Diagnosis. Ecnomina wanarra can be separated from all other species in the genus by the pair of distinctive, very long and slender inferior appendages.

Description. Head and body pale fawn, wings pale (faded?); wings similar to E. legula ( Fig. 3 View FIGURES 1–6 ). Forewing length about 3.0 times width: male 4.9 mm. Forewing fork 2 relatively long, sessile, length about 1.3 times length of fork 3; fork 3 relatively long with short footstalk, length greater than 6 times length footstalk, footstalk length about 0.6–0.9 times length cross-vein m, r-m and m not contiguous at fork 3 by about same length as cross-vein m; fork 4 similar length to fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 2.9 times width, fork 2 sessile or with very short footstalk, fork length about 1.9–2.0 times length of fork 3.

Male. Tergum X membranous ( Fig. 107 View FIGURES 99–107 ). Superior appendages in lateral view, sub rectangular, length about 3 times width ( Fig. 105 View FIGURES 99–107 ); in dorsal view, relatively robust, length about 3 times width ( Fig. 107 View FIGURES 99–107 ). Phallus generally tube-like, slightly dorso-ventrally flattened ( Figs 105, 106 View FIGURES 99–107 ). Inferior appendages very long and slen- der; in ventral view, length about eleven times width, slightly incurved distally ( Fig. 106 View FIGURES 99–107 ); in lateral view, length about ten times width, slightly angled near middle ( Fig. 105 View FIGURES 99–107 ).

Female. Unknown.

Holotype male (specimen CT-482 figured): Queensland, Carnarvon Gorge Nat. Pk, 25°15'S, 148°24'E, 12 Nov 1990, G. Theischinger ( NMV, T-19713). GoogleMaps
