The Visean, the second age of the Mississippian, contains four conodont biozones, two of which are named after Lochriea species:

• the zone of Lochriea nodosa
• the zone of Gnathodus bilineatus
• the zone of Lochriea commutata
• the zone of Pseudognathodus homopunctatus

The Serpukhovian, the third or youngest age of the Mississippian, includes three conodont biozones, one of which is named after Lochriea species:

• the zone of Gnathodus postbilineatus
• the zone of Gnathodus bollandensis
• the zone of Lochriea ziegleri
