Ultrastructure and development of Nosema podocotyloidis n. sp. (Microsporidia), a hyperparasite of Podocotyloides magnatestis (Trematoda), a parasite of Parapristipoma octolineatum (Teleostei).
Bottom Line: The polaroplast is divided into two regions: an outer electron-dense cup with granular content and lacking lamellae and an internal region, less electron-dense, composed of irregularly arranged sacs.The posterior vacuole, with an amorphous electron-dense content, is present.The new species is compared with other species of Nosema from trematodes.

Mentions: The mature spores were broadly oval (Fig. 4A). In thin sections, the spore dimensions calculated were 3.6 (3.1–4.0) × 2.58 (1.8–3.3) μm (n = 25). The diplokaryon was found in the posterior part of young spores (Fig. 3D) but it was not clearly visible in mature spores.Figure 4.
