The Rhabdoweisiaceae are a small to medium-sized family in the Dicranales, centred on the predominantly northern hemisphere genus Rhabdoweisia. Brotherus recognised it as a subfamily within the Dicranaceae, and included only three genera: the type genus, the widespread Amphidium, and the poorly known Philippine Rhabdoweisiella. Modern Floras have variously recognised the family or subsumed it within the Dicranaceae. In recent years the family has received wider recognition and has been expanded using molecular evidence to include as many as 15 genera. Three genera of Rhabdoweisiaceae, excluding the type genus, are accepted in the New Zealand Flora: Amphidium, Dicranoweisia, and Holodontium. Amphidium, with two species here, is widely distributed in temperate and cooler parts of both hemispheres. In part because of its lack of a peristome, its affinities have been controversial for many decades and will probably continue to be so. Dicranoweisia is also distributed widely in temperate to cool parts of the northern and southern hemisphere, but it also occurs on tropical mountains; one species is widespread in N.Z. Holodontium is probably monotypic. It exhibits a characteristic subantarctic distribution but extends into the South American tropics at high elevations in the Andes. It is known in N.Z. only from a few high elevation sites on the South I.
