Explanation of Names
Author of the name: Dufour. Year first published: 1820.
Range
Northeastern United States (1)
Remarks
An introduced species. The bites of these spiders do not produce the severe reactions typically associated with the brown recluse spider. (1)

"Loxosceles rufescens apparently has not been associated with cases of human loxoscelism, but in experiments done on mice and rabbits, the venom of L. rufescens has been found to have effects similar to those of Loxosceles reclusa (Smith and Micks, 1968; Shulov et al., 1962)" (2)
