ABSTRACT
Taxonomic implications of the phylogeographic studies based on multilocus
sequencing of nuclear and chloroplast DNA regions of Syntrichia sarconeurum, long
considered to be Antarctic endemic moss species, are summarised. Molecular analyses
confirmed the conspecificity of Syntrichia sarconeurum with S. lithophila and
S. pygmaea. This taxonomic conclusion implies that the correct name for the species
in the genus Syntrichia is S. lithophila and S. sarconeurum is a new synonym of this
name. It is because S. sarconeurum takes priority from 2007, whereas S. lithophila
is based on Tortula lithophila which was validly published in 1906 and it is the next
earliest legitimate name at the rank of species to be used. Syntrichia sarconeurum,
as traditionally conceived, proved to be a heterogeneous taxon actually consisting of
two distinct species, namely S. lithophila and S. frigorideserticola nom. nov., which
is a new name for Sarconeurum antarcticum whose epithet is not available in Syntrichia.
Australian and New Zealand plants of Syntrichia with propaguloid leaf apices are
definitely distinct
from South American and Antarctic S. lithophila and S. frigorideserticola
and the correct name for them is S. abruptinervis comb. nov., based on Tortula abruptinervis.
