Etymology
Etymology: In honour of Dr Geoff Monteith without whose strident activities over the past 35 years the invertebrate fauna of eastern Australia would be much more poorly known.
Diagnosis
Diagnosis: Males differ from those of A. toddae in smaller subbasal mounds on RTA and relatively broader median apophysis, and from those of A. hackerae in the broad retrobasal cymbial flange, distinct retrodorsal cymbial cone, and the ventral groove of the embolus is open only on the tip. Females differ from thoose of A. hackerae in the shorter more deeply recurved invagination on the posterior septum and relatively broader anterior portion of the anterior septum.
Description
Description (Holotype male QM S 57227) Caparace 4.43 long, 3.58 wide. Abdomen 3.69 long, 2.27 wide. Colour. Pattern on carapace and abdomen similar to A. hackerae (Fig. 4). Palp. RTA subdistal with simple single apex with two small mounds subdistally of tip; ventral tibia-cymbial interlocking process distinct; lateral one not so evident; basodorsal cymbium rounded, not posteriorly projected (Fig. 7b cf. 5e); median apophysis large, origin is central on tegulum; similar in overall length to bluntly tipped embolus; longitudinal extents overlap by 30-50%. Ventral groove of embolus closed for almost its entire length, only open near the tip.
