Limpet-shaped shells, very simple in structure. The determination is based upon the anatomy, but also on the apex: « In having a long and narrow apical fold and a fused tip, the pseudococculinid protoconch is clearly different from the cocculinid one (Marshall, 1986). » – G. Haszprunar: “Anatomy and affinities of Pseudococculinid limpets (Mollusca, Archeogastropoda)”, Zoologica Scripta vol.17 (2), Oslo 1988, p.162.
 

Shell oval, sculptured with concentric wrinkles. Apex posteriorly placed. « The name characterizes the extremely developed copulatory organ and the abyssal habitat of the species included. » – G. Haszprunar: op. cit. p.177.
