ABSTRACT. Lophozia ventricosa var. longiflora (Nees) Macoun is recorded for South Shetland Islands; this is the second report of the taxon for the Southern Hemisphere. Isopaches bicrenatus (Hoffm.) H.Buch is reported for the first time from Central America, in Dominican Republic. A new combination Isopaches pumicicola (Berggr.) Bakalin comb. nov. is proposed. Tritomaria mexicana Bakalin sp. nov. is described as new to science. The diagnostic characters of the new species include 2-lobed leaves with equal to slightly subequal lobes and 1-celled angular gemmae, the combination unknown in any other member of the genus.
