Can some ID this please?

Thank you.

Actually after further research I believe it is of the species D. aquaticus.

Thank you for trying.

Moved
Moved from Dolomedes gertschi. Yes, that looks good. Please post those images of D. gertschi. I'd really like to see them. Thanks!

 
D. gertschi pics posted

I wish we could see the entire habitus on the male, but I guess these were the only shots she had.

Tinus?
I've seen images of verified D. gertschi (from Gail Stratton) before and this doesn't seem to look like one. Her male had lightly banded legs and the carapace pattern was different. Is there any way this could be a male Tinus peregrinus instead? I don't have hands-on experience with those two species, so just wanted to see what others had to say. I'm only working off of other images I've seen.
I'm probably going to ask Gail if we could post her scanned photos of D. gertschi to BugGuide. It's surprising how much the female of that species looks like D. scriptus.

Hi, Jeff- What are the sig
Hi, Jeff-

What are the signifying characteristics one should look for? Here is another image, also of a male, that is likewise identified, but it looks somewhat different (at least in markings and coloration):

...
I think that one looks different because it's actually D. triton, not D. gertschi.

 
Yes
it does look different, and gertschi is not described as being that dark, although this one seems to be on the lighter side.

 
Which brings up another quest
Which brings up another question that we forgot to ask: where did you find it (what sort of habitat -- assuming it wasn't on the living room wall)?

Size?
You didn't include a body size, which would be useful -- even if you no longer have the spider, you can measure the height of the 'G' on the lid. Do you have any better images?

 
Re: Size
I didn't post the picture, but I have the exact same type of container so I could measure the 'G'. The letter is 15mm, so the spider's body is about 13mm long. I used an application called Snake Measurer to get the length... I originally got it for my reptiles but it is also extremely useful for measuring arthropods as well (not trying to advertise, I'm just recommending it because it is a very neat tool).

No this is not a dangerous spider.
I think it is probably a Giant Crab Spider. See these images.

 
Pisauridae?
I would sooner suspect one of the nursery web spiders in the family Pisauridae. This specimen might be a male, as males have very long legs compared to females.
