  3. Gill opening restricted to a small, elongate, tube-like opening adjacent to pectoral-fin base
  4. A single hypural plate emanating from a single complex half-centrum
  5. Ventralmost pectoral radial considerably expanded distally
  6. Eggs spawned in a double scroll-shaped mucous sheath
  7. Posteromedial process of vomer emerging from ventral surface as a laterally compressed, keel-like structure

  11. Proximal end of hypobranchials II and III bifurcate
  12. Interhyal with a medial, posterolaterally directed process
