Aegopinella subnitens is an extinct species of small land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae, the glass snails.

Description

(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.^[1]
