Small decorator crab, with spiny carapace and legs. Variable colour, with a pattern of white, orange and red lines reproducing the colour of the associated soft coral (Dendronephthya sp.). Carapace lenght 2 cm.
Impossible to confound. On soft corals it can live together with other species of the Majidae family (like Achaeus spinosus, Naxioides sp.) and porcelain crabs.
