shrimp identification

The attached shrimp photo was taken in Bali. Can anybody help in identifying exactly what species it is?

Look in the books for Sauron shrimp.

Thanks very much. I've now had a look an a few sites and can see that it is a Saron Marmoratus.

I think Sauron Shrimps are found only at Barad-dur in Mordor

Could be it be Saron sp.1 ?

Cheers,

Humann and Deloach in their new book "Tropical Pacific Reef Creature Identification" have this down just as one in a whole group they term Saron spp.. They comment: "This is a poorly studied group that awaits further research. At present individuals bearing numerous tufts of sensory hairs are categorized as Saron marmoratus. However, it is believed that the complex possibly contains several unique species. Similarly patterned individuals, displaying a variety of colors, have been roughly grouped together."

By the way, I've seen your particular shrimp termed a "stars and stripes shrimp".

Jim, which source is calling it "sp.1"?

I found a match in Kuiter and Debelius' "World Atlas of Marina Fauna" pg 135. It had images of specimens from the Philippines with the same markings as the OP's image.

Failed to find another reference of that particular designation though. My copy of the new Humann and Deloach book is in the post, really looking forward to reading it.

"Species 1", "species A", etc., are what we call provisional species names. Usually they're just designations given by the guide book's author for things they can't get names for. In that case you'll find the same species listed under different designations in different books.

If the provisional name is followed by a researcher's name such as "Alpheus sp. 12 Anker" or the book is by a specialist like Terry Gosliner then it means that a specialist recognizes the species as probably unique and undescribed.
