Comparison of Pelegrina epigyna:
In order left to right:
aeneola, exigua, flaviceps, galathea, insignis, proterva
Maddison states that without in the hand examination P. proterva cannot be distinguished from P. insignis (and his map of the latter species shows a record for VA.

Yet he also indicates that P. proterva is typically found in woodland understory whereas P. insignis is found in open habitats like fields, shrubs, and bogs. --ChH

Eris - Eris has proportionately smaller palps, and a carapace that's more robust compared to Pelegrina. Also, I don't think any Eris have white scales under the ALE. Overall size is probably the easiest way to tell the difference. Once you've seen both genera you'll wonder how you ever got them mixed up.

I believe most (or all) male Pelegrina also have white scales beneath the ALE.
