It is a very small worm with two pairs of eyespots. The hooks are thin with a protruding “heel” on each hooklet. Dorsal anchors are relatively small, and the dorsal connective bar has widened ends, slightly curved backward. The ventral anchors have prominent roots and a recurved point. The copulatory complex consists of a tube and an accessory piece, which features a gutter-shaped plate with a claw-like lateral process at the end.
