Newton & M. Thayer 767. Diagnosis. This species can be distinguished from other species by the following characters: antennomere 3 transverse, 4–7 subquadrate (Fig. 11 A, B, G), apex of aedeagus lacking sharp projection in lateral view (Fig. 11 N, black arrow). Male description. Length. 2.2–2.3 mm. Head. Head with margins of frontal sulcus contiguous, area posterior to frontal rostrum deeply impressed around frontal fovea; broader than long, widest across eyes (Fig. 11 C). Vertexal foveae well-developed (Fig. 11 C). Antennomere 1 cylindrical and longer than wide; 2 subquadrate and longer than wide; 3 smallest, subquadrate and flattened; 4–8 subquadrate and as long as wide; 9 and 10 subquadrate and transverse (Fig. 11 A). Thorax. Prothorax as long as wide. Elytra with three basal elytral foveae (1 being fovea at base of sutural stria), discal elytral foveae with short discal striae, and fovea in sutural striae. Metatrochanter with ventral margin angulate (Fig. 11 E). Abdomen. Abdominal sternites 4 and 5 (VI – VII) largely medially impressed (Fig. 11 E). Abdominal tergite 2 (V) ~ 2 / 3 length of tergite 3 (VI; Figs 1 J, 2 H). Genitalia. Length 0.44 mm, aedeagus symmetrical, preapex of median lobe laterally angulate, then evenly convergent to broad truncate apex with median point in ventral view (Fig. 11 L, black arrow), in basoventral view apical 1 / 3 broadly lobed with apices broadly and bluntly rounded (Fig. 11 M). Apex of median lobe with small median spine visible in ventral view (Fig. 11 L, black arrow); area inflated and broadly rounded in lateral view (Fig. 11 N); W-shaped projection at base of median lobe distinct in ventral and basoventral views (Fig. 11 L, M); phallobase with lateral margins broadly rounded (Fig. 11 L, M), slightly curved in lateral view, with basal margin hooked (Fig. 11 N). Female sexual characters. Antennomere 1 cylindrical and longer than wide; 2 slightly subconical and longer than wide; 3 smallest, transverse; 4–10 larger and transverse (Fig. 11 B, G). Comment. Because only a single male specimen was available, we could not confirm the presence of subbasal elytral foveae. However, in females we were able to confirm the presence of two subbasal elytral foveae, as is found in the other species. Specimens of A. jungjooni sp. nov. can be distinguished from other Australosagola species, except A. minsangi, by the presence of transverse antennomere 3 for both sexes. Australosagola jungjooni sp. nov. can be separated from A. minsangi by antennomeres 4–7 of A. jungjooni being more subquadrate, while these antennomeres are greatly transverse, almost disc-like, for A. minsangi (Figs 6 A, B, G, 11 A, B, G). Also, the aedeagus of A. jungjooni resembles that of A. minsangi, but the apical part of the aedeagus in lateral view is more acutely projecting in A. minsangi (Fig. 6 N), while for A. jungjooni it is quite bulbous (Fig. 11 N, black arrow). Etymology. This species is named for a respected mentor of the first author, an insect ecology specialist, Dr. Jung-Joon Park. Distribution. New South Wales (Fig. 13, black stars). Habitat. Specimens of this species were collected by sifting leaf and grass litters at the base of Eucalyptus trees, or were taken by flight intercept traps (F. I. T.) in Eucalyptus woodlands or warm-temperate rainforests.
