Euparthenia
Encyclopedia
Euparthenia is a subgenus
of very small sea snail
s, pyramidellid
gastropod mollusks, or micromollusk
s in the subfamily Turbonillinae
.
The name Euparthenia is a replacement name for Parthenia Lowe, 1841 not Robineau-Desvoidy, 1830.
The genus Euparthenia contains both Recent and fossil
species.
(in English translation) is as follows: "Shell non-umbilicate, moderately turriculate, with spiral rings and ribs; columellar fold distinct. Kleinella (E.) bulinea (Lowe). A couple of species in the Mediterranean Sea and Atlantic Ocean."
The description of the type species by Richard Thomas Lowe
(1841) reads:
"PARTHENIA BULINEA. P. testa subcylindaceo-attenuata, oblongiscula, juniore ovato-tereti: anfractibus planis, elegantissime reticulato-cancellatis, striis spiralibus crebris aequidistantibus, transversas aequidistantes decussantibus; sutura distincta impressa: columella postice torta, uniplicata. a. subventricosa."
sensu lato, they are most likely to be ectoparasites.
Subgenus
In biology, a subgenus is a taxonomic rank directly below genus.In zoology, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the Tiger Cowry of the Indo-Pacific, Cypraea tigris Linnaeus, which...
