Diagnosis. This species, known only from males, closely resembles that of B. dilatum , but is distinguished by the slightly smaller body, darker body, mesoscutal setate warts elongateovoid, and the sharp, pick-shaped form of the upper penis cover lobes in ventral view.

Description. Mesothorax with mesoscutellum shield shaped, without setate warts.

Male. Length of each forewing 9.0– 10.6 mm (n = 5). Small white area around lower part of wing at anastomosis. Sternite VII without median spur or tab. Genitalia: Pre-anal appendages stout, apically rounded in ventral view. Upper penis cover lobes produced distally, pick-shaped apicolaterally in ventral view, in lateral view triangular apico-dorsally. Inferior appendages each with coxopodite broad at base, in lateral view produced in slender, curved dorsal lobe bearing cluster of stubby black setae apically; harpago forming short apically truncate lobe bearing stout peg-like black setae at tip.

Female. Unknown.

Distribution. Collected from Cape York, Queensland, from the two sites to the north of Cairns and south of Cooktown.

Etymology. From the Latin dolabratus, meaning pick-shaped for the appearance of the upper penis cover lobes.
