Diagnosis. Ecnomina kepin shares with E. manicula 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 entire and without distolateral processes.

Description. Head and body brown, wings light brown, abdomen paler ventrally; wings similar to E. legula ( Fig. 3 View FIGURES 1–6 ). Forewing length about 2.7–2.9 times width: male 4.3–4.4 mm. Forewing fork 2 relatively long, sessile, length about 1.1–1.2 times length of fork 3; fork 3 relatively long, with very short footstalk, fork between 0.2–0.4 times length footstalk, footstalk length greater than 10 times length cross-vein m, r-m and m not contiguous by about 0.5–0.6 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 times width, fork 2 sessile, length about 1.3–1.5 times length of fork 3.

Male. Tergum X membranous, short with two pairs of slender processes mesally ( Fig. 122 View FIGURES 114–122 ). Superior appendages laterally compressed; in lateral view robust, length about 2.5 times width, narrowed in distal third ( Fig. 120 View FIGURES 114–122 ); in dorsal view, relatively slender, length about 4.5 times width, slightly incurved distally, with a robust mesal spine subapically ( Fig. 122 View FIGURES 114–122 ). Phallus simple, tube-like, relatively slender ( Fig. 120 View FIGURES 114–122 ). Inferior appendages robust, strongly dorso-ventrally flattened; in ventral view fused to form a single broadly triangular plate, length about same as width ( Fig. 121 View FIGURES 114–122 ); in lateral view, length about 3 times width ( Fig. 120 View FIGURES 114–122 ).
