Unikaryon nomimoscolexi n. sp. was examined ty electron microscopy fro
m material collected in Senegal (West Africa). It parasitizes adult of
Nomimoscolex sp. (Cestoda) from the gut of the freshwater fish Clarot
es laticeps. The microsporidium is parasitic in parenchymal cells. All
live cycle stages have isolated nuclei. Merogony and sporogony take p
lace in direct contact with the host cell cytoplasm and ultimately giv
e rise to unikaryotic sporoblasts and spores. The sporogony is disporo
blastic. The spores are ovoid ant measure, in thin sections, 3.43 +/-
0.4 x 1.51 +/- 0.18 mu m. The polaroplast has an anterior lamellar par
t and a posterior vesicular part. The polar tube is isofilar and is ar
ranged in 6 to 8 coils.
