Resumo: The genus Travassiella Rego & Pavanelli, 1987 comprises only one species, T. avitellina Rego & Pavanelli, 1987; characterized by these authors on the basis of absence of vitelline follicles. In this study, the presence of cortical vitelline follicles in this species is confirmed after de Chambrier and Vaucher (1999); the redescription was performed for the first time based on type and new material collected from Argentina, Brazil and Paraguay. Travassiella is confirmed as a valid genus, and compared to other genera of the subfamily Zygobothriinae. T. avitellina is characterized by: (1) the presence of gland cells posteromedially to suckers; (2) the particular distribution of vitelline follicles, forming lateral arches; (3) uterine primordium cortical, growing into medulla and forming a sac-like uterus; (4) eggs, irregularly oval, outer envelop with excrescences and two digitate lappets in one of the poles.
