3 Crustacean ID's from Lembeh - Sulawesi

I have 3 crustacean ID's from Lembeh in Northern Sulawesi that that I need some assistance on.

Crab found on night dive in 5 metre water - length was approximately 7 cm.

This small shrimp was living in a long skinny tube/barrel sponge. About 3cm long. It also looks like its carrying eggs.

This small shrimp was found near an anemone. It looks similaer to Percilimes holthusi however its got red markings on it which I haven't seen before. Approximately 2cm long.

Any help would be appreciated! Otherwise I'm going to have start searching through crustaceans ID books in the library and I really don't want to do that!

cheers,

Dave

The first one is Cyclocoeloma tuberculata - the striped legs & those flat anemones are diagnostic. The second is Periclimenaeus gorgonidarum I think. That's only the second I've seen of it outside a sponge and a really fine one. Periclimenes holthusi is getting split into a number of species. This particular one is in the Japanese crustacean books as a provisional species. One of the new ones is P. kobayashii. It's similar to this but it has one or more thin vertical lines & not as many red spots.

I think the third one may be what I have seen described as P. sarasvati. (latin is very close to the name Balinese goddess of art) maybe just a coincidence.

I thought this one was P. sarasvati:

I'll dig up the original publications at work & check.

Hi Leslie/Marli,

Thanks for the assistance on the ID's, much appreciated. I'm still digging through my Sulawesi pics so might be posting some more ID's shortly!

cheers,

The Periclemenes ids seem to be really mixed up. Edge of reef has this as P. holthuisi:

Which looks like your critter. I was told (can't even remember which scientist, probably Dr. Mary Wickstein, but I wrote notes in my reference about it) that P. holthuisi is most often misidentified, and that it is free living, as opposed to living with anemones. Usually the ones identified as P.holthuisi are P. tosaensis and P.sarasvati.

Too many purple spots, I say! OK, just noticed I have changed one name in my reference that looks like yours from Periclimenes sp. to P. holthuisi.

The variation in these in terms of colour just adds to the confusion, but the red spots and colorful tail are mentioned as characteristics.

Just call 'em all Periclimenes sp. and be done with it!

Cheers,

Marli

Dave - corrected ids from Sammy DeGrave (many thanks). My face is quite red about the first shrimp but I think I was safe with the second one......

"Periclimenaeus gorgonidarum is Anchistiodes sp., different family!! I say sp., as opinion differs how many species in Pacific one or five, and all based on small differences in leg spination etc.

Second one I would say is Periclimenes speciosus or close to that. Recently described and I have got them in my Sulawesi samples. The big blue dot on the uropod is characteristic, but it does differ slightly from the photo which Okuno gives, saddle is slightly different."

Anchistioides spp (family Anchistioididae) can be recognized by the high, straight-forwardly projecting rostrum

Leslie should have a photo of the Caribbean Anchistioides, it's quite common in Bocas del Toro

we got one here in Utila

Okay, I just checked and I do have one from Bocas. Lab shot of course, nothing that people here would appreciate! But I can see the difference in rostrum size & shape between Anchistioides and Periclimeneaeus, thanks for the advice.
