Abstract
AbstractParamecium (Ciliophora, Oligohymenophorea) is a good model to study ciliate biogeography. Extensive sampling mainly in northern hemisphere has led to 16 valid morphological species description thus far. However, a majority of hard‐to‐reach regions, including South East Asia, are underinvestigated. Our study combined traditional morphological and molecular approaches to reveal the biodiversity of Paramecium in Thailand from more than 110 samples collected in 10 provinces. Representatives of seven morphological species were identified from our collection, including the rare species, such as P. gigas and P. jenningsi. Additionally, we detected five different sibling species of the P. aurelia complex, described a new cryptic species P. hiwatashii n. sp. phylogenetically related to P. caudatum, and discovered a potentially new genetic species of the P. bursaria species complex. We also documented a variety of bacterial cytoplasmic symbionts from at least nine monoclonal cultures of Paramecium.
