I found this info on the sellers forum, apparantly its an Indian freshwater species,
http://www.franksaquarium.com/phpBB/view...7f9fd5d0a9
I dont know if the seller would reply back if I asked for more pictures, as I wouldnt be able to order directly from them, since they dont ship to the UK, I may be able to order crabs with the same name though, which I'd guess would likely be the same species.

Hi Kevin
First: I know this crab (or the genus), have to take a look at the weekend.
Second: You CAN write Frank and answer friendly, he's more a hobbyist than a business man (he's even registered here in our board but hasn'T posted yet) and will answer You (if he HAS more photos I don't know of course). He's a nice guy, tell him greetings from me. And ask where he's got 'em from. Since he is trying to build interest in freshwater/terrestrial crabs in the USA, „but the importers are so reluctant to bring in anything unusual. Very frustrating“ I think he will frankly tell You.

Frank has replied that he would be able to get more pictures, is there any particular pics that would be useful in identifying them?

Ahm, yep: Carapax seen from above, scissors (from the front, with scissor arms from the back/inside), from below (pleon), mouth parts…

Okay, found it – we both saw it here in the board: Sartoriana spinigera is correct.
Common species in India, German trivial name "Indische Trapezkrabbe" (which means "Indian Trapezoidal Crab").
Burrowing out of the water for reproduction. Live up to 3.000 meters high on the southern frontier of the Himalaya und can endure the winter there burrowed. People living there grab 'em out and eat 'em. Pests in rice fields, feed on roots and leaves.
Specimen found in Bangladesh up to 51 mm (Carapax width; female: 52 mm), nocturne and omnivorous; feed on remnants of other crabs, molluscs, insects, vegetation and detritus, hunt small aquatic animals.
Propagation begins with the rainy season and they "lay eggs" at the end of spring. In dry times the female carry eggs and juveniles until it is wet enough for them and they all come clear. In the dry season they dig burrows in clay near the water, which are sealed with mud.
In the habitat description it is stated that they live benthic and are abundant in shallow water bodies such as rice fields, canals and ponds, rarely in rivers.
Widespread in India, Bangladesh, Sri Lanka and Myanmar.
If caught for human and aquaculture feed, farmers eat it fried, and as medicine for asthma diseases. Nowadays, they are also known as poultry feed and fertilizer use.
Ecological Role: Important to maintain the aquatic balance as scavengers and hunters.
Status: common

Ah
Well done Ollie! I looked for a couple of those for a friend, 1-2 years ago. He had them some years ago and they are true freshwater and can be bred without salty water. Unfortunately I couldnt get hold of these animals.
I read in an article of Ng, that there are around 1300-1800 different kinds of true freshwater crabs in the world.
I do hope we will get to know a couple of them^^
Gruß!

I thought I recognised it. Yesterday I noticed "rusty crabs" on this UK price list, though they are listed as Uca sp. I guess they may be misidentified. They also have Panther River Crabs and Matano Purple River Crabs, Im guessing they would be Paratelphusa pantherina and Syntripsa matannensis or flavichella?
http://www.tropicalfishfinder.co.uk/dbim...ST(37).xls
If they still have them I'll be ordering at least some of the Panther River Crabs, and maybe some of the other species.
