    In this study, potential alternate hosts of the phytoplasma causing coconut lethal yellowing disease (CLYD) in Mozambique were investigated based on 16S rRNA and secA genes. The results reveal that the naturalized palm species, Elaeis guineensis and Borassus aethiopum are alternate hosts of CLYD phytoplasma in Mozambique. Based on the iPhyClassifier online software, the phytoplasma detected in B. aethiopum belongs to the 16Sr group XXII-A, which include ‘Candidatus Phytoplasma palmicola’ and ‘Candidatus Phytoplasma cocosnigeriae’. This is the first report associating ‘Candidatus Phytoplasma palmicola’ with wild naturalized palm species in the world. Key words: Alternate hosts, Borassus aethiopum, „Candidatus Phytoplasma palmicola‟, Elaeis guineensis, Mozambique, palm lethal phytoplasma phylogeny
