Notes: Neodeightonia planchoniae and N.arengae introduced by Jayasiri et al.(2019) and Xiong et al. 2022, respectively, are reduced to synonymy under N. palmicola . According to the phylogenetic analyses in this study, isolates of N. palmicola , N. planchoniae and N. arengae clustered together in a monophyletic clade supported with high ML-BS/PP values ( Figure 4 ). The ex-type culture of N. palmicola (MFLUCC 10-0822) has the following nucleotide similarities with the sequences of the ex-types of N. planchoniae (MFLUCC 17-2427) and N. arengae (ZHKUCC 21-0074). On ITS: 99.00 % (496/501, including 2 gaps) and 99.60 % (499/501, including 1 gap), respectively. On LSU: 99.16 % (473/477, all incompletely specified bases) and 100 % (477/477), respectively. On SSU: 96.93 % (774/806, including 2 gaps and 16 incompletely specified bases) and 99.75 % (802/804, all gaps), respectively. No tef1 sequence data is available for the ex-type strain of N. palmicola (MFLUCC 10-0822), though ITS and tef1 are the most important loci to separate species within most genera of Botryosphaeriaceae ( Phillips et al. 2013) .

FIGURE 4. Phylogenetic tree of Neodeightonia generated from BA inference based on combined ITS and tef1 sequences. ML bootstrap support values (ML-BS ≥ 50 %) and Bayesian posterior probabilities (PP ≥ 0.85) are shown at the nodes. Strains with type status are indicated in bold font, the isolates from this study are presented in brown typeface and species are delimited with coloured blocks. The last accepted species names are noted after the strain number in quotation marks where species were synonymised in this study. The scale bar represents the expected number of nucleotide changes per site. The tree was rooted to Botryosphaeria corticis (CBS 119047) and B. dothidea (CBS 115476).
