Description
. Male c.
17 mm
long,
H
= 1.5 mm. In alcohol, well-coloured specimens under low magnification with very pale brown body colour and red speckling on metatergites, more intense medially and in a transverse band close to posterior metatergal margin. Antenna short, stout (
Fig. 69
mac).
Paranota
fairly wide,
R
= 1.5, with several indistinct posterior marginal teeth (
Fig. 70
mac), posterior corners not turned up. Legs short, robust, tarsus about as long as femur, tibia with slight ventral distal swelling (
Fig. 71
mac). Telopodite (
Figs 47
,
48
) reaching leg 5 when retracted. Solenomere arising at one-third to half the telopodite height, directed posterodistally at c. 45° to telopodite axis, terminating with small, pointed subapical projection at one-quarter to one-third the prefemoral process height. Tibiotarsus strongly flattened anteroposteriorly, about as long as solenomere but diverging from it slightly, the expanded tip curling back anterodistally. Femoral process arising distal to solenomere origin at about one-quarter the prefemoral process height, blade-like, wide, pressed close to prefemoral process at base, deeply notched distally with rounded tips, terminating at just under half the height of prefemoral process.
Prefemoral process at its origin about half as wide as telopodite base, slightly tapered, curving posteromesally at about two-thirds its length, the lateral edge of the distal half a comb of c. 25 long, mainly basally directed teeth, the process tip turned back nearly 180°
. Uncus large, arising from mesal edge of prefemoral process at about one-third the process height (just distal to solenomere tip).
Distribution and habitat.
Known from wet eucalypt forest at two localities c.
30 km
apart: the upper slopes of Mt Macedon, where it is abundant, and near Blakeville in the southern portion of the Wombat State Forest (
Fig. 79
).
Etymology
. Named for the
type
locality,
55 km
north-west of Melbourne.
