Daternomina genoaensis   sp. nov.

Figures 13–15 View FIGURES 13–18

Diagnosis. Daternomina genoaensis   can be distinguished from all other Daternomina species   by having short, mesally divided inferior appendages which in lateral view are not upturned distally.

Description. Head, body and wings brown; wings similar to D. irrorata   ( Fig. 1 View FIGURES 1–6 ). Forewing length about 3 times width: male 4.8 mm. Forewing fork 2 relatively long, sessile, about twice length of fork 3, nygma present; fork 3 relatively long, length about twice length footstalk, footstalk fork 3 length about 2.2 times length cross-vein m; r-m and m displaced at fork 3 by about 1.5 times length cross-vein m; fork 4 length similar to fork 3; fork 5 long, about 1.8 times length of fork 4. Hindwing length about 3 times width, fork 2 sessile, length about twice length of fork 3.

Male. Tergum X membranous with a pair of triangular lobes ( Fig. 15 View FIGURES 13–18 ). Superior appendages strongly laterally compressed; in lateral view, broad, widened slightly distally, length about 1.5 times width ( Fig. 13 View FIGURES 13–18 ); in dorsal view, relatively slender, length about 4.5 times width, with a triangular subapical projection and a group of spine-like setae on inner surface ( Fig. 15 View FIGURES 13–18 ). Phallus generally tube-like, laterally compressed, with a pair of small spines apically; with a pair of slender, curved processes (phallic guides) arising from near the base of the inferior appendages ( Fig. 13 View FIGURES 13–18 ). Inferior appendages short, robust; in ventral view, paired, fused basally, separated narrowly by a mesal split ( Fig. 14 View FIGURES 13–18 ); in lateral view not upturned distally ( Fig. 13 View FIGURES 13–18 ).

Female. Unknown.

Holotype male: (specimen CT-525 figured), Victoria, Genoa Ck, 4 km W of Genoa (about 37°28'S, 149°34'E), UV lt, 8 Dec 2003, D. Cartwright ( NMV, T-19564). GoogleMaps  

Other material examined: Victoria. 1 male, Yarra R., Reefton Rd, 1 Dec 2005, D. Cartwright   .

Etymology. Named after the Genoa Creek (type locality).
