Diagnosis
Diagnosis: Males differ from those of A. monteithi in the longer, more slender median apophysis and the ventral groove on the embolus is open for its length and from A. wrighti in the small retroventral flange on the cymbium and the simple tapering embolic tip. Females diifer from those of all other species in the less anteriorly narrowed anterior "neck" of the median epigynal scape and its overall narrowness.
Etymology
Etymology: In honour of Penelope Hacker, a much admired animal carer, and in whose backyard at Mt Glorious the species continues to thrive.
Description
Description (Holotype male QM S 51224) Caparace 2.93 long, 2.15 wide. Abdomen 2.70 long, 1.56 wide. Colour in alcohol. Pattern on carapace and abdomen faded. Legs. Tibia to tarsi of all legs with long recurved hairs for length on all faces. Spines: Tibiae I, II: 5 strong pairs ventrally plus pair of small on distal edge; metatarsi I, II with 3 strong pairs ventrally. Claws: paired claws dentate, not noticeably long. Palp. Distal cymbium with noticeably denser brush of hair; cymbium viewed retrolaterally with distinct basodorsal conical mound; retroventral flange small. Tibial apophysis subdistal with pair of dissimilar apices; ventral tibia-cymbial interlocking process small but distinct; median apophysis long, slender, apically folded, origin subcentral on tegulum, shorter in overall length than apically pointed embolus, median apophysis lies within longitudinal extent of embolus. Ventral groove in embolus a distinctly open groove for length.

Abdomen 4.41 long, 2.54 wide. Colour. Pattern on abdomen faded but more evident than in male. Legs. Spines, tibiae and metatarsi I, II as in male. Paired claws noticeably elongate, especially on IV. Epigyne. An almost parallel-sided median plate, slightly widened at posterior third, at which point medially is a short recurved ridge over the posterior invagination from the otherwise distinct posterior margin; bases of short concial lateral teeth arise just posterior of the line of recurved ridge, teeth directed diagnoally posteriad and line of apices lies just posterior to line of posterior margin. Genital opening plugged for two-thirds its length from proximad by lamellate portion of male palp.

Distribution
Distribution and Habitat. This most widespread species occurs from Wrattens Camp in the north and as far south along the Conondale Ranges to Mt Tamborine, one range north of Lamington National Park. It occurs coastally in a retreating rainforest (Buhot) in south-eastern Brisbane west to the Great Dividing Range at Ravensbourne. All areas are rainforest or at least closed forest.
Discussion
Remarks: One female (QM S 19605) was taken in a Myrmecia nest.
