Three new Neotropical land planarians (Platyhelminthes, Tricladida, Geoplaninae) from the Brazilian Atlantic forest are described. Obama apiguara Oliveira, Almeida & Carbayo sp. nov. presents glandular fossae opening through dorsal epithelium, a structure not documented previously among land flatworms. Paraba tata Bolonhezi, Lago-Barcia & Carbayo sp. nov., is characterized by a prostatic vesicle horizontal with an inconspicuous bifurcate portion, a penis papilla as long as male atrium and a female genital duct projected from the postero-dorsal section of the female atrium. The third new species is distinctive in the extraordinarily thick muscle surrounding the prostatic vesicle, a finger-shaped penis papilla, and a dilated female genital cavity. These attributes stands the species apart from all members of Geoplaninae and Piima ata Carbayo gen. et sp. nov. is proposed.
