摘要: A revision of the cladistic analysis presented by Rodriguez and Pereira (1992) for species genus Fredius Pretzmann, 1967 (Pseudothelphusidae), was carried out using additional new homologies to obtain a more robust cladogram. The tree obtained differs from previous one in clustering species, but area cladogram confirms theory on plausible evolution group Guianan lowlands South America, between Orinoco Amazon rivers. is described Colombia, extending considerably range into upper basin. key all given.
