Description
. Male c.
17 mm
long,
H
= 1.4 mm. In alcohol, well-coloured specimens under low magnification pale brown in body colour with dispersed brown speckling on metatergites`. Antennae moderately long (
Fig. 69
tar), about 1.75X a socket diameter apart.
Paranota
wide,
R
= 1.6, lateral edge parallel to body axis, 2-3 inconspicuous posterior marginal teeth (
Fig. 70
tar), posterior corners not turned up. Legs robust, tarsus considerably longer than femur, tibia with prominent ventral distal swelling (
Fig. 71
tar). Telopodite (
Figs 65
,
66
) reaching leg 6 when retracted.
Solenomere arising at half the telopodite height, directed distally, terminating at just over half the prefemoral process height, a rod-like, apically toothed, anteriorly directed projection arising at half the solenomere length on its anterior surface.
Tibiotarsus rod-like, pointed, directed posterodistally at small angle to telopodite axis, narrower than solenomere and about half as long. Femoral process arising at level of solenomere origin, blade-like, tapering, bluntly pointed, directed distally, not pressed close to prefemoral process, terminating at almost three-quarters the prefemoral process height (just distal to solenomere tip).
Prefemoral process at origin about half as wide as telopodite base, tapering strongly distally with simply pointed tip curving posteriorly.
Uncus prominent, arising on mesal side of prefemoral process at just over half the process height (just proximal to solenomere tip).
Distribution and habitat.
Known from wet eucalypt forest at three sites over a
10 km
section of the Strzelecki Ranges near Balook, in Gippsland (
Fig. 78
).
Etymology
. Named for Tarra-Bulga National Park, the apparent centre of the small known range of this species.
