Crossopriza lyoni and maybe not - Holocnemus pluchei? - Holocnemus pluchei
Santa Clara, Santa Cruz County, California, USA
August 23, 2009
I'm wondering because Crossopriza lyoni possesses possibly the only tapered, pointed abdomen of the cellar spiders.

NOTE: The comments bellow are extremely confusing unless you realize I originally placed it with Harvestmen, not true spiders (very bad!). So Cellar spiders is correct, but which species? Crossopriza lyoni or Holocnemus pluchei?

I am not going to move it because the example below seems to support the original placement so both would have to be wrong. I'm just going to mention that it is a bit confusing to me, and see what others think.

Damn! Wrong again!
I did realize the morphological difference between spiders and harvestmen. I came a cross this image that I took a long time ago and thought that it was a funny looking harvest man from this angle. I am more than happy to discover the truth. Before you know it I will not only get the right order, I will even be able to name the occasional superfamily!

H. pluchei
This absolutely is a Marbled Cellar Spider, Holocnemus pluchei. They are introduced to California and are on of the most common spiders around buildings around the San Francisco Bay Area.

Cellar Spider
This is a cellar spider. Harvestmen & Cellar Spiders are easy to tell apart because cellar spiders have a head & a body (two parts)... while Harvestmen have only a body (one part)... with the eyes right on it. From the pattern on this cellar spider.... I'd guess that it might be Marbled Cellar Spider (Holocnemus pluchei).

Are you sure
it's not a Cellar Spider?
