Abstract
FIGURE 9. Semi-schematic drawing of a valvar view of the spore of Myxobolus insignis, a parasite of the freshwater fish Semaprochilodus insignis from Amazonian fauna showing the morphologic characters, such as the spore shape and size, two equal polar capsules with six oblique polar filament coils, and the binucleated sporoplasm with several sporoplasmosomes. The spore wall is surrounded by a thick layer of electron-dense anastomosed fine microfibrils.
