Material examined. Holotype. male, Queensland, Montville, Bon Accord Falls, 27.ix.1955, A.N. Burns (NMV Tri-27064).

Paratypes. Queensland: 3 male, 1 female, Montville, Bon Accord Falls, 29.ix.1955 A. N. Burns (NMV TRI-27063); 1 male, same data (NMV Tri-27066); 1 male, south-east Queensland, Stony Creek, Conondale Range, 10.viii.1988, S. Bunn (NMV Tri-27120) .

Diagnosis. In most features, B. lobatum sp. nov. resembles B. lorien sp. nov. but alone among congeners, this species has the apicomesal angle of the otherwise subquadrate coxopodite of the inferior appendages produced and rounded distally; the pre-anal appendages are tapered distally, and a small rounded mesal process occurs on sternite VII. The female is indistinguishable from those of B. lorien, both having stepped (obliquely truncate) apical lobes.

Description. Thorax with mesoscutellum almost subquadrate, pale, margin dark, lacking setate warts.

Male. Length of each forewing 5.2–7.2 mm (n = 5). Sternite VII with small, apically rounded median tab. Genitalia: Pre-anal appendages stout in dorsal view, tapered to rounded apices, in lateral view almost same width throughout, apically rounded. Lobes of upper penis cover in ventral view constricted distally to form sharp tips, in lateral view stout, rounded apically. Inferior appendages each with coxopodite in ventral view stout, apicomesal angle slightly produced, rounded; harpago narrow near base, cluster of short, dark, bristle-like setae apically.

Female. Length of each forewing 8.6 mm (n = 1). Terminalia: Distal abdomen bearing pair of apical lobes, stout basally, narrowed laterally, and produced to rounded apex.

Distribution. Known only from north of Brisbane in the Sunshine Coast region of south-eastern Queensland.

Etymology. Named for the expanded apicomesal angles of the inferior appendages.
