( Figs. 145–149 View FIGURES 145 – 149 )

Type material. Holotype: ♂, Australia, ACT, Molonglo River at Coppins Crossing, 20.X.2007, P.Zwick, swept from littoral vegetation ( ANIC). Paratypes, QLD: 5♂, 24 ml. SW by W of Kingaroy, Q. 26.44S 151.31E, 21.xi.1968, E.Britton & S.Misko; 1♂ (plus a presumed ♀), Woombye, Q. nr Nambour 16.x.65 D.H.Colless; 1♂, Rocky Ck., 7 M. N of Atherton N.Qld. 3 May 1967 D.H.Colless (all ANIC).

Habitus. Slender, elytra almost parallel-sided. BL 2.0– 2.7 mm, BL/BW ~1.7. Holotype blackish, the other (older, faded?) specimens dark brown, tibiae lighter.

Male. T9 lateral rods gently upcurved and caudally a little clubbed. End of rod with an eccentrical oblique small finger, ventral edge of club angular, in some positions almost tooth-like. S9 weakly sclerotized, caudally shallowly concave, with fine pilosity.

Tegmen with U-shaped capulus, the slender pointed parameres with a subterminal hooklet on outside.

Pala narrower than distal part of penis. Parameroids not flanged but forming a very long caudal frame which is distinctly excised at tip. Trigonium short, wide, smooth, centema much narrower than truncate tip of trigonium.

Female. The presumed female is not distinctive.

Notes. The appearance of the easily separated rods of T9 depends on their position in the microscope preparation ( Figs. 146, 147 View FIGURES 145 – 149 ). Specimens from Queensland are only 2.1–2.2 mm long, while the holotype from Canberra measures 2.7 mm.

Etymology. The name refers to the shape of the penis apex, Latin excisus , excised.
