Register list for 7 new names including Poseidoniales ord. nov.
Submitted by Rinke, Chris
Abstract
The register list covers the proposal of two type species; Poseidonia alphae (GCA_002505405.1) representing subgroup MG IIa and Thalassarchaeum betae (PSPG00000000) representing subgroup MG IIb. Based on these type species/genera, we further propose the families Poseidoniaceae fam. nov. and Thalassarchaeaceae fam. nov., the order Poseidoniales ord. nov. (formerly known as Marine Group II or MG II), and the class Candidatus Poseidoniia class nov.
Note that the term Candidatus used in the effective publication has been omitted from the register.

Order Poseidoniales
- Etymology
- [Po.se.i.do.ni.a'les] N.L. fem. n. Poseidonia, referring to the type genus Poseidonia; -ales, ending to denote an order; N.L. fem. pl. n. Poseidoniales, the Poseidonia order
- Nomenclatural type
- Genus Poseidonia
- Description
-
The description is the same as for Candidatus Poseidonia gen. nov. with the following additions; -ales ending to denote a order. Candidatus Poseidoniales ord. nov. was previously known as “Marine Group II” and comprises two families Candidatus Poseidoniaceae fam. nov. and Candidatus Thalassarchaeaceae fam. nov.

Family Poseidoniaceae
- Etymology
- [Po.se.i.do.ni.a'ce.ae] N.L. fem. n. Poseidonia, referring to the type genus Poseidonia; -aceae, ending to denote a family; N.L. fem. pl. n. Poseidoniaceae, the Poseidonia family
- Nomenclatural type
- Genus Poseidonia
- Description
-
The description is the same as for Poseidonia gen. nov. with the following additions. Poseidoniaceae fam. nov. was previously known as and “Group II-∝” and “Marine Group IIa”. Eleven genus-level clades I, J1, J2, J3, K1, K2, L1, L2, L3, L4, and Poseidonia (M) representing the rank of genera were assigned to this family. All members of the family were inferred to be marine, motile heterotrophs, encoding phototrophic and non-phototrophic lifestyles with a distribution from surface waters to the deep sea (1m-500m). Type genus: Poseidonia gen. nov.

- Nomenclatural type
- Genus Thalassarchaeum
- Description
-
Thalassarchaeaceae fam. nov. formerly Marine Group II (MGII) subgroup b, also known as MGIIb, is a family of the globally abundant marine order Poseidoniales.

Genus Poseidonia
- Etymology
- [Po.se.i.do'ni.a] N.L. fem. n. Poseidonia, named after Poseidon, the Greek god of the sea
- Nomenclatural type
- Species Poseidonia alphaeTs
- Description
-
Poseidonia named after Poseidon, the Greek god of the sea. Inferred to be of marine origin, a motile, aerobic, photoheterotroph, and able to ferment a wide range of carbohydrates with a focus on peptides. Highest abundances were recorded for surface waters (0-10m). Formerly identified as clade M.

Genus Thalassarchaeum
- Etymology
- [Tha.las.sar.chae'um] Gr. fem. n. thalassa, the sea; also the primeval spirit of the sea; ; N.L. neut. n. archaeum , (from Gr. adj. archaios -ê -on, ancient) archaeon; N.L. neut. n. Thalassarchaeum, the archaeon from the sea
- Nomenclatural type
- Species Thalassarchaeum betaeTs
- Description
-
Thalassarchaeum the archaeon from the sea. Inferred to be of marine origin, representing non-motile, aerobic heterotrophs containing phototrophic and non-phototrophic members. Formerly identified as clade O and now as genus O4 (this study). This genus name is proposed for continuity with the orthographically incorrect “Thalassoarchaea” suggested by [10.1038/ismej.2014.249] for low GC MGIIb fosmid-genomes. Type species: Thalassarchaeum betae.
