Apologies, @thomaseverest I thought I had commented about this one... Now I realize I had never put my partial thoughts out at all.
The species japonicum has often been considered only a local form of M. lacustre, so it would surprise me if it ended up in a different genus (or even subgenus).
It was not included in the 2023 analysis of Bespalaya et al, but it was included in Lee & Ó Foighill, 2003.

Los desacuerdos no intencionados ocurren cuando un grupo padre (B) se adelgaza al cambiar un grupo hijo (E) a otra parte del árbol taxonómico, provocando que las Identificaciones existentes del grupo padre sean interpretados como desacuerdos con las Identificaciones existentes del grupo hijo cambiado.
Identification
La ID 2 del taxón E será un desacuerdo no intencionado con la ID 1 del taxón B después del intercambio de ancestros
Si el adelgazamiento del grupo padre provoca más de 10 desacuerdos no intencionados, deberías dividir el grupo padre después de intercambiar el grupo hijo para substituir las identificaciones existentes del grupo padre (B) con identificaciones con las que no esté en desacuerdo,
