Representatives of this genus are characterized by extremely long, thread-like bodies of firm consistency. They resemble Emplectonema in form, habits, and general internal anatomy, but differ in haying only four ocelli, which are symmetrically placed on the head, in armature of proboscis, and in other anatomical details.
The worms are quite as slender as those of the genus Cephalothrix, but they do not coil the body in a spiral.
Proboscis sheath very short, proboscis armed with well developed central stylet and basis, and with two pouches of accessory stylets; cerebral sense organs small, situated well in front of brain. Cephalic glands usually well developed.
