Larinia

I don't know much about this genus. I tried reading a PDF article found here From reading parts of the article it seems to say that directa is the only American species while borealis and famulatoria can be found in Mexico.

"Levi (1975) revised and illustrated the three North American species
of Larinia: L. directa (Hentz), L. borealis Banks and L. famulatoria
(Keyserling)."

"Diagnosis. Larinia directa differs from other species south of
Mexico in the wide distal lip on the epigynal scape (Fig. 1) and the
tubular embolus lying diagonal to the main axis of the palp (Fig. 5).
In Mexico two similar species are found: Larinia famulatoria
(Keyserling) and L. borealis Banks. Both are illustrated and keyed
out by Levi (1975)."

Levi paper -

The 1975 Levi revision is also available online through the Biodiversity Heritage Library (page 101-135; see maps on pages 105 and 108 here) and seems to show all three of the species you mentioned in the US. :( He does give a key to separate the species, and we may be able to do so?

Here's the info from Spiders of North America

SoNA
(Probably derived from Levi)

Genus Larinia Simon, 1874 [3 species]

Larinia borealis Banks, 1894
NH, MA, NY, CT, ON, VA, MI, OH, IL, WI, KS, CO, NM AZ, UT, CA, WA, AB, SK, MB
(Looks like anything in Canada, the far northern tier of states, The Great Lakes, and the Northeast is borealis)

Larinia directa (Hentz, 1847)
CA, AZ, TX, AR, LA, MS, TN, AL, GA, FL, SC, NC, VA, NJ, OH
(Looks like anything tropical or very far south plus anything in the southeast, Arkansas to NC and south is directa)

Larinia famulatoria (Keyserling, 1883)
CA, ID, UT, WY, CO, AZ, KS
(These are the states where we'll have trouble, overlapping borealis to the north and directa to the south)
