Is this a Castianeira crocata? I’ve never seen this one before. Just found it in my basement.

Dear TK,
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.
