The species name is a noun in apposition derived from the Latin for “scimitar” in reference to the strongly recurved and elongate dactyli of the posterior pairs of pereopods of the male.

|

We propose the new Japanese name Tsumenaga-kani-no-hana-chochin which refers to elongate dactyli of the male (“Tsumenaga” means “long claws”) and appearance of the female on the host (“hana-chochin” means “snot bubble”).
