New record of five ciliate species from temporary ponds on a grass lawn

We identified 22 ciliate species, including five unrecorded ciliate species, from temporary ponds on a grass lawn. The five unrecorded species are as follows: class Nassophorea - Pseudomicrothorax agilis Mermod, 1914, Nassula exigua Kahl, 1931, class Colpodea - Cyrtolophosis mucicola Stokes, 1885, Maryna ovata (Gelei, 1950) Foissner, 1993, and class Spirotrichea - Meseres corlissi Petz & Foissner, 1992. Most of these 22 ciliate species disappeared from a raw culture within a few days (probably encystment), and a few cells were available from some species that resulted in incomplete identifications (e.g., genus-level). About the unrecorded five ciliate species, they are small in size (<60 ㎛ in vivo), and two of them live in a hyaline dwelling-tube, which is easily deserted by a cell with a stress. Their taxonomic classification is summarized as three classes, five orders, five families, and five genera. Here, we provide brief descriptions, micrographs of their morphology, and some remarks.
