description: GRACILIPSODES GRANDIS SP. NOV. (FIGS 5, 13) <i>Diagnosis:</i> 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. <i>Description, male:</i> Body and wings medium brown. Tibial spur formula 1, 1, 1. Hind tibiae each with 31–35 small black spines (<i>N</i> = 3). Forewing (Fig. 5A): length 6.5–9.7 mm (<i>N</i> = 3); apex rounded; forks 1 and 5 present; crossvein m–cu short and at a right angle to M. Hindwing (Fig. 5B): length 4.5–6.8 mm (<i>N</i> = 3); apex rounded; forks 1, 3, and 5 present; costa with about 39 hamuli; crossvein r–m convex. <i>Genitalia:</i> Segment IX annular, laterally setose, narrowest at bases of superior appendages; tergite IX laterally about as wide as sternite IX (Fig. 5C); central part of tergite IX posterior margin produced posteroventrad (Fig. 5C, D). Superior appendages setose, flattened dorsoventrally, about as long as tergum X, apices nearly acute in dorsal view (Fig. 5D). Tergum X membranous; median process entire, wide basally, tapering to nearly acute apex in lateral view (Fig. 5C); apex with U-shaped notch in dorsal and ventral views (Fig. 5D, E); pre-apical lateral processes shorter than median process, produced at mid length, sclerotized, digitate, oriented posterad (Fig. 5C, E). Inferior appendages each bipartite, setose (Fig. 5C); 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); apical part of each inferior appendage digitate, curving mesally; in lateral view, parallel-sided, apex rounded, with about 35 mesal spines (Fig. 5C); mesal process bearing six strong spines (Fig. 5D). Harpago: sclerotized and slender (Fig. 5C). Phallic apparatus simple (Fig. 5F, G); 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); phallotheca extended; phallotremal sclerite U-shaped, curving anteriorly at apex (Fig. 5G). <i>Holotype (male):</i> 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). <i>Paratypes:</i> 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). <i>Distribution:</i> Province Sud, southern area. <i>Etymology: grandis</i>, from Latin, grand, large; referring to the large size of this species in comparison with the other species within the genus.
