A redescription of Protoopalina pingi Nie, 1935 is presented in this paper to complete Nie’s description at both light and scanning electron microscope levels. These organisms were collected from the recta of the frogs Hylarana guentheri Boulenger, 1882 and Pelophylax nigromaculatus Hallowell, 1861 from Jialing River, Sichuan Province and Honghu Lake, Hubei Province, respectively, in China. This is the first record of its occurrence in H. guentheri and P. nigromaculatus. The body of P. pingi is elongated and somewhat spindle-like in shape, slightly narrowed and bluntly rounded at the anterior extremity, while the posterior end is tapering or sharply pointed. The body surface is thickly flagellated, with the caudal tip being barren. The falx, located at the margin of the anterior end, is composed of a narrow band of kinetosomes. Four round or oval-shaped nuclei, usually arranged in a straight line, are situated in the middle region of the body. Comparisons are made between P. pingi and its congeners.
Résumé
Une redescription de Protoopalina pingi Nie, 1935 est présentée dans cet article, pour compléter la description de Nie par la microscopie photonique et électronique. Ces organismes ont été recueillis à partir du rectum des grenouilles Hylarana guentheri et Pelophylax nigromaculatus, respectivement de la rivière Jialing dans la province du Sichuan et du Lac Honghu dans la province du Hubei, en Chine. C’est la première mention chez H. guentheri et P. nigromaculatus. Le corps de P. pingi est allongé et fuselé, légèrement rétréci et grossièrement arrondi à l’extrémité antérieure, tandis que l’extrémité postérieure est effilée ou très pointue. La surface du corps est fortement flagellée, mais la pointe caudale est nue. La faux, situé sur la marge de l’extrémité antérieure, est composée d’une bande étroite de cinétosomes. Quatre noyaux ronds ou ovales, généralement disposés le long d’une ligne droite, sont situés dans la région médiane du corps. Des comparaisons sont faites entre P. pingi et ses congénères.
