Austrotinodes theischingeri   sp. nov.

Figs 11–13 View FIGURES 8–15

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 View FIGURES 1–7 ). 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 View FIGURES 8–15 ). Superior appendages in lateral view, slender, length about 4.5 times width, narrow basally, with long, slender basoventral process ( Fig. 11 View FIGURES 8–15 ); in dorsal view, relatively slender, length about 5 times width, apices slightly incurved ( Fig. 13 View FIGURES 8–15 ). 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 View FIGURES 8–15 ). 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 View FIGURES 8–15 ); in lateral view, broadest near middle, tapered apically ( Fig. 13 View FIGURES 8–15 ).

Female. Unknown.
