Achaeus japonicus ?

[Wisnu]

I took this picture in Lembeh. I though a pair of orangutan crabs (Achaeus japonicus). But when I look further detail, I am not sure.
To my knowledge, Achaeus japonicus has red eye, oval head, body and arms are covered with long thick red hair.
The lower part I guess is Achaeus japonicus, having red eye, covered with thick hair although not red. Am I correct ?

The upper critter is red but has no hair - and no red eye. Here the better picture.

THey are not orangutan crabs.
Orangutan crabs have that long flowing hair, red eyes, and usually live in anemones.

I don't know though exactly what species they are. There are so many species
of undescribed crabs.
nice finds btw

Matt,
Thanks for the response
How about the white one? do you think not orangutan crab
it has red eyes, thick hair but not red.
I have checked in Crustacea guideline by Debelius but still can't find the answer.

I'm not familiar with that particular crab but I'd bet on it being one from the genus "oncinopus", possibly oncinopus aranea (see illustration on http://species-identification.org/species.php?species_group=crabs_of_japan&id=831&menuentry=soorten).

I googled macropodia - still not very sure.
Tony Wu in his website name it as "king kong crab"

We crossed posts. I edited my response after checking the database. Macropedia aren't native to indonesia. Check my previous post again.
