Attack of the Pseuton Spiders! Could This Be Their Leader? - Holocnemus pluchei
Fullerton Arboretum, Fullerton, Orange County, California, USA
April 8, 2010
Hunched over the computer, I'm puzzling over the ID of several spiders. Grandson Owen peers over my shoulder and volunteers: "Oh, those are Pseuton spiders." I have reason (scant) to believe that this small individual is their leader, perhaps a plucky male among fervent female warriors.

This is H. pluchei, the Marbled Cellar Spider, normally identified by its diagnostic wide, black ventral stripe (not visible in this picture). Among California's pholcids, only H. pluchei has this unique "marbled" appearance. It was introduced from the Mediterranean region and is now widespread throughout the southwestern United States. This individual appears especially contrastingly marked, and based on its coloration (light brown instead of dark) and size, this spider is likely a juvenile.
