Figs 147–149 View FIGURES 144–152 , 190 View FIGURES 184–195

Diagnosis. Ecnomina ramosa is distinguished from other species in the group, by the pair of bifid processes on tergum X.

Description. Head, body and wings light brown; wings similar to E. merki ( Fig. 172 View FIGURES 168–174 ). Forewing length about 2.6–2.8 times width: male 2.6–3.3 mm, female 2.8–3.5 mm. Forewing fork 2 relatively long, sessile, length about 1.5–1.6 times length of fork 3; fork 3 relatively short, with long footstalk, length fork about 1.8– 2.4 times length footstalk, footstalk length about 1.5–2.2 times length cross-vein m, r-m and m nearly contiguous at footstalk fork 3, r-m and m separated by about 0–0.4 times length of cross-vein m; fork 4 slightly shorter than fork 3; fork 5 long, length about twice length of fork 4; Hindwing length about 3 times width, fork 2 sessile, length about 1.7–2.1 times length of fork 3.

Male Tergum X membranous, with one pair of relatively robust bifid dorsal processes, inner branch longer than outer ( Fig. 149 View FIGURES 144–152 ). Superior appendages in lateral view, sub-rectangular, length about three times width ( Fig. 147 View FIGURES 144–152 ); in dorsal view, length about 5 times width, with several mesal spines in distal third, dilated slightly distally ( Fig. 149 View FIGURES 144–152 ). Phallus simple, tube-like, relatively slender, dilated slightly apically ( Fig. 147 View FIGURES 144–152 ). Inferior appendages short; in ventral view, fused in basal two thirds, dilated and truncated distally, with oval excision meso-distally, length about two thirds width ( Fig. 148 View FIGURES 144–152 ); in lateral view, robust, slightly dilated and truncated distally, length about twice width ( Fig. 147 View FIGURES 144–152 ).

Female. Genitalia with a single short, digitiform mesal process on sternite VIII; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender ( Fig. 190 View FIGURES 184–195 ).

Etymology. Ramosa - Latin word for branching (processes on tergum X).

Remarks. Ecnomina ramosa has been collected from four sites in north-eastern Queensland (latitudinal range 18°57'- 19°18'S).
