|Apertural view of a shell of Antarctoneptunea benthicola|
Antarctoneptunea benthicola is a small-to-medium-sized species of marine snail in the genus Antarctoneptunea, the shell reaches 100 mm in height and 40 mm in diameter.
The species was formerly recognised as Penion benthicolus, but evolutionary trees based on mitochondrial and nuclear ribosomal DNA sequence data, as well as geometric morphometric analysis of shell shape and size, indicate that the species belongs to Antarctoneptunea.
A subspecies, Penion benthicolus delli Powell, 1971 was formerly recognized, but this taxon has since been demonstrated to be indistinguishable from other P. benthicolus based on shell morphology.
