Australosagola jiwooki sp. nov. Figs 1 G, 8, 14 Type material. Holotype. Australia: Victoria: • ♂ (aedeagus dissected; ANIC), “ AUSTL.: VIC.: Mt. Buffalo / N. P., above Eurobin Point / 820 m 36.42S 146.50E / 23. I. 1987 / wet sclerophyll forest // A. Newton & M. Thayer 805 / FMHD#87-202 / berl., leaf & log / litter, forest floor ” (actual coordinate data: 36°42'S, 146°50'E = - 36.70, 146.83). Paratype (n = 1; 1 ♂). Australia: Victoria: • 1 ♂ (slide-mounted; FMNH), same data as holotype. Diagnosis. Australosagola jiwooki sp. nov. can be distinguished from other Australosagola species by the weakly defined frontal fovea (Fig. 8 B, E, white arrows), and by the combination of a median preapical tubercle and small mediolateral clusters of spines at the apex of male sternite 5 (VII; Fig. 8 C, H). Male description. Length 2.4 mm. Body reddish-brown. Head. Head in dorsal view, shallowly impressed at base of frontal rostrum (Fig. 8 B, E). Vertexal foveae well-developed (Fig. 8 B, E). Antennomere 1 subconical and longer than wide; 2 rounded and longer than wide; 3 smallest, subquadrate and transverse; 4–6 subquadrate and longer than wide; 7 subquadrate and as long as wide; 8 subquadrate and transverse; 9 subquadrate and as long as wide; 10 trapezoidal and transverse (Fig. 8 A, D). Thorax. Prothorax slightly broader than long (Fig. 8 F). Elytra with two subbasal elytral foveae, three basal elytral foveae (1 being fovea at base of sutural stria), discal elytral foveae with short discal striae, and fovea in sutural striae. Hind wings fully developed. Metatrochanter with ventral margin convex (Fig. 8 C, G). Abdomen. Only abdominal sternite 5 (VII) with median impression (Fig. 8 C), 5 (VII) with pair of setal clusters at apex of median projection of posterior margin (Fig. 8 C, H, black arrows), with median, preapical tubercle (Fig. 8 C, H, white arrows). Genitalia. Length 0.48 mm, aedeagus symmetrical, in basovental view with lateral margins roughly parallel, in lateral view apical 1 / 2 of median lobe greatly inflated; median lobe with lateral margins sub-angulate at apex in basoventral view (Fig. 8 J), pair of projections at midpoint of median lobe straight in lateral view, slightly sinuate in ventral view, slightly longer than parameres (Fig. 8 J, K). Tubercles at base of median lobe bent near base in lateral view, thickly V-shaped in ventral view (Fig. 8 I, K). Phallobase small with lateral margins evenly rounded in ventral view, flat, short, and evenly curved in lateral view (Fig. 8 I, K). Female sexual characters. Female unknown. Comment. Australosagola jiwooki has a small frontal fovea that is slightly impressed at the base of the frontal rostrum around the frontal fovea (Fig. 8 B). This species also has a unique modified form at the apex of abdominal sternite 5 (VII), a pair of median apical setal clusters that have only 6–8 setae together with a preapical median tubercle (Fig. 8 H, white and black arrows). Etymology. This species is named for a curculionid specialist who has been an enthusiastic supporter of this study, Ji-Wook Kim. Distribution. Victoria (Fig. 14, red square). Habitat. Both specimens were collected by sifting leaf, log, and forest floor materials in a wet sclerophyll forest.
