Diagnosis. Ecnomina manicula   shares with E. kepin   the character of two pairs of relatively slender dorsal processes on tergum X, but differs in that the margin of the fused inferior appendages is not entire but has distolateral processes.

Description. Head, body and wings brown, abdomen paler ventrally; wings similar to E. legula   ( Fig. 3 View FIGURES 1–6 ). Forewing length about 3.0–3.2 times width: male 3.7–3.9 mm, female 3.7 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 3 between 6.3–9.4 times length footstalk, footstalk length between 0.6–1.0 times length cross-vein m, r-m and m not contiguous at fork 3 by about 0.5–1.0 times length of cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 3.3 times width, fork 2 sessile, length about 1.5–1.6 times length of fork 3.

Male. Tergum X membranous, short with two pairs of slender processes mesally ( Fig. 125 View FIGURES 123–128 ). Superior appendages laterally compressed; in lateral view robust, length nearly 3 times width, dilated slightly in distal third ( Fig. 123 View FIGURES 123–128 ); in dorsal view, relatively slender, length about 6 times width, slightly incurved distally, with a slender mesal spine subapically ( Fig. 125 View FIGURES 123–128 ). Phallus simple, tube-like with associated processes dorsally and ventro-laterally ( Fig. 123 View FIGURES 123–128 ). Inferior appendages robust, strongly dorso-ventrally flattened, fused in basal half, with two pairs of slender, ‘finger-like’ disto-lateral processes ( Figs 123, 124 View FIGURES 123–128 ).

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