Figures 182–185 ; Map 19

TYPES: Male holotype and female allotype collected during watering at Barr Creek, Cohuna , 358509S, 1448119E, Victoria (Apr. 18, 1998; J. Hooper, CVIC 506 ), deposited in NMV courtesy of J. Shield .

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

DIAGNOSIS: This distinctive species is unlikely to be confused with any other member of the genus; males have a long, dorsally situated and obliquely directed retrolateral tibial apophysis with its ventral surface abruptly narrowed below the tip (fig. 183), and females have a peculiar epigynum bearing a pair of hooded pockets posteriorly (fig. 184).

MALE: Total length 6.7. Abdominal dorsum with markings subdued gray rather than white, anterior femora darkened proximally. Palpal femur darkened on proximal half, distal half narrowed, twisted relative to proximal half; retrolateral tibial apophysis shifted dorsally, expanded behind tip (fig. 183); embolar tip long, strong, arched (fig. 182).

FEMALE: Total length 8.8. Coloration as in male. Epigynum with pair of posteriorly situated pockets bearing anterior hoods (fig. 184); spermathecae situated on internal projections of pockets (fig. 185).
