Infraorder Mygalomorphae - Mygalomorphs

A very complete site that lists tarantulas by species name... the biggest tarantula picture archive in the net by the leading tarantula expert, Rick West.

The Nearctic Spider Database aims to consolidate images, distribution maps, and species descriptions for all species of spider found in North America.

This is an authoritative checklist that aims (pretty much successfully) to list every species of spider ever recorded from California, along with synonyms, range (given in terms of counties) and citations of references in the taxonomic literature. It won't tell you how to identify any spiders, nor will it tell you anything beyond classification and range of species- but it will tell you the names and synonyms of species in a given county so you can look them up elsewhere.

Information and myth-debunking on poisonous spiders in Southern California. Includes extensive info on the brown recluse spider; also brown widow, "blush spider," daddy long-legs, and hobo spider.
