The unusual character combination of three claws plus claw tufts readily separates members of
Titiotus and their closest relatives from most other North American spiders. Males of
Titiotus differ from those of the other three closely related genera (
Liocranoides,
Anachemmis, and
Socalchemmis) by having a tibial apophysis consisting of three or four prongs (rather than just one or two); females differ by having a wide median septum that usually occupies more than two-thirds of the epigynal width.
