Species here were all previously in the genus Tegenaria.
Explanation of Names
Eratigena is an anagram of the genus Tegenaria.(1)
2 species in BugGuide's range (North America north of Mexico).
Eratigena agrestis: non native - CO, ID, MT, OR, UT, WA, WY, AB, BC, ON (Rouge River area of Pickering, Ontario is a recent accidental introduction)(2)(3)
Eratigena atrica: non-native - main population located in BC, OR, & WA.(2) Also collected from isolated populations in AB, SK, QC, NS, NF.(3) Please note that in 2013, three species were synonymized (duellica, saeva, & atrica), so many of the populations in Canada, aside from BC, were of what was (then) considered a separate species.
