SYNOPSIS Ultrastructure of both undifferentiated (promastigote and paramastigote) and differentiated (opisthomastigote) forms of Herpetomonas megaseliae is described. There is a posterior migration of the kinetoplast at the end of the exponential growth phase. The posterior extension of the flagellar pocket precedes migration of the kinetoplast. Opisthomastigotes have an electron‐translucent mitochondrial matrix in comparison with undifferentiated forms. The Golgi body changes from a stack of flattened sacs to an aggregation of vesicles. Several structures previously reported from Trypanosomatidae, e.g. subpellicular organelles, pellicular microtubules, membrane whorls, stored metabolic products, surface blebs, and an intraflagellar body are also present in H. megaseliae .
