Help ID Hitchhiker Crab

[labas39]

I found this crab dead on my cyphastrae today. I couldn't find anything like it searching the Net. Any thoughts?

Black claws = bad crab!

you sure that isn't a molt? Eyes look empty. I agree that it looks dangerous, so hopefully it isn't a molt. . .

It could be a molt, probably why it was just sitting there. How can I trap him?

 

[Herbie]

you can try tipping a pint glass against your rocks with some food in the bottom. you'll probably catch all of your crabs that way

Should I fill the pint glass with Guinness?

well I'd hate to use a brand new clean glass in my tank. . .
