TYPE: Male holotype taken in drift fence pitfall trap 20.4 km N Millawa South Bore , 348359S, 1418039E, Victoria (Feb. 1987; A. Yen), deposited in NMVS .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: This eastern sister species of B. zuytdorp can easily be distinguished by the much narrower median apophysis of males (fig. 530) and the posteriorly narrower epigynum of females (fig. 532).

MALE: Total length 6.1. Coloration as in B. zuytdorp except femora not darkened, all legs orange. Leg spination: tibiae IV v1p­1p­ 2; metatarsi III v2­0­2. Retrolateral tibial apophysis angular (fig. 531), median apophysis relatively narrow (fig. 530).

FEMALE: Total length 7.3. Coloration as in male except abdominal dorsum with pair of paler patches anteriorly. Leg spination: tibiae IV v1p­1p­2; metatarsi III v2­0­2. Epigynal atrium not widened posteriorly (fig. 532); spermathecae extending far anterior of epigynal hood (fig. 533).
