We found the ciliophoran protozoan Lagenophrys sp. to be symbiotic on the freshwater ostracod Cryptocandona sp., collected from Makkari, Hokkaido, Japan. In Japan, this is the third record of Lagenophrys and the first case from ostracods. We present a nucleotide sequence for the 18S rRNA gene (1,683 bp) from Lagenophrys sp. In an 18S maximum-likelihood tree that included 57 peritrichid sequences, Lagenophrys sp. grouped with the usconophryid Usconophrys sp.
