TYPE: Female holotype taken in pitfall trap 39 km E of Laverton, 28 ° 28 ̍ S, 122 ° 50 ̍ E, Western Australia (Oct. 23–25, 1990; E. Pianka), deposited in WAM (99/519) .

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

DIAGNOSIS: Males and females have not been collected together, but are matched here on the basis of their respective similarities to those of F. woodleigh .

Leg spination: femora III p1­1­0, r0­1­0; tibiae: III p0­0­0, r0­1­0; IV d1­1­0, p1­0­1; metatarsi: II v2­0­0; III p1­0­0, r1­0­ 0; IV p1­0­0, r1­2­0. Retrolateral tibial apophysis expanded distally (fig. 522); retrolateral edge of median apophysis unsclerotized (fig. 521).

FEMALE: Total length 10. Coloration as in male. Leg spination: femora: I p1­1­1, r0­1­ 1; II r0­1­0; III p1­1­0, r0­1­0; IV p1­1­0, r0­ 0­0; tibiae: III p1­0­0, r0­1­1; metatarsi: I v2­ 1p­0; II 2­2­0; III p0­1­0; IV p1­0­0.
