Austrotinodes varus -group

Wings similar to A. varus ( Fig. 4 View FIGURES 1–7 ), forewing length about 2.7–3.3 times width: male 4.3–5.4 mm, female 4.6 mm. Forewing fork 2 relatively long, usually with footstalk, footstalk ranges from 0–1.5 times length of crossvein r-m, length fork about 0.9–1.4 times length fork 3; fork 3 length from 1.7–3.6 times length footstalk, footstalk length about 1.6–3.0 times length cross-vein m; thyridial cell relatively short, cross-vein basal to conjoin of forks 3 and 4. Hindwing length about 2.7–3.3 times width, fork 2 with footstalk relatively short, length footstalk about 0.5–1.3 times length cross-vein r-m, fork about 0.9–1.2 times length of fork 3; discoidal cell narrow, length about 4 times width; with two long and one shorter anal veins.

Males with inferior appendage single or fused, large, broadened near middle, with central apex and with superior appendages forked or with long baso-ventral process. Only the female of A. varus is known in this group. It has a pair of elongate lobes and a central pointed process on sternite VIII ( Fig. 37 View FIGURES 37–40 ).

There are four species in the group- A. doota , A. varus , A. bifurcatus and A. theischingeri , all from eastern Queensland. The varus group probably have the most similarities with some of the Chilean species of Austrotinodes , e.g. superior appendages with elongate ventro-basal process, inferior appendages fused and large.
