Notodascillus iviei sp. n.

(Figures 18–19, 24, 28, 44–50, 51)

Etymology. This new species is dedicated to Dr. Michael A. Ivie (Montana State University), acknowledging his knowledge of Dascillidae and support for the senior author in his doctoral research. Ivie was also the first person that recognized the third species of the Australian Notodascillus .

Diagnosis. Notodascillus iviei is most similar to N. brevicornis , sharing the anteriorly narrowing pronotum, but the latter has antennomere 3 distinctly longer than 4 and at least 3 times as long as antennomere 2. The apical portion of the male terminal abdominal ventrite (Fig. 18) is similar to that in N. sublineatus but its apex is less projecting posteriorly, and in lateral view (Fig. 24) its apical margin is thin (thickened and appearing double in N. sublineatus as in Fig. 25).

Description. Male. Length 7.7–10.5 mm, width 3.0– 3.4 mm. Body ( Fig. 45 ) narrowly elongate, 2.3–2.5 times longer than broad. Body brown. Upper surfaces matt, densely clothed in short and inclined, apically pointed setae. Head. Vertex with V-shaped ridge. Antennae serrate, short, reaching middle of elytra. Antennomere 3 weakly expanded apically, 1.7–1.9 times as long as broad, 1.0–1.1 times as long as antennomere 4; terminal antennomere distinctly longer than penultimate.

Pronotum 0.5–0.6 times as long as wide, widest just before base, sides from about middle more strongly converging anteriorly than posteriorly. Lateral margins narrowly explanate without marginal bead, edge smooth and without distinct fringe of setae, anterior angles obtuse, posterior margin distinctly crenulate. Disc moderately convex, punctation coarse and dense.

Pterothorax. Scutellum 0.9–1.1 times as long as wide, distinctly pointed apically. Elytra moderately convex, 1.8–2.1 times as long as wide, 3.8–4.6 times as long as pronotum, sides relatively straight, gradually narrowing in apical third, apices weakly prominent; lateral margins narrow with distinct bead, entirely visible from above.

Abdominal ventrites with glabrous spots on each side; ventrite 5 distinctly projected medially, 0.4–0.5 times as long as wide, 1.3–1.5 times as long as ventrite 4. Sternite IX apically rounded, at base emarginate, bearing uniformly short setae in middle and apex. Posterior edge of tergite IX straight or obtuse. Tergite X as long as or slightly longer than tergite IX, apically broadly rounded.

Aedeagus ( Figs. 46–48 ). Phallobase at base sinuate. Parameres longer than phallobase, straight apically, rounded at apex. Apex of ventral lobe narrowly rounded.

Female. Externally identical to male but with abdominal ventrite 5 truncate apically (Figs. 19, 44).

Types. Holotype (3): Queensland: Mt. Walsh, Nat. Park 7km E of Biggenden, 14-ix-1978, H. Fauca (13, ANIC). Paratypes (33, 2Ƥ): Queensland: Coast Range SE of Geisslers Biggenden, 5-x-1976, H. Fauca (13, ANIC); Kroombit Tops, 45km SSW Calliope, C, Qld. (Barracks, Open Fr), 29-xi-1985, G. B. Monteith (13, QM); Mt. Woowonga, c. 24km SW. of Childers Q, 30-xi-1975, H. Fauca (1Ƥ, ANIC); SEQ: 25°34'Sx 152°03'E Mt Walsh 1km N 320, vine scrub, PitFll 7882, 26.vi–9-x-1999, D. J. Cook (13, 1Ƥ, QM).

Distribution. This is the most geographically restricted species, with most of the localities in the area inland from Hervey Bay and near Gladstone, Queensland, north of the known range of the other species ( Fig. 51 ).
