Picture of unidentified spider

Comments & ID Thoughts

Well, this spider was found in a tangled-web and there seems to be some sort of indent on his/her back? Perhaps just a darker arrow shape on its abdomen? The legs seem to be quite long, thin, and are darker around the joints. Probably not much bigger than a school eraser, smaller than a doorknob.... Identification would be appreciated! Thank you

Hi, it might be a cellar spider in genus Pholcus. They have leg joints that look like that. The tangleweb is from a spider in family Theridiidae. They include the false widows. They prey on cellar spiders when they can. The indent is probably where the tangleweb spider plunged its fangs into the other spider to inject venom and digestive juices. It is an interesting photo. Tangleweb spiders AKA/ cobweb spiders are killing cellar spiders in my house but it mostly happens in the dark and I don’t have photos.
