Genus Syspira
Synonyms and other taxonomic changes
Genus needs a revision; there could be only 3 species in North America, but the WSC lists 4 (published literature is outdated).
Can reach up to 18mm in body length.
analytica - Baja California to New Mexico (according to this NMSU website)
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
Desert areas.
Mature adults usually found in spring and summer.
According to - 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.

According to Dr. W.J. Gertsch (pers. comm. to Jack Olmstead), Syspira pallida Banks is actually a Zorocrates (Zorocratidae). (Olmstead, 1975, unpublished thesis)
