    They usually have a brown cephalothorax with diffuse, indistinct darker brown markings on the legs and abdomen. The underside of the abdomen has a characteristic yellow marking with no spots. The genus Tegenaria has recently been split: Tegenaria spp. have banded legs, Eratigena spp. have plain legs.
