description: <i>Daternomina loowa</i> sp. nov. Figures 25–27, 58 Diagnosis. <i>Daternomina loowa</i> can be distinguished from closely related <i>Daternomina</i> species, <i>D. trulla</i> and <i>D. quasitrulla</i>, by having truncate superior appendages and fused, short inferior appendages with relatively shallow notch apically, dividing at most the distal third. Description. Head, body and wings brown; wings similar to <i>D. irrorata</i> (Fig. 1). Forewing length about 2.8–3.0 times width: male 4.4 mm, female 4.6 mm. Forewing fork 2 relatively long, sessile, length about 1.7 times length of fork 3, nygma present; fork 3 relatively long, length about 2.3–2.5 times length footstalk, footstalk length about 1.5–1.7 times length cross-vein m; r-m and m displaced at fork 3 by about 1.8 times length cross-vein m; fork 4 length similar to fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 3 times width, fork 2 sessile, length about 1.5 times length of fork 3. Male. Tergum X membranous with a pair of small disto-mesal processes (Fig. 27). Superior appendages strongly laterally compressed; in lateral view, broad, truncate distally, length about 2.5 times width (Fig. 25); in dorsal view, relatively slender, length about 5 times width, with a group of spines on inner surface (Fig. 27). Phallus generally tube-like, with a pair of long embedded spines; with a pair of slender, curved processes (phallic guides) arising from near the base of the inferior appendages (Fig. 25). Inferior appendages small, fused, strongly dorso-ventrally compressed; in ventral view, short, rounded laterally, with a shallow, wide Vshaped notch distally (Fig. 26); in lateral view, relatively short and robust (Fig. 25). Female. Genitalia with a pair of large, narrowly separated 'tongue-shaped' lobes on sternite VIII, with characteristic 'small dark triangle' visible mesally (Fig. 58). <b>Holotype male</b>: Queensland, Seary's Ck, Rainbow Beach, 25º58'S, 153º04'E, 9 Jan 1986, G. Theischinger (NMV, T-19572, specimen CT-457 figured). <b>Paratypes</b>: Queensland. 4 females (specimen CT-493 figured), collected with holotype; 7 females, same loc. and coll., 6 Dec 1984 (NMV). Other material examined: Queensland. 3 females, same loc. and coll. as holotype, 9 Feb 1987; 1 female, Blue Lake, N Stradbroke Isl., 27 May 1973, H. Burton; 1 female, Myora Springs, N Stradbroke Isl., 3 Sep 1974, A. Bensink; 1 female, same loc., 22 Mar 1969, J. Attwood; 1 female, Dunwich (N Stradbroke Isl.), 4 May 1969, lt tr., M. Cox.
