Peltospiroidea n. sp. East Scotia Ridge (nomen nudum) is an as yet undescribed species of deep sea peltospiroid sea snail from hydrothermal vents, a marine gastropod mollusk in the clade Vetigastropoda.
The first information about this species, under the name "Peltospiroidea n. sp." or "peltospiroid gastropod", was published on 3 January 2012. Peltospiroidea is the name of a superfamily of gastropods that was used in the taxonomy of the Gastropoda (Ponder & Lindberg, 1997). It contained the only extant family Peltospiridae (and some prehistoric gastropod families). However, the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005) does not use the name Peltospiroidea (in that system, the family Peltopiridae is placed within the Neomphaloidea).
As yet there is very little information available about this undescribed species. According to the published photo, the brown shell has rapidly expanding whorls and the length of the shell is about 2.5-3.0 cm.
Small limpets Lepetodrilus sp. East Scotia Ridge are sometimes found on the shells of this peltospiroid gastropod. Other marine fauna, such as actinostolid sea anemones (family Actinostolidae), crabs in the genus Kiwa, and the pycnogonid arthropod or "sea spider" cf. Sericosura, can be found living together with this species.
