Diagnosis. Ecnomina bula   is distinguished from others in the group by the apices of the fused inferior appendages, which in ventral view are narrowly separated by a V-shaped notch.

Description. Head, body and wings brown, abdomen paler ventrally; wings similar to E. legula   ( Fig. 3 View FIGURES 1–6 ). Forewing length about 3.0–3.1 times width: male 3.5–4.3 mm; female 3.9–4.4. Forewing fork 2 relatively long, sessile, length about 1.3–1.4 times length of fork 3; fork 3 relatively long, with short footstalk, fork about 4 times length footstalk, footstalk length about 1.3–1.4 times length cross-vein m, r-m and m nearly contiguous at fork 3, r-m and m separated by about 0.8–1.0 times length of cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about twice length of fork 4. Hindwing length about 3.3–3.4 times width, fork 2 sessile, length about 1.8 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. 137 View FIGURES 129–137 ), a ventral process also present. Superior appendages in lateral view, robust, broad basally, tapered in distal half, length about twice width ( Fig. 135 View FIGURES 129–137 ); in dorsal view, length about 3 times width, with several spines in distal third, dilated slightly distally ( Fig. 137 View FIGURES 129–137 ). Phallus with slightly down turned ventral process and dorsal process apically ( Fig. 135 View FIGURES 129–137 ). Inferior appendages short, fused basally, dorso-ventrally flattened; in ventral view, length about same as width, broad basally, rounded baso-laterally, excised slightly disto-laterally, with apices narrowly separated by small V-shaped notch ( Fig. 136 View FIGURES 129–137 ); in lateral view, relatively slender, tapered slightly distally ( Fig. 135 View FIGURES 129–137 ).

Female. Genitalia with a single short, robust mesal process, slightly truncate apically, on sternite VIII; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender ( Fig. 187 View FIGURES 184–195 ).
