Etymology
Etymology: In honour of Mr Jeff Wright, Queensland Museum, whose consummate skills in the photography of small terrestrial invertebrates are honored.
Diagnosis
Diagnosis: Females differ from those of A. toddae by the broader epigynal plate without posterior deep invagination; males of the two species are best separated by the clearly dissimilar lobes of the RTA. Males differ from those of A. monteithi in the broad retroventral cymbial flange and the apex of the embolus is arrowhead-like. Males with conical extension of cymbium basally over tibia; epigyne with broad anterior septum and posteriorly set lateral teeth.
Description
Description (Holotype male QM S 28845) Carapace 3.94 long, 3.25 wide. Abdomen 3.88 long, 2.31 wide. Carapace, legs, spines and chelicerae as in A. toddae.

Tibia distally with 2 apophyses: ventrally a process forms notch in which complementary lobe on retrobasal cymbium interlocks; prolateral of that process a concave invagination prodorsally bounded by low ridge, which fits into a groove on prodorsal cymbium basally. Cymbium dorsally forms cone extending basally over distal tibia; dorsal scopula absent; retrolateral groove absent; retroventral flange of cymbium distinctly widened. In resting position, cymbium twisted so that normal ventral face diagonally faces ectally. Tegulum conical with large median apophysis and slightly smaller embolus; longitudinal extents of which overlap by 30-50%. Ventral groove of large embolus widely open for its length and tip arrowhead-like. Description (Allotype Female QM S 28842) Carapace 3.60 long, 3.80 wide. Abdomen 3.88 long, 2.60 long. Colour. As for A. toddae but coxae dorsally yellow brown with broad light shadow stripe. Epigyne. Broad, ventrally flat or slightly concave, broadly pear-shaped with broad anterior septum, widest point in posterior fifth, posteriorly slightly concave; lateral teeth set posterior of widest point, short conical directed medially and posteriorly. Genital opening plugged with more than just embolus. Spinnerets. Expanded, two lines, each of 4, of largest spigots on spinnerets on PMS dorsally and, as with ALS and PLS apically with ring of smaller but long spigots; PMS as long as PLS, conical.
Distribution
Distribution and Habitat: Known only from rainforest at Mt French, southeastern Queensland and in northern New South Wales at Beaury State Forest.
