Figs 93–95 View FIGURES 90–98 , 177 View FIGURES 175–183

Diagnosis. Ecnomina gullea   closely resembles E. spinosa   and E. legula   with relatively long mesally directed digitiform projections on the inferior appendages, and superior appendages with apices narrowly separated, but is separated by superior appendages in lateral view length about 1.5 times width, with usually only one robust ventrally directed bristle or spine on lateral processes of segment IX and relatively robust inferior appendages, in lateral view.

Description. Head, body and wings light brown; wings similar to E. legula   ( Fig. 3 View FIGURES 1–6 ). Forewing length about 2.9 times width: male 4.5–5.8 mm, female 4.5–5.5 mm. Forewing fork 2 relatively long, sessile, length about 1.1–1.2 times length of fork 3; fork 3 relatively long, with short footstalk, length fork greater than 8 times length footstalk, footstalk length about 0.5–0.8 times length cross-vein m, r-m and m not contiguous at fork 3 by about 0.5–0.6 times length cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 2.9 times width, fork 2 sessile, length about 1.4–1.5 times length of fork 3.

Male. Segment IX with a pair of long lateral processes with only one ventrally directed, relatively long bristle or spine ( Fig. 93 View FIGURES 90–98 ). Tergum X membranous ( Fig. 95 View FIGURES 90–98 ). Superior appendages in lateral view, very broad near middle, length about 1.5 times width, narrowed in distal third ( Fig. 93 View FIGURES 90–98 ); in dorsal view, fused in basal half, relatively slender in distal half, apices narrowly separated ( Fig. 95 View FIGURES 90–98 ); with a group of stout spines basoventral to base of superior appendages. Phallus generally tube-like, dorso-ventrally flattened ( Fig. 93 View FIGURES 90–98 ). Inferior appendages in ventral view, fused basally, narrowly separated in distal half, with long meso-distally pointed apices ( Fig. 94 View FIGURES 90–98 ); in lateral view, short, robust, length about same as width ( Fig. 95 View FIGURES 90–98 ).

Female. Genitalia with a single elongate and relatively robust or bladelike mesal process on sternite VIII, process slightly broadened distally; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender ( Fig. 177 View FIGURES 175–183 ).
