Diagnosis. Daternomina loowa   can be distinguished from closely related Daternomina species   , D. trulla   and D. quasitrulla   , by having truncate superior appendages and fused, short inferior appendages with relatively shallow notch apically, dividing at most the distal third.

Description. Head, body and wings brown; wings similar to D. irrorata   ( Fig. 1 View FIGURES 1–6 ). Forewing length about 2.8–3.0 times width: male 4.4 mm, female 4.6 mm. Forewing fork 2 relatively long, sessile, length about 1.7 times length of fork 3, nygma present; fork 3 relatively long, length about 2.3–2.5 times length footstalk, footstalk length about 1.5–1.7 times length cross-vein m; r-m and m displaced at fork 3 by about 1.8 times length cross-vein m; fork 4 length similar to fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 3 times width, fork 2 sessile, length about 1.5 times length of fork 3.

Male. Tergum X membranous with a pair of small disto-mesal processes ( Fig. 27 View FIGURES 25–30 ). Superior appendages strongly laterally compressed; in lateral view, broad, truncate distally, length about 2.5 times width ( Fig. 25 View FIGURES 25–30 ); in dorsal view, relatively slender, length about 5 times width, with a group of spines on inner surface ( Fig. 27 View FIGURES 25–30 ). Phallus generally tube-like, with a pair of long embedded spines; with a pair of slender, curved processes (phallic guides) arising from near the base of the inferior appendages ( Fig. 25 View FIGURES 25–30 ). Inferior appendages small, fused, strongly dorso-ventrally compressed; in ventral view, short, rounded laterally, with a shallow, wide Vshaped notch distally ( Fig. 26 View FIGURES 25–30 ); in lateral view, relatively short and robust ( Fig. 25 View FIGURES 25–30 ).

Female. Genitalia with a pair of large, narrowly separated ‘tongue-shaped’ lobes on sternite VIII, with characteristic ‘small dark triangle’ visible mesally ( Fig. 58 View FIGURES 55–62 ).

Holotype male: Queensland, Seary’s Ck, Rainbow Beach , 25º58'S, 153º04'E, 9 Jan 1986, G. Theischinger ( NMV, T-19572, specimen CT-457 figured). GoogleMaps  

Paratypes: Queensland. 4 females (specimen CT-493 figured), collected with holotype GoogleMaps   ; 7 females, same loc. and coll., 6 Dec 1984 ( NMV)   .

Other material examined: Queensland. 3 females, same loc. and coll. as holotype, 9 Feb 1987   ; 1 female, Blue Lake , N Stradbroke Isl., 27 May 1973   , H. Burton; 1 female, Myora Springs, N Stradbroke Isl. , 3 Sep 1974   , A. Bensink; 1 female, same loc., 22 Mar 1969, J. Attwood; 1 female, Dunwich (N Stradbroke Isl. ), 4 May 1969   , lt tr., M. Cox.

Etymology. Loowa - northern Australian Aboriginal word for rainbow (type locality-Rainbow Beach).

Remarks. One male of Daternomina loowa   has been collected from the type locality in south-eastern Queensland, plus females from several localities including North Stradbroke Island (latitudinal range 25º58'- 27º32'S).
