Belonging to the family Caryophylliidae Dana, 1846, the genus Crispatotrochus Tenison–Woods, 1878 was described at the end of the 19th century to accomodate the species C. inortatus Tenison–Woods, 1878 collected off Port Stephens, Australia, which, as described by the author, differs from Ceratotrochus Milne Edwards and Haime, 1848, in being broadly adherent with very simple costae, having a broad and deep fossa, and having small septa (Tenison–Woods 1878). Known from the Miocene (Wells 1956) and with 13 Recent valid species, the genus Crispatotrochus is recorded worldwide and is characterized by having a ceratoid to turbinate solitary corallum, which is firmly attached through a robust pedicel; theca costate or porcellaneous; septa symmetry hexameral or decameral; pali absent, and columella fascicular and usually robust, composed of 2–30 twisted laths (Cairns 1991).
