description: <i>Austrotinodes yalga</i> sp. nov. Figs 14, 15, 22–24, 39 <b>Diagnosis.</b> <i>Austrotinodes yalga</i> can be distinguished from the nearest group member <i>A. glaya</i> in possessing paired inferior appendages with length less than width. <b>Description.</b> Head, body and wings brown; wings shown in Fig. 14. 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). Superior appendages in lateral view, broad, tapered gradually in apical half, with short ventro-mesal process with group of four long spines (Fig. 22); in dorsal view, short, robust, length about 3 times width, with small subapical mesal process, extensive membranous area mesal to superior appendages (Fig. 24). Phallus generally tube-like, with dorsal process (Fig. 22); 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); in lateral view, length about same as width, very broad and rounded laterally near the middle, narrowed subapically (Fig. 22). 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). <b>Holotype male</b>: Victoria, Little R., 3 km SE Taggerty (about 37°20'S, 145°43'E), 6 Jan 1972, A.Neboiss (NMV, T- 20364). <b>Paratypes</b>: Victoria. 1 male (specimen CT-432 figured), 4 females (specimen CT-488 figured), collected with holotype; 1 male, Watts R., Fernshaw, 12 km NE Healesville, 11 Feb 1982, Neboiss and Walker; 1 male, Tennyson Ck, 5 km NW Buldah, 37°14'S, 149°07'E, 1–7 Jan 1982, Anzses Exped.
