Cyrtomaia micronesica is different than its closest relative (Cyrtomaia cornuta from New Caledonia) by shorter basal antennal spines, longer chelipeds, varied male meri and pleopod and a varied carapace.
This is a composite image of the 1st pair of pleopods and the outer branch (exopodite) of the right (animal's left) pair that came apart during the removal operation (each pleopod has an outer and an inner branch).
On males, the fourth pleopod is long and specialized for mating.
