Spiders of Texas
"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."
"This list contains 1000 species in 52 families. Many more species remain to be discovered."
