In BOLD Bin: BOLD:ACQ5133
A large species with the anterior tarsi of the male strongly bearded.
The type male was measured by Dr. P. Freeman of the British Museum of Natural History and later examined by me (see figure of hypopygium above).
Female:
Coloration essentially as in male, although generally darker, especially on the abdomen.
Wing length about 6.29 (4.72-7.36 mm; width about 1.64 (1.24-2.00) mm; VR 0.95 (0.91-0.99). About 28.8 (12-49) setae in squamal fringe (low values from Victorian specimens), in up to three rows, and 5.9 (4-8) SCf on brachiolum. LR about 1.37, higher in N.S.W. populations.
Relative lengths of antennal segments (micron)(% of neck in brackets): 229 (29) : 132 (44) : 146 (44) : 146 (49) : 306; AR 0.46 (0.41-0.53); A5/A1 1.35 (1.21-1.51). Cephalic tubules present but variable, 19-58 µm long, larger in Victorian populations, and about 1.3-3.8 times longer than width at base, seta usually lost. Clypeus about 1.7-2.2 times the diameter of the antennal pedicel; about 41.8 (30-54) clypeal setae. Palpal proportions (micron): 89 : 80 : 251 : 286 : 475; P5/P4 1.61 (1.48-2.01), P5/P3 1.83 (1.16-2.74).
Thoracic setae: Acrostichals Ð up to about 18; Humerals - 7 (4-10) mostly linear but small groups of 2-3; Dorsocentrals Ð 23 (17-27), DC+Hum - 30.6 (23-45); prealar 6.7 (5-8); supraalar usually 1; Scutellar in multiple rows, 16-30 in anterior rows, 19-22 in posterior row (total 38.6 (31-50).
Legs greenish, with tips and bases of femora and tibiae and tips of tarsi brown
Leg lengths and proportions (micron):
BR about 0.4-2.7. CS: Mid Ta1 59-81; Hind Ta1 70-101
MidTi/AntTi - 1.03-1.08
Morphologically very similar to C. occidentalis and C. duplex, but is distributed allopatrically to the former and differs from the latter by the generally shorter length of the mid and hind femur and tibia. As well C. australis tends to have less setae, particularly on the clypeus (35.1 cf. 39.4), GcIX (3-5 cf. 4-16) and segment X (17-32 cf. 28-42), while the ratio of fore Ta4/Ti in C. australis (0.50-0.56) appears to be greater than in both C. duplex (0.38-0.53) and C. occidentalis (0.39-0.42).
