Molecular tree, based on the DNA sequences of 16S rRNA. The sequences were aligned using Clustal Omega and the neighbour-joining method constructed the tree. Numbers at branches indicate bootstrap values. The sequences of Cirolanidae (Excirolana hirsuticauda Menzies, 1962, MK898194) 16S RNA was used as the outgroup. Evolutionary analyses were conducted in MEGA 11. B. jamesi (NCBI Acc. Nos. KX417641, KX417643 and MZ029589), B. kensleyi (OQ865220, OQ865221 and OQ865222), B. yucatanensis (MZ042927) and B. giganteus (MG229477, MG229478 and MG229479.
