Tasmanicosa phyllis, commonly known as Phyllis’s wolf spider, is a species of Australian wolf spider in the family Lycosidae. It is endemic to Australia and is typically found in open habitats such as heathlands, grasslands, woodlands, and sandy coastal areas, where it shelters in burrows or shallow retreats in the soil.

Like other wolf spiders, it is a fast, ground-dwelling hunter that does not build webs to catch prey. Instead, it uses keen vision and vibration sensing to locate and pursue small invertebrates on the ground, usually becoming most active at night.

It is generally a robust, brown to grey spider with a orange hue and a mottled or patterned appearance that helps it blend into leaf litter and dry ground. Adults are medium to large in size, with females typically larger and more heavily built than males. Its burrowing lifestyle and nocturnal hunting behaviour are characteristic of the genus.
