Genus Titiotus
Numbers
16 species in BugGuide's range (North America north of Mexico).(1)
Size
Adult body length (excluding legs) of females: 11-21mm; males 8-17mm.(2)
Identification
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.(2)
Range
All species are only known from the state of California. See Platnick & Ubick 2008(2) for maps. See pages 7, 13, 30.
