Synonyms and other taxonomic changes
Numbers
Genus needs a revision; there could be only 3 species in North America, but the WSC lists 4 (published literature is outdated).
Size
Can reach up to 18mm in body length.
Range
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
Season
Mature adults usually found in spring and summer.
Remarks
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.
According to Dr. W.J. Gertsch (pers. comm. to Jack Olmstead), Syspira pallida Banks is actually a Zorocrates (Zorocratidae). (Olmstead, 1975, unpublished thesis)
