Catalogue of Texas Spiders
by D. Allen Dean


Gertsch & Mulaik started a list of Texas spiders in 1940. In a letter from Gertsch dated October 20, 1982, he stated “Years ago a first listing of the Texas fauna was published by me based largely on Stanley Mulaik material, but it had to be abandoned because of other tasks.” Vogel (1970b) published the Bibliography of Texas Spiders and recorded 560 species. This catalog is an update of Vogel’s list. Thanks to Dr. Norman Horner (Midwestern State University) for providing state records from his database.

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.

This list contains 1081 species in 52 families.
