, the new species lacks any trace of the three plumose setae on the posterior margin of the second exopodal segment of leg 1. However, it differs from all other species that share this character in the spine formula of the fourth leg exopod – which bears I, III spines rather than I, IV found in all other species lacking the leg 1 setae. This combination of characters is unique in the genus, and allows us to identify this species as new despite the incomplete state of the antennae and the lack of a male. It shares some other characters typical of the

An interesting character present in the new species is the striated ventral border extending around the lateral margins of dorsal cephalothoracic shield internal to the margin membrane. It is distinctly notched in the vicinity of the post-antennal processes. We infer that this border enhances attachment to the surface of the host. This striated border has not been discussed extensively but we note that it also occurs in
