Diagnosis. Distinguished from most other species of Barynema by having a pair of setate warts on the mesoscutellum, a feature shared with B. goomburra sp. nov., from which it differs by having male genitalia in ventral view with the coxopodite of each inferior appendage subquadrate, and in both ventral and lateral views the harpago with a short, slender basal portion before the swollen terminal section that bears a broader hairbrush-shaped area of short blunt black setae, rather than an elongate toothbrush-shaped region as in B. goomburra sp. nov.

Description. Male. Length of each forewing 6.4–7.8 mm (n = 10). Sternite VII bearing apically rounded median tab. Genitalia: see Mosely and Kimmins, 1953: 162).

Female. Length of each forewing 8.4–10 mm (n = 3). Terminalia: Apical lobes on abdominal segment X short, broad, almost quadrate.

Distribution. Found in north-east New South Wales, in the Barrington Tops-Wauchope and mid north coast regions.

Remarks. Two specimens among those that have been sequenced for the BOLD project can be referred to B. australicum . Each appears in a different cluster on the current BOLD Taxon Identification Tree. This is due to either contamination of the CO1 gene or the presence of sibling species. Several more specimens are required before this can be resolved. This species, together with specimens here referred to B. dilatum sp. nov., show no presently resolvable relationships.
