Additional material studied. 17♂, Hellyer Gorge, TAS, 2. Feb. 1987, E.F. Riek coll. ( ANIC; in alcohol, poor condition).

Habitus. BL 2.5–3.0 mm, BL/BW ~1.7. Elongate, elytra largely parallel, flat. Brown, pronotal margins and humeral area may be a bit lighter than rest.

Male. T9: A fairly long basal sclerite strip connects the strong apodemes which are caudally continued by massive rods. Each rod medially with a narrow subterminal straight spike not reaching the swollen apex of the rod which carries a slender spine abruptly bent outward. S9 slender, setose apex parallel-sided, truncate.

FIGURES 115–120. Austrocyphon robustus sp. n., male. 115, T8 and S8; 116, T9; 117, S9; 118, tegmen and parameres; 119 and 120, penis in dorsal and lateral (dorsal is to the left hand side) views. All to the same scale.

Pala of penis much longer than distal part which is not flanged. Trigonium slender, centema a strong hook.

Tegmen long and slender, from the truncate base originate slender, caudally narrowing simple parameres.

Female. Not known with certainty, presumed specimens not distinctive.

Etymology. The name describes the robust build of the rods of T9.

Notes. Occasional females taken together with males cannot be identified and are not listed. The 5 paratypes from Quorn (in SAMA) were originally mounted on 4 cards on a single pin, together with a presumed female plus a male of Cyphon (s.l.) lindensis (Blackburn) ; an eighth specimen is now missing. They were believed to be syntypes of C. lindensis . However, since Quorn is not a type locality of Helodes ( Cyphon ?) lindensis they cannot be considered syntypes.
