Conorbidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.^[2][3]

In 2011, Bouchet, Kantor et al elevated the subfamily Conorbiinae (at that point it was placed in the family Conidae) to the rank of family. This was based on anatomical characters including the (radular teeth and the shell characters) plus a dataset of molecular sequences of three gene fragments ^[1]

Description

The shell can have different forms: from squatly conical to elongated or even biconical. There are no nodules on the shell, but cords may be present. The interior, including the columellar region, is substantially remodeled.

The spire in the fossil genus Conorbis is much elevated. Its outer lip is sinuous, forming an oblique posterior sinus.^[4]

Genera

• Artemidiconus da Motta, 1991
• Benthofascis Iredale, 1936
• † Conorbis Swainson, 1840 (fossil genus from the Eocene)
