Teinostoma obtectum Pilsbry & McGinty, 1945 is another member of a highly diverse family of micromollusks, the Tornidae. The Glossy Vitrinella reaches about 2.2 mm (about 0.09 inch) in diameter, and its shell is strongly depressed (flattened), with the spire (the top) covered with a glass-like glaze. The shell outline is rounded, and the base shows a prominent callus. Shell color is white. The illustrated shell was collected in 1996 on Sanibel, and later identified by Harry G. Lee.
