Size

How big was this mama? I'm just curious because some of the pholcid genera are smaller than others, so having the size recorded might help in the future when/if this family gets worked on here. The size of the eggs in relation to the size of the adult makes me think this is a small spider.

Excellent macro-shot! This is clearly Spermaphora senoculata, an introduced Old-World pholcid commonly found around homes in North America. This is based on its size, the fact that it appears to have a shallow procurved groove on the carapace, not a deep depression, and most telling, it only has six eyes (not eight). It can be keyed with these features using the Spiders of North America: An identification manual.
