Spiders of Baja California

The following checklist is preliminary and hopefully will be useful for environmental management and planning as well as a starting point for further biological studies of the regional spider fauna. Citations refer to papers with locality information, descriptions, or nomenclatural notes. As the author is relatively new to arachnology having "jumped ship" from herpetology he welcomes any comments, additional records and, especially, corrections. Classification generally follows Roth (1993). Families are arranged alphabetically within the mygalomophs and araneomorphs to permit more efficient access to a particular taxon by those unfamiliar with spider taxonomy. This list shows 43 families, 151 genera and as many as 411 species.
