Arachnid Resources

General Interest
  • Spiders.US An International Spider Community with a North American Focus. Spiders.us serves as a community as well as an informational and pictorial library providing accurate spider identification resources to the public. Our goal is to dispel myths, superstitions, and urban legends that cause many people to be fearful of spiders. We empathize and promise to put the squeamish and scared at ease as best we can. We will also defend spiders for the important roles they play in nature, natural pest control, medicine, engineering and other economic and cultural realms.

Sites based on Geographic Location
  • Spiders of the Arid Southwest. Site at New Mexico State University edited by David Richman, Allen Dean, Sandra Brantley and Bruce Cutler. The arid Southwest can be defined as being composed of the states of Arizona and New Mexico, and part of the states of California and Texas and possibly Utah and Nevada. The northern parts of the Mexican states of Baja California Norte, Sonora, and Chihuahua could also be included in this region. The current work is, however, centered on the Arizona-New Mexico-Trans-Pecos Texas part of the arid Southwest, although it should be useful in the other mentioned areas.
  • Texas Spiders. This catalog is an update of a 1970 list put together Bea Vogel. Texas is a transition zone which includes extreme limits of many species and also has part of its border adjoining Mexico. The climate varies from subtropical in South Texas to temperate conditions in the panhandle and from desert in the west to swamp in the east.
  • Araneomorphae of Mexico. These WebPages are intended to allow comparisons with other faunistic inventories; in particular, for morphospecies either new or difficult to identify because of the lack of taxonomic revisions. These images are also intended to expedite the identification process for difficult taxa by sharing them with other Arachnologists and to collaborate in species descriptions

Sites on Taxonomy and Taxa
  • Arthropoda Cytogenetics. The cytogenetic analysis that has been accomplished in different groups of Arthropoda has the aim of understanding the mechanisms related to the chromosomal evolution, the events responsible for intraspecific and interspecific variability in diploid number, the origin and differentiation of the sex chromosome systems. The mitotic and meiotic chromosomes have been investigated using classical, molecular and ultrastructural methodologies.
  • The World Spider Catalog, maintained by the Natural History Museum Bern, Switzerland. First fully searchable online database covering spider taxonomy. After important first paper versions from Bonnet, Roewer, Brignoli and Platnick, this open access database includes all taxonomically useful information for all described spider species. Moreover, the World Spider Catalog Association provides free access to these references for its members.

  • The Scorpion Files. Jan Ove Rein's excellent site contains information about and pictures of scorpions; also literature citations, and weblinks.
  • Kari's Scorpion Pages. A personal site maintained by Kari J. McWest. Although different from the sites above in that it contains lots of personal information probably not of arachnological interest, the site does contain a series of links to other websites that feature annotated checklists to the scorpions of the United States.
