Abstract
A new psammobiontic Willemia species from Brazil is described and illustrated: W. zeppelini sp. nov. The phylogeny for all the 43 species of the genus Willemia is proposed comprising the new species and 8 species not included in D'Haese (2000) work. The new species is well defined with a unique Ant. III organ and one hr chaeta per anal valve among other characters. W. zeppelini is sister group to the buddenbrocki-group. An identification key for all known species of the genus is provided.
