Austrocyphon acaciae , sp. n.

( Figs. 81–85 )

Type material. Holotype ♂, 1 ♂ paratype: Acacia Plateau N.S.W. J.Armstrong / Cyphon fenestratus Id. by J.Armstrong ( ANIC).

Additional material studied. NSW: 1♂, same data, genital preparation incomplete.

Habitus. BL 2.3–2.4 mm, BL/BW ~1.5, resembling Austrocyphon pictus in shape as well as in elytral pattern. The dark holotype has only a round paramedian spot near elytral midlength, and a smaller one obliquely behind it and to its outside.

Male. T9 ending in two widely separate bare rounded lobes. Anterior limit of the U-shaped notch between them blending into a raised central area with some spicules. The raised area is anteriorly limited by a small pale arched area. Apodemes long, straight, connected by an arched antecosta. Apodemes caudally truncate, near their ends an arched pale window on either side of plate. S9 with two acute, easily seen, setiferous lobes, sides and narrow front part unsclerotized and barely visible.

Penis with shallow incomplete flange near midlength. Pala a little shorter and narrower than the caudal frame. No distinct transverse bridge. Instead, the narrow trigonium is supported by two sclerites curving out of the lateral frame. Claw-shaped centema without accompanying spinules.

Parameres slender, gently curved, apically pointed, originating from a small U-shaped capulus.

Female. Not known.

Note. The extended pointed caudal lobes of S9 distantly resemble A. asper , sp. n.

Etymology. The specific name is the scientific name of the wattle genus, in the genitive case, in reference to the type locality.
