Morphology | Morphometrics
(total): 0. Gill opening reduced to a pore located in the membrane above the opercle. Gill membranes fused to the body and isthmus. Superior trunk and tail ridges continuous, inferior trunk and tail ridges discontinuous, lateral trunk ridge confluent with inferior tail ridge. Brood area of male located under trunk.
