REMARKS
A female parasite was figured in color by
Ng & Ahyong (2022)
and appears to be a new species; unfortunately, the specimen could not be located in the ZRC during this study. There is evidence of parasitism on the host, as there are at least three small puncture marks on the left side of pleomeres 1 and 2, indicating feeding by the female bopyrid.
The host (ZRC 2017.1020) as seen in
Ng & Ahyong (2022
: fig. 75A) appears to have any asymmetrical carapace with the right side swollen, suggesting branchial parasitism by another species of bopyrid; however, we have seen the specimen and it is not parasitized branchially.
