Abstract

Three strains of the genus Diaporthe were isolated from different plant hosts in south-western China. Phylogenetic analyses of the combined ITS, β-tubulin, tef1 and calmoudulin dataset indicated that these strains represented three independent lineages in Diaporthe. Diaporthe millettiae sp. nov. clustered with D. hongkongensis and D. arecae, Diaporthe osmanthi sp. nov. grouped with D. arengae, D. pseudomangiferae and D. perseae and Diaporthe strain GUCC9146, isolated from Camellia sinensis, was grouped in the D. eres species complex with a close relationship to D. longicicola. These species are reported with taxonomic descriptions and illustrations.

Keywords: Diaporthe; 2 new taxa; phylogeny; taxonomy.
