Balantidium grimi n. sp. is described from the rectum of the frog Quasipaa spinosa (Amphibia, Dicroglossidae) from Lishui, Zhejiang Province, China. The new species is described by both light microscopy (LM) and scanning electron microscopy (SEM), and a molecular phylogenetic analysis is also presented. This species has unique morphological features in that the body shape is somewhat flattened and the vestibulum is “V”-shaped, occupying nearly 3/8 to 4/7 of the body length. Only one contractile vacuole, situated at the posterior body, was observed. The phylogenetic analysis based on SSU-rDNA indicates that B. grimi groups together with B. duodeni and B. entozoon. In addition, the genus Balantidium is clearly polyphyletic.
Résumé
Balantidium grimi n. sp. est décrit à partir du rectum de la grenouille Quasipaa spinosa (Amphibia, Dicroglossidae) de Lishui, province de Zhejiang, Chine. La nouvelle espèce est décrite à la fois par microscopie photonique et électronique à balayage, et une analyse phylogénétique moléculaire est également présentée. Cette espèce possède des caractéristiques morphologiques uniques en ce que la forme du corps est quelque peu aplatie et que le vestibule est en forme de « V » et occupe près de 3/8 à 4/7 de la longueur du corps. Une seule vacuole contractile, située au niveau du corps postérieur, a été observée. L’analyse phylogénétique basée sur la petite sous-unité de l’ADNr indique que B. grimi forme un groupe avec B. duodeni et B. entozoon. De plus, le genre Balantidium est clairement polyphylétique.
