description: <i>Ecnomina alluna</i> sp. nov. Figs 129–131, 185 Diagnosis. <i>Ecnomina alluna</i> closely resembles the other three species in the group in possessing the slender lateral pair of dorsal processes on tergum X and shares with <i>E. alluna</i> and <i>E. bula</i> laterally incised fused or joined inferior appendages. It is distinguished from <i>E. anulla</i> by the inferior appendages which in ventral view are less strongly excised laterally and the apices are straight sided, not dilated. Description. Head, body and wings brown, abdomen paler ventrally; wings similar to <i>E. legula</i> (Fig. 3). Forewing length about 2.9–3.1 times width: male 3.7–4.6 mm; female 3.6–4.3 mm. Forewing fork 2 relatively long, sessile, length about 1.2–1.3 times length of fork 3; fork 3 relatively long, with short footstalk, fork greater than 5 times length footstalk, footstalk length about 0.7–0.9 times length cross-vein m, r-m and m nearly contiguous at footstalk fork 3, r-m and m separated by about 0.8–1.1 times length of cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about 1.9 times length of fork 4. Hindwing length about 3.2 times width, fork 2 sessile, length about 1.5–1.6 times length of fork 3. Male Tergum X membranous, fused basally, with two pairs of dorsal processes, a robust, mesal pair and a slender pair laterally (Fig. 131), a ventral process also present. Superior appendages robust; in lateral view, broad basally, tapered in distal half, length about 1.6 times width (Fig. 129); in dorsal view, length about three times width, with several spines in distal third, dilated slightly distally (Fig. 131). Phallus down turned slightly apically (Fig. 129). Inferior appendages short, broad basally; in ventral view, fused or joined, length about 0.7 times width, rounded baso-laterally, narrowed about middle, excised disto-laterally, truncate distally (Fig. 130); in lateral view, robust basally, upturned slightly and slender distally (Fig. 129). Female. Genitalia with a single short, robust mesal process on sternite VIII; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender (Fig. 185). <b>Holotype male</b>: New South Wales, ' Mooraback', Werrikimbe NP (about 31°15'S, 152°11'E), 980 m, 6 Dec 1986, G. Theischinger (NMV, T-19760). <b>Paratypes</b>: New South Wales. 8 males (specimen CT-453 figured), 9 females (specimen CT-505 figured), collected with holotype (NMV). Other material examined: New South Wales. 2 males, 3 females, Rosebank, 11 Jan 1958, collector? (ANIC). Etymology. <i>Alluna</i> - eastern Australian Aboriginal word for two together (fused inferior appendages). Remarks. <i>Ecnomina alluna</i> has been collected from north-eastern New South Wales (latitudinal range 28°40'-31°14'-S).
