Figs 111–113 View FIGURES 108–113 , 182 View FIGURES 175–183

Diagnosis. Ecnomina rostrata   is separated from others in the genus by the robust ventro-distal processes on the superior appendages, visible in dorsal and lateral view.

Description. Head, body and wings light brown; wings similar to E. legula   ( Fig. 3 View FIGURES 1–6 ). Forewing length about 2.8 times width: male 5.8 mm, female 7.0 mm. Forewing fork 2 relatively long, sessile, length about 1.1–1.2 times length of fork 3; fork 3 relatively long, sessile, cross-veins r-m and m not contiguous at fork 3 by about 1.0–1.4 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 2.6 times width, fork 2 sessile, length about 1.6 times length of fork 3.

Male. Tergum X membranous, short ( Fig. 113 View FIGURES 108–113 ). Superior appendages with robust ‘beak-like’ ventro-distal processes visible in lateral and dorsal views; in lateral view, length about twice width ( Fig. 111 View FIGURES 108–113 ); in dorsal view, robust, relatively broad in basal two thirds, length about twice width ( Fig. 113 View FIGURES 108–113 ). Phallus generally tubelike; in lateral view relatively slender ( Fig. 111 View FIGURES 108–113 ). Inferior appendages longer than superior appendages, dorsoventrally flattened; in ventral view, length about 1.1 times width, fused in basal two-thirds, rounded lateral margins, distal one-third separated narrowly by a mesal split ( Fig. 112 View FIGURES 108–113 ); in lateral view, robust, sub rectangular, length about 3 times width ( Fig. 111 View FIGURES 108–113 ).

Female. Genitalia with a single relatively elongate and slender mesal process on sternite VIII; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender ( Fig. 182 View FIGURES 175–183 ).

Holotype male: (specimen CT-451 figured), Queensland, Coomera Ck, Lamington Nat. Park (about 28°10'S, 153°12'E), 8 Feb 1961, Perkins ( NMV, T-19714). GoogleMaps  

Paratype: Queensland. 1 female (specimen CT-497 figured), collected with holotype ( NMV) GoogleMaps   .

Etymology. Rostrata - Latin word meaning beaked or curved (superior appendages).

Remarks. Only one male and one female specimen of Ecnomina rostrata   have been collected from the type locality in south-eastern Queensland (latitude 28°10'S).
