description: <i>Ecnomina scutica</i> sp. nov. Figs 4, 5, 63–65, 173 Diagnosis. <i>Ecnomina scutica</i> can be separated from all other species in the genus by the distinctive long whiplike structure distally on segment IX. Description. Head, body and wings dark brown; wings partly drawn (Fig. 5), similar to <i>E. legula</i> (Fig. 3). Forewing length about 3 times width: male 5.0– 5.8 mm, female 5.6–6.7 mm. Forewing fork 2 relatively long, sessile or with short footstalk, footstalk length up to 0.4 times length cross-vein m, nygma present, length fork 2 about 1.2–1.3 times length of fork 3; fork 3 relatively long, sessile or with short footstalk, length fork 3 at least ten times length footstalk, footstalk length 0–0.3 times length cross-vein m; r-m and m not contiguous at fork 3 by about 1.7 times length cross-vein m; fork 4 slightly shorter than fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 2.7 times width, fork 2 sessile or with short footstalk, length footstalk up to 0.7 times length cross-vein m, fork 2 about 1.2–1.3 times length of fork 3. Male. Segment IX with robust lateral extension with very long and slender whip-like process dorso-distally. Tergum X membranous, with two relatively long and slender diverging processes (Figs 63, 65). Superior appendages reduced, slightly dorso-ventrally compressed; in lateral view, slender, length about 6 times width (Fig. 63); in dorsal view, length about 3.5 times width, bifid distally (Fig. 65). Phallus generally tube-like, slightly compressed distally; with a single, robust, strongly down curved or hooked process (phallic guide) arising from near the base of the inferior appendages (Fig. 63). Inferior appendages in ventral view, fused basally, with wing-like extensions disto-laterally (Fig. 64); in lateral view, ovoid, dilated distally (Fig. 63). Female. Genitalia with a single elongate and relatively slender mesal process on sternite VIII; segment IX relatively long, tapered slightly distally; segment X relatively short and segments IX and X relatively slender, with a few pairs of hairs on segment X (Fig. 173). <b>Holotype male</b>: Victoria, Bells Clearing, 6 km S of Aberfeldy (about 37°44'S, 146°22'E), 9 Feb 1977, A.A.
