The Lake Fenton Trapdoor Spider is a ground-dwelling spider growing to 1.5 cm in length, with a yellow-brown and strongly patterned abdomen. The species is only known from a few sites in southern Tasmania including Lake Fenton in the Mount Field National Park, where it occurs in subalpine woodland, and tentatively from the Tarraleah area, where it occurs in tall wet forest. Like other trapdoor spiders, the Lake Fenton Trapdoor Spider lives in burrows lined with silk. The burrows do not have a lid, are about 5 cm deep and entrances are about 1 cm in diameter. The key threats to the species are habitat loss through potential new tourist developments and maintenance of existing infrastructure, and from trampling or damage to the soft moss where the species makes its burrows. If the species is confirmed as more widespread (e.g. near Tarraleah), forestry activities may be a threat because the known sites may be within wood production forests.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
