Approx. 240 species in 21 genera in North America north of Mexico. Exact numbers and recognized genera are subject to change. Note that at the time of this writing the World Spider Catalog(2)
lists 9 species of Lycosa
in North America, these are not included here because they likely all belong to other genera. It is noted in "Spiders of North America: An Identification Manual" By D. Ubick, P. Paquin, P.E. Cushing and V. Roth (eds)(1)
that "the genus Lycosa
Lᴀᴛʀᴇɪʟʟᴇ 1840b is properly restricted to a group of large burrowing wolf spiders in the Mediterranean region. Consequently this genus is not represented in North America, and the species listed from this continent by Platnick (2005) require revision and placement." One species of Paratrochosina
is also not included here as in SoNA(1)
it is suspected of being a misidentification of the highly variable Alopecosa hirtipes
, more information is needed.
