Figs 29, 30 , 43

Holotype ♂, ANIC 040813 , Australia, Queensland, The Boulders, Babinda , 10-v-1967, D. H. Colless; specimen dry, pinned, terminalia preserved (glycerol) in microvial on the pin.

Description ♂ (♀ unknown).

Head: including rostrum, palp, scape and pedicel dark brownish grey, antennal flagellum slightly paler, side of vertex greyish yellow to dull orange.

Thorax: Pronotum pale yellowish brown. Remainder with scutum dark greyish to blackish brown, scutellum, mediotergite, laterotergite and pleura greyish brown. Legs with coxae and trochanter yellowish brown, femur greyish yellow, tibia, tarsus and claws greyish brown. Wing base and halter greyish yellow, remainder of wing suffused with pale grey.

Abdomen: greyish brown.

Terminalia ( Figs 29, 30 ): Gonocoxites only about half as long as gonostyli; gonostyli with tooth-shaped mesal lobe at about mid-length, with bird-head-shaped mesally directed apex and with a dorsomesal, trifid basal structure that appears bifid from most aspects as the middle lobe is very small and between the two other lobes; aedeagus with apical portion simple and very thin; aedeagal guide widely triangular; epandrium not covering base of gonocoxites.

Dimensions: Wing length 3.5 mm.

Etymology. Bonelya is from one of Australia’s Aboriginal languages and is a word for “bat”; a noun in apposition to

the generic name alluding to small, crepuscular, flight.

Discussion. The differences between male Ozeoura bonelya sp. nov., O. billeang sp. nov. and O. lottheggi sp. nov. are described above, under O. billeang . The most useful diagnostic characters of O. bonelya are the apically birdhead-shaped gonostyli with mesal tooth and trifid dorsomesal basal structure and the subtrianglar aedeagal guide. Ozeoura bonelya is known only from the type locality, The Boulders, Babinda, in tropical northeastern Queensland.
