“
Candidatus
Hepatoplasma crinochetorum” Ps is an extracellular symbiont residing in the hepatopancreas of the terrestrial isopod
Porcellio scaber
. Its genome is highly similar to that of the close relative “
Ca.

Armadillidium vulgare
. However, instead of a clustered regularly interspaced short palindromic repeat (CRISPR)-Cas system, it encodes a type I restriction modification system.
