Type species
This is the type species (holotype) of the genus Neoralfsia.

Status of name
This name is of an entity that is currently accepted taxonomically.

Basionym
Myrionema expansum J.Agardh

Type information
Type locality: Veracruz, Mexico (Silva, Basson & Moe 1996: 573). Type: C (Yoshida 1998 Notes: According to Leon-Alvarez & González- González (2003: 613), the holotype of Ralfsia expansa (J. Agardh) J. Agardh [Agardh 1847, as Myrionema (?) expansum] was collected by Liebman from an unspecified area on the east coast of Mexico in Veracruz. The type specimen was sterile and an incomplete description of the taxon was published by Agardh in 1848.

Origin of species name
Participle A (Latin), expanded, spread out (Stearn 1973).

Homotypic Synonym(s)
Myrionema expansum J.Agardh 1847
Ralfsia expansa (J.Agardh) J.Agardh 1848

Taxonomic notes
According to León-Álvarez et al. (2014), the authentic N. expansa from the type locality is different from the entities that have been identified as that species from Japan and Malaysia and the latter specimens represent an undescribed species of a new genus for which new names must be given. - (13 Feb 2015) - Wendy Guiry

General environment
This is a marine species.
