Lycosidae (wolf spiders)

of Arkansas

Click here for Scans of selected species from Kaston

 

Distinctive eye arrangement with four small anterior eyes in a row and four posterior eyes that are larger and form a quadrangle. Females distinctively carry the egg sac with them and then the hatchlings on their backs. Bracketed numbers are number of NA species in the new Spider Manual and on the internet family site. (This internet list of species is here.) I have 76 species possible locally after this last update. Though the status of several is unknown and the genus Lycosa seems to be under revision and puzzling. Peggy Dorris found several species in Pardosa that seem unlikely to have occurred in AR but I have no further work on this for now. They are currently listed below for AR.
