Aloina scindulosa M.J.Cano, J.A.Jiménez & M.T.Gallego isdescribed and illustrated as a new moss species from four localities in the Monte Desertarea of Argentina. It is distinct from all other members of the genus in the combination ofits lingulate leaves with unbordered margins, rectangular and slightly sheathing leaf bases,leaves ending in a long, hyaline, papillose hair-point near the leaf apex, the costa scarcelydifferentiated, in cross-section with no stereids, and the upper and middle laminal cells andcostal surface dorsally prorate in the upper midleaf. Possible confusion with other species ofthe genus is discussed. A key to the South American species of Aloina is provided.
