[New data on Dicrocoelium hospes Looss, 1907: anatomy of the adult and life cycle. Preliminary paper (author's transl)].

The morphological and anatomical studies of Dicrocoelium hospes Looss, 1907, from Togo set off several differences with Dicrocoelium lanceolatum Rudolphi, 1819: shape and dimensions of the body, shape and disposition of the testes, shape, dimensions and location of the vitellaria, structure of the uterus coils. The first intermediate host is found, they are three species of Limicolaria, one of them being L. aurora. The cercaria is described, its chaetotaxy confirms the validity of species D. hospes. Two species of ants: Dorylus sp. and Crematogaster sp. may be the second intermediate host.
