Phillips et al. 2012 (http://dx.doi.org/10.3767/003158512X658899) placed Diplodia alatafructa in synonymy with the earlier name D. pseudoseriata. These species belong in a single clade within Diplodia, although there is some genetic variation within that clade. Based on btub and TEF, the type isolates of D. pseudoseriata, D. alatafructa, and D. insularis are all in the D. pseudoseriata complex, as are isolates identified as D. pterocarpi. Btub sequences distinguish quite well the types of D. pseudoseriata, D. alatafructa and D. insularis, and the D. pterocarpi isolates. TEF does not distinguish D. pseudoseriata and D. alatafructa well, but the other species are distinct. Later authors (e.g. Zhang et al. 2021, https://doi.org/10.3767/persoonia.2021.46.03; Bezzera et al. 2021, https://doi.org/10.3390/plants10030492) have followed the D. pseudoseriata species complex concept of Phillips et al. (2012).

Based on btub and TEF sequences, ICMP 14110 belongs in the D. pseudoseriata species complex. The btub sequence from ICMP 14110 is very close to the accessions identified as D. pterocarpi, but their TEF sequences differ. Based on TEF sequences, ICMP 14110 is genetically very close to a specimen from Acacia in Queensland, BRIP 52819 (GenBank MH102230); a btub sequence is not available for BRIP 52819. Note that the New Zealand isolate ICMP 14110 was collected from a dead twig in vegetation restoration site that includes naturalised Acacia.
