Abstract
Cepedea longa Bezzenberger, 1904, collected from Fejervarya limnocharis (Amphibia, Anura, Ranidae) from Honghu Lake, Hubei Province, China in May–July 2016, is described at both light and transmission electron microscope levels. This is the first electron microscopic study of this species. Cepedea longa possesses a developed fibrillar skeletal system, composed of longitudinal fibrillar bands and transversal fibrils as well as numerous thin microfibrils dispersed in the endoplasm, which may play an important role in morphogenesis and offer some resilience to deformations of the cell. Longitudinal microfibrils are polarizing elements of kineties, bordering the somatic kineties on the left side and possibly responsible for kinetosome alignment. Two types of vesicles exist in the somatic cortex: globular endocytotic vesicles and flattened exocytotic vesicles. As to the nuclei of C. longa, a thick microfibrillar layer was observed to attach to the cytoplasmic face of the nuclear envelope. This fact suggests no necessary connection between the presence of this microfibrillar layer and the number of nuclei. In addition, some unknown tightly-packed microtubular structures in the nucleoplasm were observed for the first time in opalinids; neither their nature nor physiological significance is known. A detailed list of all reported Cepedea species is included.

Abstract
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.

Abstract
The morphology and cytology of two new opalinid species were studied using silver impregnation and fixation, which preserves the microfibrils. Both species, commensal on Acanthixalus spinosus, are host-specific. Light microscopy showed the existence of a posterior secant system in Opalina proteus n.sp. and its absence in Cepedea couillardi n.sp. (in agreement with the differences presently recognised between the two genera). At the ultrastructural level, however, both species present a posterior fibrillar zone that seems to be homologous with the secant system. This apparent contradiction may be explained by the fact that the secant system is visible under light microscopy only in O. proteus because its fibrillar zone is more developed than in C. couillardi. The life cycle of C. couillardi spans stages from the tadpole to the adult; in contrast, O. proteus completes its cycle before metamorphosis of the host.
