description: <i>Daternomina birrarung</i> sp. nov. Figures 7–9, 55 Diagnosis. <i>Daternomina birrarung</i> is distinguished from other species in the genus by having the superior appendages in lateral view branched, the ventral branch being strong. Description. Head, body and wings brown; wings similar to <i>D. irrorata</i> (Fig. 1). Forewing length about 3.1 times width: male 4.4–5.2 mm, female 5.8 mm. Forewing fork 2 relatively long, sessile, about 1.5–1.9 times length of fork 3, nygma present; fork 3 relatively long, length about 1.8–3.2 times length footstalk, footstalk length about 1.5–2.1 times length cross-vein m; r-m and m displaced at fork 3 by about 1.6–1.9 times length cross-vein m; fork 4 length similar to fork 3; fork 5 long, about 1.8 times length of fork 4. Hindwing length about 3 times width; fork 2 sessile, length about 1.7–2.0 times length of fork 3. Male. Tergum X membranous with a pair of small disto-mesal processes (Fig. 9). Superior appendages laterally compressed; in lateral view, branched, ventral branch slightly less robust than dorsal branch (Fig. 7); in dorsal view, relatively slender, length about 6 times width, with a small process and spines on inner surface (Fig. 9). Phallus robust, generally tube-like, with spines embedded apically; a single, robust process (phallic guide) arising from near the base of the inferior appendages (Fig. 7). Inferior appendages small; in ventral view, fused basally, slender paired apices separated narrowly by a mesal split (Fig. 8); in lateral view, narrowed at about midpoint (Fig. 7). Female. Genitalia with a pair of large, slightly divergent 'tongue-shaped' lobes on sternite VIII (Fig. 55). <b>Holotype male</b>: Victoria, Yarra R., 2 km N Wonga Park (about 37°44'S, 145°15'E), 23 Feb. 1976, A.N.
