Figs 31–33 View Figures 31–33 , 48 View Figures 38–50

Holotype ♂, ANIC 040814 View Materials , Australia, Queensland, -17.03° 145.12°, 3 km N by E of Mt Tip Tree , at light, 20-x-1980, D. H. Colless; specimen dry, pinned, terminalia preserved (glycerol) in microvial on the pin.

Description ♂ (♀ unknown).

Head: on top largely brownish yellow to medium brown; rostrum, palp and antenna medium to dark brown, side of vertex greyish yellow to dull orange.

Thorax: Pronotum greyish yellow. Remainder with scutum blackish brown, scutellum, mediotergite, laterotergite, pleura and meron greyish brown. Legs brownish yellow to yellowish brown, increasingly darker from coxa to tarsus. Wing base and halter brownish yellow, remainder of wing suffused with yellowish brown.

Abdomen: brown.

Terminalia ( Figs 31–33 View Figures 31–33 ): Gonocoxites short; the straight slender pointed gonostyli at least twice as long as gonocoxites and with four basal lobes of various shapes and sizes; aedeagus with apical portion very thin and apparently bifid; aedeagal guide rather narrow with triangular lobe each side and ending in two small subtriangular lobes; epandrium not covering base of gonocoxites.

Dimensions: Wing length 4.8 mm.

Etymology. Lottheggi 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 male O. lottheggi are the apically conical gonostyli with four basal lobes of various size and shape but without mesal tooth at about mid-length, and the rather narrow trapezoidal aedeagal guide. Ozeoura lottheggi is known only from the type locality, 3 km N by E of Mt Tip Tree, in tropical northeastern Queensland.

Holotype Dingo Tops Forest Park , 950 m, rainforest, malaise, 20 Feb.–23 Mar. 1993, G. Williams; specimen in 70% ethanol, therefore bleached, terminalia preserved (glycerol) in microvial in glassvial together with specimen . Paratype: 1♂ (terminalia missing), same data as holotype, AM K.421142.

Description ♂ (♀ unknown).

Head: including rostrum, palp and antenna yellow.

Thorax: Pronotum whitish yellow. Remainder yellow, slightly darkened to brownish at anterior face of prescutum. Legs whitish yellow. Wing and halter yellowish white.

Abdomen: yellowish white.

Terminalia ( Figs 34, 35 View Figures 34, 35 ): Gonocoxites short and ventrally completely fused; gonostyli about as long as gonocoxites, slim with apical third continuously narrowing, and basally with a medially directed, somewhat bowed lobe with apex rounded, darkened and setose; aedeagus convoluted, with apical portion simple and very thin; aedeagal guide largely parallel sided, distally bilobed.

Dimensions: Wing length 4.5 mm.

Etymology. Dingo after the type locality Dingo Tops Forest Park; it is treated as a noun in apposition to the generic name.

Discussion. Male Ozeoura dingo sp. nov. does not appear particularly close to any of the other Ozeoura species. It stands out from all of them by ventrally completely fused gonocoxites and two-armed gonostyli which at the present time seem to be the only available useful characters for its identification. Ozeoura dingo is known only from the type locality, Dingo Tops Forest Park in northeastern New South Wales, where it was found to coexist with O. tonnoiri .
