Maintained by Mark Harvey of the Western Australian Museum. I found out about this through an International Society of Arachnology email.
Summary:
A comprehensive source of information on pseudoscorpions with a world catalog, a general description and excellent photo guide to families
From the home page:
Welcome. This website is designed to provide some basic information on the wonderful world of pseudoscorpions and, in particular, provide lists of valid names and a comprehensive list of the scientific literature that deal with pseudoscorpions. I would be grateful to receive any information that might be used to improve the website, in particular any errors or omissions that occur within the website.
I propose to update the website at regular intervals. This website contains published data up to the end of 2007. I would be most grateful if colleagues could continue send me copies of their publications for inclusion in the catalogue.
There are updated species lists for each country, and here's the links for the US and Canada:
