Aegopinella subnitens is an extinct species of small land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae, the glass snails.
[1] (Original description in Latin) The shell is distinctly umbilicate and depressed, with a flat and glabrous surface.
It is shiny and consists of 4.5 convex whorls that gradually increase in size, with the body whorl slightly expanded anteriorly.
The aperture is ovate-lunate, and the peristome is simple and acute, with the apertural lip being non-callous.
[2] Fossils of this extinct species were found in late Miocene strata in Baden-Württemberg, Germany and in southern Poland.
