Costellariidae sometimes called the "ribbed miters" is a taxonomic family of minute to medium-sized predatory sea snails, marine gastropod mollusks.

Latiromitra (from family Ptychatractidae) has been found to be closely related to Costellariidae in the molecular phylogeny analysis by Fedosov & Kantor (2010).

[1][clarification needed] The shell ranges from small to medium-sized, with an elongate shape that is typically fusiform, elongate-fusiform, or turriform.

The shell often features a high spire, a very narrow aperture, and a well-developed siphonal canal.

[4] Species of this genus are found in the tropical and temperate waters of the Indo-Pacific, usually at depths between 0 mm and 200 m. [1] Genera within the family Costellariidae include: carnivorous.
