GRACILIPSODES GRANDIS SP. NOV. ( FIGS 5 View Figure 5 , 13 View Figure 13 )

Diagnosis: This is the largest species in the genus. It is separated from the other species by the tibial spur formula 1, 1, 1 and, in the genitalia, by the pre-apical lateral processes of tergum X originating at the mid length of tergum X.

Description, male: Body and wings medium brown. Tibial spur formula 1, 1, 1. Hind tibiae each with 31–35 small black spines (N = 3). Forewing ( Fig. 5A View Figure 5 ): length 6.5–9.7 mm (N = 3); apex rounded; forks 1 and 5 present; crossvein m–cu short and at a right angle to M. Hindwing ( Fig. 5B View Figure 5 ): length 4.5–6.8 mm (N = 3); apex rounded; forks 1, 3, and 5 present; costa with about 39 hamuli; crossvein r–m convex.

Genitalia: Segment IX annular, laterally setose, narrowest at bases of superior appendages; tergite IX laterally about as wide as sternite IX ( Fig. 5C View Figure 5 ); central part of tergite IX posterior margin produced posteroventrad ( Fig. 5C, D View Figure 5 ). Superior appendages setose, flattened dorsoventrally, about as long as tergum X, apices nearly acute in dorsal view ( Fig. 5D View Figure 5 ). Tergum X membranous; median process entire, wide basally, tapering to nearly acute apex in lateral view ( Fig. 5C View Figure 5 ); apex with U-shaped notch in dorsal and ventral views ( Fig. 5D, E View Figure 5 ); pre-apical lateral processes shorter than median process, produced at mid length, sclerotized, digitate, oriented posterad ( Fig. 5C, E View Figure 5 ). Inferior appendages each bipartite, setose ( Fig. 5C View Figure 5 ); basal part wide in ventral view, mesally concave, and produced posteromesally into a broad, distally tapering, apically rounded lip, bearing small dorsal spines ( Fig. 5C, E View Figure 5 ); apical part of each inferior appendage digitate, curving mesally; in lateral view, parallel-sided, apex rounded, with about 35 mesal spines ( Fig. 5C View Figure 5 ); mesal process bearing six strong spines ( Fig. 5D View Figure 5 ). Harpago: sclerotized and slender ( Fig. 5C View Figure 5 ). Phallic apparatus simple ( Fig. 5F, G View Figure 5 ); phallicata basally tubular, fused with phallobase, apex truncate; bent about 45° ventrad at mid length; apex with pair of broad, sclerotized, lateral processes, being produced ventrally, curved medially, and with apices broadly rounded ( Fig. 5F, G View Figure 5 ); phallotheca extended; phallotremal sclerite U-shaped, curving anteriorly at apex ( Fig. 5G View Figure 5 ).

Holotype (male): New Caledonia, Province Sud, Mt Dzumac, source stream of Ouinné River , near cross point to mountain track, 22°02.439’S, 166°28.646’E, 805 m a.s.l., 18 November–4 December 2003, Malaise trap, loc#029 (Johanson). GoogleMaps

Paratypes: One male, same data as holotype. One male, New Caledonia, Province Sud, Haute Yaté fauna reserve, 1760 m south of bridge Pont Perignon , 50 m upstream of bridge over stream, 22.14954°S, 166.701211°E, 180 m a.s.l., 14 December 2003 – 13 January 2004, Malaise trap, loc#081 (Johanson) GoogleMaps .

Distribution: Province Sud, southern area.

Etymology: grandis , from Latin, grand, large; referring to the large size of this species in comparison with the other species within the genus.
