description: <i>Daternomina jacksonae</i> Neboiss Figures 10–12, 56 <i>Daternomina jacksonae</i> Neboiss, 2003: 66, figs 17A–E. Diagnosis. <i>Daternomina jacksonae</i> can be distinguished from all other <i>Daternomina</i> species by having inferior appendages which are small, paired, broad-based, tapering and upturned distally mesally. Description. (Revised after Neboiss 2003). Head, body and wings brown; wings (Neboiss 2003, fig. 17E) similar to <i>D. irrorata</i> (Fig. 1). Forewing length about 2.8–3.2 times width: male 4.1–4.9 mm, female 4.5–5.0 mm. Forewing fork 2 relatively long, sessile, about 1.7–2.1 times length of fork 3, nygma present; fork 3 relatively long, length fork 3 about 1.3–2.3 times length footstalk, footstalk length about 1.8–2.6 times length cross-vein m; r-m and m displaced at fork 3 by about 1.3–1.7 times length cross-vein m; fork 4 length similar to fork 3; fork 5 long, length about 1.8 times length of fork 4. Hindwing length about 3 times width, fork 2 sessile, length about 1.8–2.2 times length of fork 3. Male. Tergum X membranous (Fig. 12). Superior appendages strongly laterally compressed; in lateral view, broad, widened distally, length about 1.5 times width (Fig. 10); in dorsal view, relatively slender, length about 4 times width, with two subapical projections and a group of spines on inner surface (Fig. 12). Phallus slender, generally tube-like, with a pair of spines apically; with a pair of slender, curved processes (phallic guides) arising from near the base of the inferior appendages (Fig. 10). Inferior appendages small; in ventral view, paired, discrete, broad basally, tapering distally, separated narrowly by a mesal split (Fig. 11); in lateral view, slender and upturned (Fig. 10). Female. Genitalia with a pair of large relatively widely separated 'tongue-shaped' lobes on sternite VIII, with characteristic 'teardrop-shaped' internal structure visible mesally (Fig. 56).

Remarks. <i>Daternomina jacksonae</i> has been collected from Tasmania, eastern half of Victoria and six widely separated localities in eastern New South Wales (latitudinal range 28°53'- 42°58'S). Neboiss's (2003) figures have been redrawn to allow direct comparisons and to accompany the description that is revised in light of new interpretations of <i>Daternomina</i> genitalic structures. Some mainland Australian specimens have inferior appendages which are more elongate and slender distally (Fig. 11a).
