Alternate Title

A New Shrimp Host for Parabopyrella lata (Nierstrasz and Brender à Brandis, 1929) (Crustacea: Isopoda: Bopyridae) from the Florida Gulf Coast: A Novel Host-Parasite Relationship or a Case of Mistaken Identity?


Identification of a bopyrid isopod found on a specimen of Lysmata wurdemanni (Gibbes) showed that it was not conspecific with the only known bopyrid parasite found on that host, Parabopyrella mortensi (Nierstrasz and Brender à Brandis, 1929). Instead, it is identifiable with a congeneric species, Parabopyrella lata (Nierstrasz and Brender à Brandis, 1929 ), formerly known only from alpheid shrimp hosts. A brief discussion of the implications of this finding on the question of level of host specificity is given, and evidence suggesting an accidental occurrence of the parasite on the host, rather than a successful host switch.
