Australosagola doohyungi sp. nov. can be distinguished from other Australosagola species by the median lobe of the aedeagus being constricted at the midpoint (Fig. 10 L), and with this being the only species lacking the projections at the midpoint of the median lobe (Fig. 10 L – N). Male description. Length. 2.0– 2.3 mm. Head. Head slightly broader than long; frontal sulcus with contiguous margins, area posterior to frontal rostrum impressed around frontal fovea (Fig. 10 C, H). Vertexal foveae well-developed (Fig. 10 C, H). Tempora posterolaterally angulate. Antennomere 1 longer than wide; 2 subquadrate and longer than wide; 3 subconical and longer than wide; 4–7 subquadrate and longer than wide; 8 somewhat globose and longer than wide; 9 and 10 somewhat globose and slightly longer than wide (Fig. 10 A, G). Thorax. Prothorax slightly broader than long, widest at midpoint (Fig. 10 I). 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 slightly angulate (Fig. 10 E, J). Abdomen. Abdominal sternites 4 and 5 (VI – VII) broadly convex (Fig. 10 E, K). Tergite 2 (V) ~ 1 / 2 length of 3 (VI) (Fig. 10 E, K). Abdominal sternite 5 (VII) lacking modifications. Genitalia. Length 0.39 mm, aedeagus symmetrical, with basal 1 / 2 of median lobe slender, constricted to middle, apical 1 / 2 expanded, widest at apical 1 / 3, then narrowing to subtruncate apex with blunt median point, in lateral view apex elongate and acutely pointed (Fig. 10 N), with pair of blunt preapical spines (Fig. 10 L, black arrow). Preapex of median lobe with apically divided small and blunt process best seen in basoventral and lateral views (Fig. 10 M, N, black arrows). Parameres long and extending almost to apex of median lobe, projection at base of median lobe evenly curved apically, phallobase in ventral view with margins evenly rounded (Fig. 10 L, M), in lateral view flattened, slightly curved (Fig. 10 M). Female sexual characters. Head as long as wide (Fig. 10 D). Metatrochanter with posterior margin convex (Fig. 10 F). Comment. This species has a unique aedeagus that lacks projections at the midpoint of the median lobe. It could be that the median lobe is only expanded at the apex of the median lobe, so that the small and blunt end projection at the apex of the median lobe could be the ancestral or derived version of this projection, which is seen in other species. Etymology. This species is named for respected mentor of the first author who is a specialist in ecology and ethology, Dr. Doo-Hyung Lee. Distribution. Western Australia (Fig. 14, blue circles). Habitat. Specimens of this species were collected by malaise traps, flight intercept traps (F. I. T.), or by sifting bark, leaf, fungi, or logs in wet sclerophyll Eucalyptus forests, or by sifting coastal scrub litter.
