†family Dolichometopidae Walcott 1916 (trilobite)

Trilobita - Corynexochida - Dolichometopidae

This has gotten effed up because the eponymous subfamily was entered later, with subsequent opinions elevating it to a family. So, it's now cut off from everything.

Alternative spelling: Dolichometopinae
