Species here were all previously in the genus Tegenaria.

Recognition of Eratigena atrica as three separate species (E. atrica, E. duellica, and E. saeva) restored via "Oxford & Bolzern, 2018".(1)
Explanation of Names
Bolzern, Burckhardt & Hänggi, 2013(2)

Eratigena is an anagram of the genus Tegenaria.(2)
4 species in BugGuide's range (North America north of Mexico).(3)
Eratigena agrestis: Europe to Central Asia. Introduced to USA, Canada(3) - CO, ID, MT, OR, UT, WA, WY, AB, BC, ON (Rouge River area of Pickering, Ontario is a recent accidental introduction)(4)(5)
Eratigena atrica: Europe. Introduced to Canada, USA(3)
Eratigena duellica - Canada, USA, Europe(3) - main population located in BC, OR, & WA.(4)
Eratigena saeva - Western Europe, Canada(3)

Also collected from isolated populations in AB, SK, QC, NS, NF.(5) - Access needed to cited material to sort out which species this line refers to now that the synonymy between E. atrica, duellica, and saeva has been undone.
Eratigena atrica is the type species.(3)

E. duellica, and E. saeva can hybridize with one another.(1)
