From their attachment adjacent to the hypostome they stretch inward and forward, almost touching each other at the point where, from a dorsal viewpoint, they appear from under the cephalic margin, then bending outward and then forward again in a slight S-curve.
These appendages extend from their attachment near the hypostome, curve inward and forward, nearly touching each other at the point where, viewed dorsally, they seem to emerge from beneath the cephalic margin, before bending outward and then continuing their forward path in a gentle bend.
