I found this lil' fella (1cm size at maximum) in my bathroom. Actually, he's been there for a week or so, but I always left it be since it was scared of me and used to just stay in the corner of the room. This time, though, I found it in the middle of the room, and by trying to make it return to its usual corner, he turned quite aggressive and started chasing me, so I just brought him outside using a glass

Is this a Loxosceles rufescens? If it is, how do I recognize it? I've never seen one actually, so I wouldn't want to mistake some harmless spider for a Loxosceles
