Figures 482–485 ; Map 55

TYPE: Female holotype taken in pitfall trap in Sherbrook Forest Reserve , 378539S, 1458219E, Victoria (Apr. 10, 1978; M. Gray), deposited in AMS ( KS45345 ) .

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 tentatively matched here on the basis of similarities in size and coloration. Males can easily be recognized by their triangular retrolateral tibial apophysis (fig. 483) and sharply pointed conductor (fig. 482), females by the short, weak lateral epigynal margins (fig. 484).

MALE: Total length 5.8. Coloration as in C. keira except abdominal dorsum with hint of anterior transverse white stripe and leg femora darkened. Leg spination: femur III p0­1­1; tibia IV p0­1­1. Retrolateral tibial apophysis expanded at base, triangular, bifid at tip (fig. 483); embolar apophysis short, small, tegular apophysis with narrow apical projection, median apophysis sharply angled (fig. 482).

FEMALE: Total length 6.2. Coloration as in male. Leg spination: femur III p0­1­0, r0­1­ 0; tibiae: III r0­1­1; IV p0­1­1; metatarsi: III p0­1­1, r0­1­1; IV p0­1­1, v2­0­1p, r0­1­1. Epigynum with tiny anterior hood, lateral margins restricted to posterior half of epigynum (fig. 484); ducts tightly coiled posteriorly (fig. 485).
