Heteronemerteans have no stylet attached to the proboscis. The mouth and the proboscis pore are separate, with the mouth placed ventrally and the proboscis opening in the anterior tip of the head. Most heteronemerteans bear cephalic slits, a character that is obvious and easy to distinguish. A few heteronemertean species lack those slits.
