Diagnosis. Ecnomina lamingtonensis can be separated from all other species in the genus by the distinctive superior appendages, which are slender and upturned in the distal third.

Description. Head, body and wings light brown; wings similar to E. scutica ( Fig. 5 ) and E. legula ( Fig. 3 ). Forewing length about 2.8 times width: male 6.0– 6.2 mm. Forewing fork 2 relatively long, sessile, nygma present, length about 1.1–1.2 times length of fork 3; fork 3 relatively long, with very short footstalk, length fork at least ten times length footstalk, footstalk length 0.2–0.3 times length cross-vein m, r-m and m not contiguous at fork 3 by about 1.5 times length cross-vein m; fork 4 present, similar length to fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 2.7 times width, fork 2 sessile, length about 1.2–1.3 times length of fork 3.

Male. Tergum X membranous, with two slender upturned processes disto-laterally. Superior appendages broad basally, slender and upturned in distal third ( Figs 66, 68 ). Phallus generally tube-like; with a single, robust, slightly curved robust process (phallic guide) arising from near the base of the inferior appendages ( Fig. 66 ). Inferior appendages dorso-ventrally compressed; in ventral view, fused, broad, sub quadrate, length about 0.7 times width, with a small central notch distally ( Fig. 67 ); in lateral view, robust, rounded distally ( Fig. 66 ).

Female. Unknown.

Holotype male: Queensland, Coomera Ck, Lamington Nat Park (about 27°58'S, 153°13'E), 8 Feb 1961, Perkins ( NMV, T-19668).

Paratype: Queensland. 1 male, collected with holotype (specimen CT-483 figured) ( NMV) .

Etymology. Lamingtonensis - named for the type locality (Lamington Nat. Park).

Remarks. Two male specimens of Ecnomina lamingtonensis have been collected from the type locality in south-eastern Queensland (latitude 27°58'S).
