In order to assess the phylogenetic relationships and taxonomic position of Tanacetum semenovii Herder (Compositae, Anthemideae), a molecular-phylogenetic analysis based on nrDNA ITS sequences of nine representatives of the subtribe Handeliinae and 26 species of three other subtribes (Anthemidinae, Artemisiinae and Matricariinae) of the tribe Anthemideae was conducted. The central Asian endemic T. semenovii Herder was found being unrelated to members of the genus Tanacetum L (subtribe Anthemidinae) and sister to a clade formed by three representatives of the genus Richteria Kar. & Kir. of subtribe Handeliinae. Due to the close relationship of the T. semenovii to the Richteria species in a well-supported clade (PP = 1.0, BS = 78), which is supported by morphological features, the inclusion of T. semenovii in the genus Richteria and the new combination Richteria semenovii (Herder) Sonboli & Oberpr. is proposed.
