Australosagola sunheei Choi, Chandler & Park, 2025, sp. nov.

Australosagola sunheei sp. nov. Figs 1 H, 2 E, 9, 13 Type material. Holotype. Australia: South Australia: • ♂ (aedeagus dissected; ANIC), “ AUSTL: S. Austl., 10 / km SE Adelaide, / Belaire Rec. Pk., / 29 - VI- 1983 // FMHD#83-248, damp / leaf litter, L. E. / Watrous ”. Paratype (n = 1; 1 ♀). Australia: South Australia: • 1 ♀ (slide-mounted; UNHC), same data as holotype. Diagnosis. Australosagola sunheei sp. nov. can be distinguished by the following characters: head being widest at tempora (Fig. 9 C, D, H), median lobe of aedeagus with prominent broad projection at middle (Fig. 9 N, black arrow). Male description. Length. 2.3–2.5 mm. Head. Head with frontal sulcus and area around frontal fovea concave in dorsal view. Vertexal foveae well-developed (Fig. 9 C). Antennomere 1 cylindrical and longer than wide; 2 slightly subconical and longer than wide; 3 subconical, smallest and slightly longer than wide; 4–8 subquadrate and as long as wide; 9 and 10 subquadrate and transverse (Fig. 9 A, G). Thorax. Prothorax slightly broader than long, widest at midpoint (Fig. 9 I). Elytra with two subbasal elytral foveae, three basal elytral foveae (one being fovea at base of sutural stria), discal elytral foveae with short discal striae, and fovea in sutural striae. Metatrochanter with posterior margin smoothly convex (Fig. 9 E). Abdomen. Only abdominal sternite 5 (VII) medially impressed; with pair of setal clusters at apex of median projection (Fig. 9 E). Abdomen with visible tergite 2 (V) ~ 2 / 3 length of 3 (VI) (Fig. 1 H). Genitalia. Length 0.36 mm, aedeagus symmetrical, projection of median lobe broadly expanded laterally at middle in basoventral view (Fig. 9 N, black arrow), projection longer than parameres (Fig. 9 O). Projections at base slightly curved in lateral view, heart-shaped (chordate) in ventral view, phallobase with lateral margins evenly rounded in ventral view, flat, short, and evenly curved in lateral view (Fig. 9 M – O). Female sexual characters. Eyes smaller than those of male (Fig. 9 D). Hind wings comparatively small (Fig. 9 J). Abdominal sternites convex (Fig. 9 F); lacking setae at apex of abdominal sternite 5 (VII; Fig. 9 F, L). Comment. Australosagola sunheei can be separated from allied A. yongsooni by the features of the aedeagus, which in A. sunheei has a broader median projection of the median lobe than does A. yongsooni (Figs 9 N (black arrow), 12 N). Etymology. This species is named for a respected mentor of the first author who is a specialist in biological control, Dr. Sun-Hee Hong. Distribution. South Australia (Fig. 13, black hexagon). Habitat. Specimens of this species were collected from damp leaf litter.
