DIAGNOSIS: Nearly identical in coloration to A. schwartzi and A. minutus except for completely dark brown hemelytron with a weakly transparent area in corium along medial portion of claval sutures (pl. 2). Recognized by apically gold coxae, shape of left paramere and phallotheca, and intermediate size between A. schwartzi and A. minutus . Female nearly identical in coloration to females of A. schwartzi and A. minutus .

DESCRIPTION: Male: Macropterous, medium sized, elongate, and parallel sided. Total length 3.22–3.55, width pronotum 0.90–0.94, maximum width across hemelytra 1.09–1.18. COLORATION: Dark brown, with weakly transparent area in corium along medial portion of claval sutures (pl. 2), and anterior margins of cuneus white. Head dark brown. All antennal segments brown, with segment 2 shade darker brown. Labium dark brown. Eyes dark red to purple. Thorax, pronotum, and scutellum dark brown. Thoracic pleura dark brown, Dorsolateral margin of metepisternum and scent gland with thin white margin. All coxae entirely dark brown with apical lightening to gold at joint with trochanter. Profemora dark basally, gold distally, meso- and metafemora completely dark brown. Pro- and mesotibiae segments brown basally, gold distally, metatibia are completely dark brown and with parallel rows of dark spicules. All tarsomeres are dark brown. Hemelytra dark brown, with weakly transparent area in corium along medial portion of claval sutures, at most J area of cuneus along anterior margin of cuneal fracture distinctly white with reddish tinge along anterior margins with cuneal fracture. Abdomen dark brown. STRUC- TURE: Vertex width narrower than width of one eye, eyes nearly total height of head when head viewed laterally. Length of antennal segment 2 1.33 total head width. GENITA- LIA: Phallotheca: L-shaped, relatively narrow with apex gently tapering toward twisted point (fig. 10C) Left Paramere: Posterior process relatively short and closer in size to anterior process, apex of posterior process directed ventrally (fig. 10B).

Female: Macropterous. Total length 2.67– 3.07, width pronotum 0.87–0.95, width at widest part of hemelytra 1.14–1.24. STRUC- TURE: Vertex nearly takes up half total head width. Length antennal segment 2 1.2 times total head width. COLORATION: Hemelytron darker in than in male, transverse fascia much more pronounced with anterior of corium completely white with fascia and with anterior margin transitioning from gold brown into dark brown rather than relatively defined line in male (pl. 2), profemur darker with apical lightening to gold at joint with protibia less pronounced, dorsoposterior margin of metepisternum with wider white margin, and cuneus with larger lobes white.

ETYMOLOGY: Named for the collecting site of Bournda National Park in New South Wales. Noun in apposition.

HOSTS: Myrtaceae , specifically Melaleuca processillaris (Sol. Ex Gaertn.) and Kunzea ambigua (Sm.) .

DISTRIBUTION: New South Wales.

DISCUSSION: The coloration in this species is very similar to A. minutus and A. schwartzi . All three species have the anterior process of the left paramere relatively short compared to the remaining Ausejanus species. However, the subtle differences in coloration in the males, the angle of the apex of the posterior process of the left paramere, and the structure of the phallotheca clearly indicate they are separate species.
