Picture of unidentified spider

Comments & ID Thoughts

I think it could be an Artema atlanta (Giant Daddy-long-legs Spider) but I am not sure. It looks similar to same spider listed on this site. I Live in Buckeye, AZ and I last traveled to Lahaina, Maui, Hawaii, in early March of this year (2022). Thus far according to this site AZ and HI are the only places where this spider was photographed.

This spider was found in between my sectional sofa located in my living area as I took the sofa sections apart to re-arrange the spider began to scramble around. I captured and observed via a digital microscope.

I have multiple photos to submit, if the admin has an email or a way for me to upload multiple photos to the site that would be helpful.

Tentatively Physocyclus enaulus https://bugguide.net/node/view/669178/bgimage Your spider does have faint bandings but you are correct, this is not Artema atlanta. The markings don’t seem to match with that species of Cellar Spider.

I don’t think the extra photos are really needed. I’m pretty certain this is a Physocyclus sp.. I’m not familiar with any other Pholcidae species that look like this in your area. As well, the eye pattern is visible in this photo and matches with Physocyclus spp..

Also this website does not currently allow for adding multiple pictures to a post. Sorry about that. Typically, all you really need is a solid, clear, dorsal pic of the spider like the one you provided. Sometimes a ventral picture will help or a picture of the eye arrangement can be helpful sometimes. When it comes to some ID’s, clear pictures of the epigynum of a mature female or a picture of the pedipalps of a mature male is the only sure way of getting the species ID’d.

This species is small. Based on that size, this should be an adult. Also this genus of Cellar Spider seems to have very large pedipalps for mature males. https://bugguide.net/node/view/669180 Your spider’s pedipalps are not as large and are consistent with a female’s pedipalps. Females do not use their pedipalps as sexual organs, only males do. Hence the enlarged and much more intricate pedipalps of male spiders. This should be a mature female. Again, adults of this genus seem to be about 5-8 mm on average in total body length. The TBL is measured from basically the face of the spider… Read more »

Thanks for finding a new way to post photos to the discussion section! Youtube links work for videos.
