Moved from Ceraticelus.

Moved from Spiders. Probably C. fissiceps. Moved to genus page for now.

Ceraticelus
I think you are looking at either C. fissiceps or C. atriceps.

 
Thanks Chad
I replaced the last palp image with one that has focus on the small clear structure corresponding to the one in the C. fissiceps you IDed for me previously and it appears to be more rectangular on this one which would seem to be more like C. atriceps?

 
Hmmm
I think it is important to have multiple characteristics to confirm an identity if possible. I am leaning toward C. fissiceps for the following reasons: 1) The anterior knobs of the cepthalothorax look more like that of C. fissiceps with two distinct lobes. 2) While I agree that the small clear structure appears to be more rectangular, it is not distinctly so. Furthermore, the dark scleratized part immediately in front of it on #945223 appears to narrow at the terminus rather than being broadest there as in C. atriceps. I always find, especially with these dwarfs, that there is no substitute for looking at the actual spider--pictures just don't do it. If you have still have the spider, pull it out and look at it a little more closely and you should be able to convince yourself one way or the other. At least you have it narrowed to two species!

 
I haven't been ...
doing a good job of saving spiders either. I saved a few in a very unprofessional manner in assorted pill bottles, contact lens containers etc.... I really need to order vials one of these days. What have you been storing yours in?

 
For things I collect
I have assorted sizes of centrifuge vials that I buy on ebay for cheap, most of them from China. The smallest ones are .2ml which are tiny, the biggest are 5ml, good for fairly large bugs/spiders around the size of say a larger Xysticus.

 
Thanks ...
they look they'd be good for storing a lot of them in a bigger glass jar. with alcohol.

 
They seem to work well
They are plastic with snap caps attached. I have been using them for saving specimens that I send to people for identification. The specimens are usually in alcohol and they appears to seal well. I generally have a bunch of vials laying on their sides on my desk and they don't seem to leak unless I've opened and closed them a whole bunch. Not sure if they would be good for extended storage without doing something like you are suggesting.

 
Thanks for the detailed explanation!
I haven't been saving spiders, I'll look for another one. I did dissect a female C. fissiceps recently so they must be fairly common here in my yard.
