Diagnosis. Austrotinodes yalga can be distinguished from the nearest group member A. glaya in possessing paired inferior appendages with length less than width.

Description. Head, body and wings brown; wings shown in Fig. 14 View FIGURES 8–15 . Forewing length about 3.0–3.3 times width: male 4.5–5.2 mm, female 5.7–6.0 mm. Forewing fork 2 long, with footstalk, footstalk length varies from 1.0–2.3 times length of cross-vein r-m, length fork about same length as fork 3; fork 3 long, length about 1.4–2.9 times length footstalk, footstalk length about 2.0–3.0 times length cross-vein m. Hindwing length about 3 times width; fork 2 length about 0.8–0.9 times length of fork 3, with long footstalk, footstalk length about 2.2–3.1 times length cross-vein r-m,.

Male. Tergum X membranous with a pair of small disto-mesal processes ( Fig. 24 View FIGURES 16–24 ). Superior appendages in lateral view, broad, tapered gradually in apical half, with short ventro-mesal process with group of four long spines ( Fig. 22 View FIGURES 16–24 ); in dorsal view, short, robust, length about 3 times width, with small subapical mesal process, extensive membranous area mesal to superior appendages ( Fig. 24 View FIGURES 16–24 ). Phallus generally tube-like, with dorsal process ( Fig. 22 View FIGURES 16–24 ); with a dark, robust bifid process (phallic guide) arising from near the base of the inferior appendages. Inferior appendages in ventral view, small, paired processes, length less than width, bases widely separated ( Fig. 23 View FIGURES 16–24 ); in lateral view, length about same as width, very broad and rounded laterally near the middle, narrowed subapically ( Fig. 22 View FIGURES 16–24 ).

Female. Female genitalia with a pair of sub-quadrate lobes with small processes disto-mesally and distolaterally; segment IX relatively long tapered slightly distally, segment XI relatively very short with pairs of cerci and papillae; segments IX and X have scattered pairs of ‘spiny-hairs’ ( Fig. 39 View FIGURES 37–40 ).
