- Baja California to New Mexico (according to this
eclectica (longipes) - southwestern United States
pallida (might actually be a Zorocrates sp.; see remarks below) - southwestern United States; Nathan Banks' type species was found in Mesilla Park, New Mexico.
tigrina (synthetica) - southwestern United States
Mature adults usually found in spring and summer.
According to aces.nmsu.edu
- Syspira longipes
Simon (= S. eclectica
Chamberlin) and Syspira tigrina
Simon (= S. synthetica
Chamberlin), but they are all listed as separate species on the World Spider Catalog. A revision of the genus is probably due.
