Alcadia gonavensis is a species of an operculate land snail, terrestrial gastropod mollusk in the family Helicinidae.
(Original description in Latin) The shell is globosely depressed, somewhat solid, and slightly shiny, with fine oblique striations visible under a strong lens. It is whitish or reddish in color. The spire is depressed and broadly conical. There are 5 whorls, slightly increasing in size, with the first 4 being almost flat and the body whorl rounded. The aperture is oblique and triangularly semi-oval. The columella is short, receding, and excavated, ending in a sharp tooth, and emitting a thin, well-defined callus above. The peristome is somewhat callous, slightly expanded, and separated by a notch and a small tooth on the columella.[1]
This species occurs in Haiti, Hispaniola.
