Abstract A new species of Pseudotrypanosoma, P. elphinstonae sp. n., is described which is symbiotic within the hindguts of the rhinotermitid termites Schedorhinotermes secundus and S. intermedius. P. elphinstonae possesses most of the features of the genus: 4 anterior flagella, prominent costa and recurrent flagellum forming an undulating membrane and simple bean-shaped parabasal body. The mastigont complex is of similar composition and arrangement to other trichomonads but the pelto-axostylar complex is greatly simplified being composed of a single layer of microtubules which do not over lap and cannot be distinguished into separate structures. The undulating membrane is much smaller than in related species; the costa is smaller and simpler and there are no microtubular bundles connecting it to the recurrent flagellum. Comparison of the ultrastructure of P. elphinstonae sp. n. with that of P. giganteum demonstrated that P. elphinstonae sp. n. in addition to being much smaller in size had a correspondingly simper ultrastructural organisation lacking several organelles which characterise the latter species.
