A cladistic analysis of a group of 19 species is presented. These species are distributed in 4 closely related genera of Leptohyphidae (Allenhyphes, Yaurina, Lumahyphes and Traverhyphes), that belong to a highly supported monophyletic group. Three subgenera of Traverhyphes are proposed to accommodate some new species and combinations. Traverhyphes (Traverhyphes) is restricted to T. (T.) indicator, T. (T.) pirai and T. (T.) chiquitano sp. n. Traverhyphes (Mocoihyphes)Allenhyphes, Yaurina, Lumahyphes and Traverhyphes), that belong to a highly supported monophyletic group.
