Figs 11–13

Diagnosis. Austrotinodes theischingeri is placed in a group with Austrotinodes varus , A. doota and A. bifurcatus based on the superior appendages, forked or with long baso-ventral process and the fused, broad inferior appendages. It is distinguished mainly by small differences in the shape of the superior appendages which are slender, narrow basally.

Description. Head, body and wings brown; wings similar to A. varus ( Fig. 4 ). Forewing length about 2.7–2.9 times width: male 4.4–4.7 mm. Forewing fork 2 long, with footstalk, footstalk about 0.8–1.0 times length of cross-vein r-m, length fork about 1.2 times length fork 3; fork 3 long, length fork about 2.0–2.3 times length footstalk, footstalk length about 2.3–2.5 times length cross-vein m. Hindwing length about 2.7 times width, fork 2 with footstalk short, footstalk length about 0.8–1.0 times length cross-vein r-m, fork 2 about same length as fork 3.

Male. Tergum X membranous with a pair of slender, straight processes apically ( Fig. 13 ). Superior appendages in lateral view, slender, length about 4.5 times width, narrow basally, with long, slender basoventral process ( Fig. 11 ); in dorsal view, relatively slender, length about 5 times width, apices slightly incurved ( Fig. 13 ). Phallus generally tube-like, truncated apically; with a single sword-like process (phallic guide) arising from near the base of the inferior appendages ( Fig. 11 ). Inferior appendages fused, strongly dorso-ventrally flattened; in ventral view, length about same as width, very broad and rounded laterally near the middle, narrowed subapically, with rounded apex ( Fig. 12 ); in lateral view, broadest near middle, tapered apically ( Fig. 13 ).

Female. Unknown.
