Dascillus brevicornis Macleay, 1872: 313 .

Notodascillus brevicornis: Carter, 1935: 186 .

Diagnosis. N. brevicornis is easily distinguished from the two remaining Australian species in having a strongly elongate antennomere 3 that is distinctly longer than 4 (Fig. 26).

Description. Male. Length 6.7–8.5 mm, width 2.6–3.3 mm. Body (Fig. 31) narrowly elongate, 2.5–2.6 times longer than broad. Head black or dark brown, remaining body parts brown. Upper surfaces matt, densely clothed in short and inclined, apically pointed setae. Head, pronotal and elytral setae mixed dark brown and yellow, elytral setae denser on alternate intervals and forming longitudinal stripes, venter covered by whitish dense pubescence. Head. Vertex with V-shaped ridge. Antennae serrate, short, reaching middle of elytra. Antennomere 3 parallelsided or weakly expanded apically, 1.7–2.0 times as long as broad, 1.2–1.3 times as long as antennomere 4; terminal antennomere distinctly longer than penultimate.

Pronotum 0.6–0.7 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 0.9–1.0 times as long as wide, distinctly pointed apically. Elytra moderately convex, taken together 1.9–2.3 times as long as wide, 4.2–4.3 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, 0.6–0.7 times as long as wide, 2.0–2.6 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. 32–34). 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 broadly rounded apically (Figs. 15, 30).

Type. Lectotype (sex unknown, abdomen missing): “K204442/ K33134 / Holotype / Dascillus brevicornis W.T. M. Gayndah ” (AM, here designated).
