    Notes:
    • ⊕ Emendation accompanied by the proposal of 1 new species in the genus.
    • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Names but not taxa can be validly published. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details.
