Habitat
occur in diverse terrestrial including forest floors and ground-level vegetation. Leptoctenus byrrhus has been recorded from riparian areas in the southwestern United States. Mexican species have been collected in tropical and subtropical forest environments. Specific microhabitat preferences remain poorly documented for most species.
Distribution
The has a disjunct distribution spanning Australia (L. agalenoides), the southwestern United States and Mexico (L. byrrhus, L. gertschi, L. sonoraensis), southern China (L. daoxianensis), and Panama (L. paradoxus).
Behavior
As wandering spiders, members of this are active hunters that do not build webs to capture prey. They likely employ hunting strategies typical of the Ctenidae, pursuing or ambushing ground-dwelling .
