Orders

Orders

Billingsellida

An order that contains the suborder Clitambonitidina (and others?) .

Orthotetida

An order or superfamily that includes the Chilidiopsoidea.[2] Ontogeny given by Bassett and Popov (2017), resembling that of Kutorginides.[2]

Believed to be sister to Strophomenides, = Strophomenida + Billinsellida + Productida.[3]

Includes the Chileids (e.g. Coolinia).
