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.

Class Poseidoniia

Etymology: [Po.se.i.do.ni'i.a] N.L. fem. n. Poseidonia, referring to the type genus Poseidonia; -ia, ending to denote a class; N.L. neut. pl. n. Poseidoniia, the Poseidonia class
Nomenclatural type: Genus Poseidonia
Description: The description is the same as for Poseidonia gen. nov. with the following additions; Poseidoniia class. nov. comprises the type order Poseidoniales ord. nov. and order Marine group III (MGIII).
Classification: Archaea » “Poseidoniota” » Poseidoniia

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.
Classification: Archaea » “Poseidoniota” » Poseidoniia » Poseidoniales » Poseidoniaceae

Family Thalassarchaeaceae

Etymology: [Tha.las.sar.chae.a'ce.ae] N.L. neut. n. Thalassarchaeum, referring to the type genus Thalassarchaeum; -aceae, ending to denote a family; N.L. fem. pl. n. Thalassarchaeaceae, the Thalassarchaeum family
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.
Classification: Archaea » “Poseidoniota” » Poseidoniia » Poseidoniales » Thalassarchaeaceae

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 alphae^Ts
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 betae^Ts
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.
