Zyzzyxdonta alata is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Endodontidae.

The name, given to the snail by malacologist Alan Solem, is the last word in many species dictionaries, just after Zyzzyx; however, they both, in fact, precede Zyzzyzus.

The postnuclear whorls have widely spaced radial ribs which protrude into hollow, winglike structures at the carinated periphery.

The body whorl has a protruded, keeled periphery, not descending more rapidly, with a distinct subperipheral sulcus.

The apertural barriers consist of three parietals, a single columellar one that slants downwards, and three long palatals.
