I found this spider crawling on my tile floor. We live in rural central Virginia. I’ve found spider species with similar looks but nothing exactly like this. Its size was less than 1 inch. Can anyone identify it?
I agree with JulPal's comment from August. It looks very much like a male Thiodina (now renamed Colonus) sylvanus. As with many Salticids, the females look rather different, and it turns out that there is apparently a similar species of Colonus in the area, which can be distinguished in the field by the fact that the white mark on the carapace is not a block so much as a thick longitudinal line. I attach an image from Tree of Life, with the link below:
