Type genus

Ophiernus Lyman, 1878a (type species: O. vallincola Lyman, 1878a ).

Diagnosis

Lateral arm plates without vertical striations, but with horizontally striated proximal band (under adjacent plate). Bristle-shaped accessory arm spines.

Lateral arm plates with several rib-like spurs on external proximal/internal distal band (where adjacent plates overlap). Arm spine articulations with weak lobes.
