Indusiella, previously known from North America (Alaska), central Asia and North Africa (Chad), is reported for the first time for South America. A new species, Indusiella stellata, is described based on one specimen collected from Potosí Department in Bolivia. In addition, I. thianschanica is reported for the first time from Argentina and Bolivia. The new taxon is distinguished from I. thianschanica by its immersed and gymnostomous capsule, leaf costa without dorsal stereids and 8–20 guide cells in (2–)3–4 layers in the basal leaf region, and stems without a central strand. Both species are described and illustrated. The description of Indusiella is reëvaluated and a key to the species of the genus is provided.
