Baeoura hemmingseni Alexander, 1978: 168 View in CoL .

Material examined. Holotype ♂: Australia, Atherton ( AC); (slide of wing, see Fig. 20 View Figures 20–22 ); parts of holotype supposedly deposited in ANIC were not found; 1 paratype ♂ (slide of terminalia, see Fig. 22 View Figures 20–22 ).

From the original description of Baeoura hemmingseni Alexander, 1978 . Venation: “Sc1 relatively short, nearly one-half Rs; R 2+3+4 suberect, R 5 in direct alignment with Rs; vein 2nd A long” ( Fig. 20 View Figures 20–22 ). “Hypopygium with the apparent tergite, t, a subquadrate yellow structure, posterior margin bilobed, with shallow median emargination;

surface of plate with abundant short erect setae. Dististyle, d, distinctive (shown in two aspects in figure); a simple structure, basal two-thirds more expanded, bearing a shortclavate dusky more basal lobe provided with scattered erect slender setae and a paler subapical more slender lobe with six long stout yellow setae; apical third of style narrowed into a long straight darkened rod, apex obtuse, without setae. Phallosome, p, about as shown, narrowed outwardly, the enclosed darkened aedeagus, a, short and stout, strongly coiled basally” ( Figs 21, 22 View Figures 20–22 ).

Discussion. Differences between males of Ozeoura convoluta , O. hemmingseni , O. tasmanica and O. tonnoiri are described above, under O. convoluta . The characters most useful for the identification of male O. hemmingseni are the massive bilobed aedeagal guide together with the elongate differentiated gonostyli. In the original descriptionAlexander (1978) describes the gonostylus as bearing a short-clavate dusky more basal lobe, but two basal lobes can be detected in the paratype slide. Ozeoura hemmingseni is known only from the type locality, Atherton in tropical Queensland.
