It’s one of the Pholcoid Cellar spiders. The markings don’t look like P. phalaniodes. I’ll look for more info.


https://bugguide.net/adv_search/bgsearch.php?taxon=9608&location%5B%5D=MI BugGuide has more years of data than we do, the link is to their data for Michigan for family Pholcidae. They couldn’t ID to species level the lateral photos and the photos that don’t clearly show the dorsal markings. The cephalothorax of yours has a black marking that splits into a Y. P. phalangiodes has a big dark dot in that spot. I’ll keep looking.


It doesn’t match any of BugGuide’s “cheat sheet” images of common introduced Pholcus spp. It might be one of the rarer native species that they haven’t received photos of. Please submit the photos to Bugguide.net with the title Endemic Pholcus Species? Please let us know what they say.
