Material examined. Holotype. male, Queensland, Goomburra State Forest , NE of Warwick, 28° 03'S 152° 07'E, 20.i.1986, G. Theischinger ( NMV TRI- 27112 ).

Paratypes. New South Wales: 1 male, 4 females, Styx River, Hyatt Flat, 8.xii.1998, G. Theischinger ( ANIC).

Diagnosis. Adults of this species closely resemble those of B. australicum in having a pair of setose warts on the mesoscutellum; the males of both species have a brush of short, blunt black setae terminally on each harpago and, in lateral view, the pre-anal appendages are broad-based and gradually tapered distally. The male of B. goomburra is characterised by having the inferior appendages narrower than those of B. australicum and the coxopodites lacking apicomesal clusters of setae that are present in B. australicum . The male of B. goomburra resembles that of B. costatum with the harpago bearing an elongate and narrow brush of stout black setae occupying almost its entire inner distal margin, but differs from B. costatum in that B. goomburra has a subcircular to rectangular mesoscutellum bearing small paired setate warts separate from each other and close to the posterior margin, whereas the mesoscutellum of B. costatum is ovoid and with large paired setate warts fused and covering most of the mesoscutellum.

Description. Mesothorax with mesoscutellum bearing pair of setate warts close to distal margin.

Male. Length of each forewing 6.5–7.2 mm (n = 2). Abdominal segment VII bearing stoutly rounded midventral tab. Genitalia: Pre-anal appendages in lateral view elongate triangular; upper penis cover in ventral view forming pair of short, stout, apically expanded structures; inferior appendages in ventral view each with coxopodite about equal width throughout length, without apicomesal brush of setae, harpago not clearly delineated, with somewhat stout, short, blunt black setae lining entire mesal side, giving toothbrush-like appearance.

Female. Length of each forewing 8.0– 9.6 mm (n = 4). Terminalia: Apical lobes broad-based, arising close to each other, then tapered to narrowly rounded apices.

Distribution. Collected from just north of the New South Wales – Queensland border, and from the Styx River in the Northern Tablelands area of New South Wales.

Remarks. No specimens recognisable as B. goomburra are among material for which molecular (CO1) data are available at present.

Etymology. Named for the holotype locality.
