Brown recluse spiders are usually between 6–20 mm (this one was only about 2 mm), but may grow larger. While typically light to medium brown, they range in color from cream-colored to dark brown or blackish gray. The cephalothorax and abdomen may not necessarily be the same color. These spiders usually have markings on the dorsal side of their cephalothorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames fiddleback spider, brown fiddler or violin spider.
This tiny spider lacks the classic "violin" pattern on the thorax but otherwise looks like a brown recluse physically & has the same arrangement of 3 pairs of eyes. I regularly have to evict brown recluses from our bathroom so I'm pretty certain on the ID,
