Abstract

We present a description of the new species Rhynchostegium occultum from central Chile, including illustrations, a distribution map, and preliminary molecular data that supports its taxonomic placement. The new taxon is restricted to coastal relict forests of central Chile. An overview of the Chilean taxa of Rhynchostegium, and a key for local species are also provided. The new combination Rhynchostegium corralense, and new synonyms for Rhynchostegium acanthophyllum and for Cratoneuropsis chilensis are proposed. Oxyrrhynchium hians is newly reported for Chile, apparently being a recent introduction. Lectotypes are selected for Hypnum corralense, Hypnum acanthophyllum, and for Rhynchostegiella acanthophylla var. robusta.
