Diagnosis. Ecnomina gippslandica most closely resembles E. serrata and E. sheldoni from which it is distinguished because the superior appendages are not tapered in distal half and also have a small excision apically.

Description. Head, body and wings brown; wings similar to E. merki ( Fig. 172 View FIGURES 168–174 ). Forewing length about 2.9–3.2 times width: male 3.3–3.6 mm, female 3.8 mm. Forewing fork 2 relatively long, sessile, length about 1.4–1.5 times length of fork 3; fork 3 relatively short, with long footstalk, length fork about 2.5–4.6 times length footstalk, footstalk length about 1.2–1.6 times length cross-vein m, r-m and m nearly contiguous at footstalk fork 3, r-m and m separated by about 0.4–0.8 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 3.3 times width, fork 2 sessile, length about 1.6–1.7 times length of fork 3.

Male Tergum X membranous, with one pair of robust dorsal processes, relatively widely separated, slightly crenulated meso-distally, about two thirds length of superior appendages ( Fig. 164 View FIGURES 162–167 ). Superior appendages in lateral view, length about 4 times width, not tapered distally, with small apical excision ( Fig. 162 View FIGURES 162–167 ); in dorsal view, length about 5 times width, with one pair of long mesal spines and several pairs of shorter spines distally ( Fig. 164 View FIGURES 162–167 ). Phallus simple, tube-like, robust ( Fig. 162 View FIGURES 162–167 ). Inferior appendages short; in ventral view, length about half width, fused in basal half, dilated and truncated distally, with small oval excision meso-distally ( Fig. 163 View FIGURES 162–167 ); in lateral view, slender, slightly curved, length about 5 times width ( Fig. 162 View FIGURES 162–167 ).

Female. Genitalia with a single, elongate, slender mesal process on sternite VIII, with a pair of small semicircular structures at base; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender ( Fig. 193 View FIGURES 184–195 ).

Etymology. Gippslandica - named for the type locality (East Gippsland, Victoria).
