They are free-running ground dwellers.^[2]

Description

Trochosa are medium-sized spiders with general brown coloration. The body and legs are hairy and characteristically marked.^[2]

The carapace has a characteristic broad pale central band that is expanded anteriorly and contains two darker patches of variable extent and shape. The anterior row of eyes is slightly wider than the second row (the posterior median eyes). ^[2]

The legs are stout and not very long compared to body size. The fourth tibia has a proximal spine dorsally that is usually thinner or more drawn out than the distal one, and is sometimes reduced to a bristle.^[2]

Taxonomy

This genus is well-known in Europe and North America but has never been properly revised from Africa. The male genitalia closely resemble those of Hogna, making them of limited use for generic diagnosis.^[2]
