Zeidora is a genus of sea snails, marine gastropod mollusks in the family Fissurellidae, the keyhole limpets.^[1]

Description[edit]

The genus Zeidora was instituted by A. Adams in 1860, for the reception of two Japanese shells having the outer aspect of Emarginula and an internal shelf as in Crepidula.^[2]

The shell resembles Emarginula, with the margin of the aperture crenulated and anteriorly deeply fissured, but there is posteriorly an internal, flat, semilunar septum present, which distinguishes this genus from any other Fissurellidae.^[3]
