Abstract. A plcistophorid microsporidian is described from marron, Cherax tenuimanus (Smith). The parasite is polysporous, forming eight, 16, 32 or 64 ovoid spores in persistent, two‐layered mcrontogcnctic sporophorous vesicles. Nuclei remain isolated throughout merogony and sporogony. The sporophorous vesicle forms from the amorphous coat surrounding meronts, which thickens and condenses into two layers during sporogony. The parasite is placed in Vavraia Weiser, 1977, and named Vavraia parastacida sp. nov.
