Is this a Castianeira crocata? I’ve never seen this one before. Just found it in my basement.
You are correct. This is a Ground Spider, Castianeira crocata, and BugGuide does not list a common name. According to SpiderzRule, a close relative in the same genus, Castianeira descripta, is commonly called a Red Spotted Ant Mimic Spider. This is not considered a dangerous species to humans.
