Maximum likelihood phylogenetic tree topology based on the COI dataset. Numbers on branches indicate support values (posterior probability/bootstrap). Scale bar: substitutions per nucleotide position. Note: the COI sequences of M. brandi sp. nov. MTP LS 3136 (SAMN15061113), M. brandi sp. nov. MTP LS 2864 (SAMN15061091) and M. sp. 34 MTP LS 2041 (SAMN15061043) are extracted from deposited transcriptomes (Brand et al. 2022a).
