Candidatus Rhabdochlamydia is a genus of intracellular bacteria; a separate family, Candidatus Rhabdochlamydiaceae, has been proposed for this genus. Candidatus Rhabdochlamydia species have not been cultured in vitro and have not been deposited in culture collections.
Two Rhabdochlamydia species have been characterized and validly proposed. Their ribosomal RNA genes are 96.3% identical. These gene sequences are 82%–87% identical to those of most Chlamydiales. These data and Rhabdochlamydia morphology indicate that these species will belong to the order Chlamydiales, class Chlamydiae, phylum Chlamydiae, domain Bacteria.
Candidatus Rhabdochlamydia porcellionis was identified in the hepatopancreas of the woodlouse Porcellio scaber (Crustacea: Isopoda).
The second Rhabdochlamydia species is Candidatus Rhabdochlamydia crassificans, which was identified in the cockroach Blatta orientalis (Insecta: Blattodea).
