The H. agilis group includes three species in California plus Baja, two of which are endemic to the region. All three species share the stiff setae along the lateral margins of the face, giving them a "mustached" look. All species also have a well-developed stridulatory organ at the cephalothorax - abdomen junction, and characteristic first leg fringes. The species of this group are perhaps more ecologically generalized than any other CA Habronattus (aside from H. hirsutus), and can be found both on the ground and in vegetation in a wide variety of habitats. However, the species do seem to prefer habitats with sandy substrates, and are commonly encountered in either riparian situations or along the coastlines.

H. elegans - an endemic of southern California and northern Baja west of the deserts. Clearly a close relative of H. peckhami, and in close parapatry in Santa Barbara county.

H. peckhami - An endemic of central California west of the Sierra Nevada. According to Griswold, the species differs from H. elegans in having the anterior surface of tibia I covered with fine, black scales rather than fine, white scales.
