| Exopod unsegmented, with 2 long and 1 shorter unequal terminal aesthetascs, and 1 simple seta. |
| Plumose setae and aesthetascs are present on the peduncle, and simple setae on the antennular flagellum were noted, from stage I larvae to adults. |
| As coconut crabs live on the land, the aesthetascs on their antennae are shorter and blunter than those of other crabs and look more like those of insects. |
| The long antennular aesthetascs and the long plumose natatory setae of the first and second maxillipeds have been drawn truncated. |
