description: <i>Austrotinodes varus</i> sp. nov. Figs 4–7, 37 <b>Diagnosis.</b> This is a similar species to <i>A. doota</i>, with large, fused inferior appendages and superior appendages bifid or forked. This species is separated on the sub-equal forks on the superior appendages and the sub-ovoid shape of the inferior appendages, with length about 1.5 times width. <b>Description.</b> Head, body and wings brown, abdomen paler ventrally; wings partly figured (Fig. 4). Forewing length about 3.3 times width: male 4.5–5.3 mm, female 4.6 mm. Forewing fork 2 long, with short footstalk (sessile in female), footstalk between 0.3–1 times length of cross-vein r-m, length fork about 1.2–1.4 times length fork 3; fork 3 long, length fork about 1.7–2.7 times length footstalk, footstalk length about 2.1–3.0 times length cross-vein m. Hindwing length about 3.0–3.3 times width, fork 2 with footstalk relatively short, length footstalk about 0.5–0.9 times length cross-vein r-m, fork 2 about 1.0–1.2 times length of fork 3. Male. Tergum X membranous (Fig. 7). Superior appendages in lateral view, robust, broad, length about 1.5 times width, forked with robust, sub-equal ventral branch with a pair of dorso-mesally directed processes at base of superior appendages (Fig. 5); in dorsal view, length about 3 times width, apices slightly incurved (Fig. 7). Phallus simple, tube-like, with several long embedded spines; with a single sword-like process (phallic guide) arising from near the base of the inferior appendages (Fig. 5). Inferior appendages fused, dorso-ventrally flattened, robust; in ventral view, length about 1.5 times width, sub-ovoid, broadest near the middle, rounded laterally, narrowed subapically, with expanded apex (Fig. 6); in lateral view, length about 3 times width, broadest near the middle, narrowed in apical third, with dorsally directed apex (Fig. 5). Female. Female genitalia with a pair of elongate lobes which converge distally and a central pointed process on sternite VIII, segment IX relatively long, tapered slightly distally, segment X relatively very short with pair of cerci and papillae on segment XI; segments IX and X have scattered pairs of ‘spiny-hairs’ (Fig. 37). <b>Holotype male</b>: Queensland, Echo Ck, Mt Spec State Forest, 700m, 18°57'S, 146°10'E, lt tr., 16 Jan 1994, A.L. Sheldon (NMV, T- 20349). <b>Paratypes</b>: Queensland. 1 male, Birthday Ck, WNN Paluma, 18°58'S, 146°10'E, at light, 23 Dec 1989, R. St Clair; 1 female, same locality and collector, 17 Feb 1990; 1 female, same locality and collector, 26 Feb 1989; 1 male (specimen PT-1650 figured), Yuccabine Ck, Kirrama State Forest, 18°12'S, 145°45'E, 2 Jan–5 Mar 1985, R. Pearson and L. Benson; 1 male, Bellenden Ker Range, Cableway base station, 100m, 17–24 Oct 1981, Earthwatch / QM; 3 females (specimen CT-494 figured), collected with holotype (NMV). <b>Etymology.</b> <i>Varus</i> - Latin, word bent, grown inwards (superior appendages). <b>Remarks.</b> <i>Austrotinodes varus</i> is an uncommon species recorded from four localities in north-eastern Queensland (latitudinal range 17°16'– 18°58'S).
