Figs 84–86 View FIGURES 84–89

Diagnosis. Ecnomina attunga   closely resembles the other five species in this group, especially E. boogoo   , but it is distinguished by inferior appendages with relatively short and meso-distally directed digitiform projection, lateral processes of segment IX with only one relatively long and robust spine subapically and superior appendages in lateral view, not relatively broad in apical third.

Description. Head, body and wings light brown; wings similar to E. legula   ( Fig. 3 View FIGURES 1–6 ). Forewing length about 3 times width: male 5.2–5.4 mm. Forewing fork 2 relatively long, sessile, length about 1.1–1.3 times length of fork 3; fork 3 relatively long, with short footstalk, length fork greater than 5.4 times length footstalk, footstalk length about 0.9–1.1 times length cross-vein m, r-m and m not contiguous at fork 3 by about 0.8 times length cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about 1.9 times length of fork 4. Hindwing length about 3 times width, fork 2 sessile, length about 1.5 times length of fork 3.

Male. Segment IX with a pair of long lateral processes with one ventrally directed, relatively long bristle or spine subapically. Tergum X membranous ( Fig. 86 View FIGURES 84–89 ). Superior appendages in lateral view, length about 3.5 times width, narrowed in apical third ( Fig. 84 View FIGURES 84–89 ); in dorsal view, fused in basal half, relatively slender in distal third, apices narrowly separated ( Fig. 86 View FIGURES 84–89 ); with one pair of stout spines baso-ventral to base of superior appendages. Phallus generally tube-like, slender, slightly dilated distally ( Fig. 84 View FIGURES 84–89 ). Inferior appendages in ventral view, fused basally, narrowly separated in distal half, short meso-distally pointed apices ( Fig. 85 View FIGURES 84–89 ); in lateral view, length about twice width, sub-ovate with short pointed apices ( Fig. 84 View FIGURES 84–89 ).

Female. Unknown.

Holotype male: Victoria, Pretty Valley Ck d/s pond (about 36°52'S, 147°17'E), 10 Jan 1980, D. Cartwright ( NMV, T-19674). GoogleMaps  

Paratype: New South Wales. 1 male (specimen CT-546 figured), Leatherbarrel Ck, Kosciusko Nat. Pk, 5 Jan 1984, G. Theischinger   .

Etymology. Attunga - New South Wales Aboriginal word for high place (relatively high altitude habitat).

Remarks. Ecnomina attunga   has been collected from only two localities in south-eastern New South Wales and north-eastern Victoria (latitudinal range 36°28'- 36°52'S).
