally tubular, fused with phallobase, apex truncate; bent about 45° ventrad at mid length; apical part with pair of sclerotized, broad lateral processes, produced ventrad, curved somewhat medially, and broadly rounded at apex ( Fig. 3F ); phallotremal sclerite U-shaped ( Fig. 3G ). Holotype (male): New Caledonia , Province Nord , Col d’Amieu , 20 km north of Sarraméa , 306 m a.s.l. , small river, 21°33.877′S , 165°49.922′E , 2 December 2001 , light trap , loc#27 ( Johanson , Pape & Viklund ). Paratypes : One male, same data as holotype. One male, New Caledonia , Province Sud , Sarraméa, 220 m a.s.l. , 19 November 2001 , light trap , loc#10 ( Johanson , Pape & Viklund ); one male , New Caledonia , Province Nord , Xwê Dachava Stream , Rembai Mt , 21°34.854′S , 165°49.478′E , 317 m a.s.l. , 5–12 January 2004 , Malaise trap , loc#108 (Johanson) . Distribution: Central Grande Terre. Etymology: From Latin, aureus , golden; named for the golden, yellowish brown body colour of the species.
