Etymology. The specific epithet is a noun in apposition, taken from the type locality.

Diagnosis. Males and females of Austropholcomma florentine can be distinguished from A. walpole by the presence of eight eyes (Fig. 31B).

Description. Holotype male: Total length 0.82. Carapace 0.38 long, 0.31 wide. Abdomen 0.47 long, 0.45 wide. Leg I femur 0.27. Cephalothorax, abdominal sclerites, legs tan-yellow; abdomen cream. Carapace raised anteriorly, fused to sternum via pleural sclerites; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.75x diameter of ALE; PME separated by nearly twice their own diameter. Chelicerae each with large, bulging an- terior projection; promargin with single peg tooth and modified, proximally-flattened peg tooth-like seta projecting from fused setal socket. Legs relatively short (leg I femurcarapace ratio 0.71); macrosetae absent. Abdomen oval-globose, covered with hair-like setae, each seta projecting from small sclerotic spot; dorsal scute large, covering most of dorsal surface of abdomen; lateral sclerotic strips present. Pedipalpal patella with distally-directed, flanged lRPA and large, flange-like distal apophysis; tegulum smooth, without processes, with curved ETR; embolus long (length> 5× width), bifurcate, with proximal portion looping once around margin of tegulum, distal portion coiled and intertwined (Fig. 32).

Allotype female: Total length 0.89. Carapace 0.38 long, 0.29 wide. Abdomen 0.60 long, 0.49 wide. Leg I femur 0.26. Cephalothorax, abdominal sclerites, legs tan-yellow; abdomen cream. Carapace raised anteriorly, fused to sternum via pleural sclerites; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.5x diameter of ALE; PME separated by their own diameter. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femur-carapace ratio 0.68); macrosetae absent. Abdomen oval-globose, covered with hair-like setae, each seta projecting from small sclerotic spot; dorsal scute absent; lateral sclerotic strips present. Pedipalp small, four-segmented, with fused tibia-tarsus. Epigyne with distinctive external morphology (Fig. 30D); spermathecae globular, ‘tear-drop’ shaped; insemination ducts coiled around arched fertilisation ducts, insemination ducts with sclerotised proximal portion and expanded, membranous distal portion (Figs 33 A–B).

Distribution. Known only from Tasmania.

Remarks. Austropholcomma florentine is very similar to A. walpole from Western Australia. Nothing it known of its biology, except that specimens have been collected from moss and leaf litter, mainly in Nothofagus rainforest.
