Abstract

Examination of 4 Ozark cavefish, Troglichthys rosae, collected opportunistically during February 2020 from Benton County, Arkansas, U.S.A., revealed the presence of an unknown myxozoan (Myxobolus sp.) in the gall bladder of 1 fish and encapsulated metacercariae of Clinostomum sp. (“yellow grub”) in 2 hosts. One Ozark cavefish harbored 4 metacercaria and the other a single metacercaria. This is the first report of any parasite from T. rosae, a federally threatened species. We also provide a summary of parasites reported from members of the cavefish and swampfish family, Amblyopsidae.
