Recent redefinition of Lophoziaceae has led to many nomenclature and taxonomic changes but several problems remains. Here we discuss and make the necessary new combinations for Lophoziopsis longidens subsp. arctica, Lophoziopsis pellucida var. minor, Heterogemma patagonica and Trilophozia quinquedentata var. asymetrica.
A number of new synonyms are proposed. Lophozia handelii is shown to be a synonym to Lophozia pallida and the species is treated separate from Lophozia guttulata.
Four problematic names in Lophozia (Lophozia groenlandica, Lophozia murmanica, Lophozia confertifolia and Lophozia longiflora) are discussed and a conspectus of the genus is given.
