Anterior tentorial pit
Description:
One of the pair of pits located at or close to the posterior clypeal margin. The pits indicate the points of attachment of the anterior arms of the internal skeleton (tentorium) of the head to the head capsule. The tentorium is an H-shaped structure, which provide both strength to the head and some sites to the attachment of muscles that insert on mouthparts. The termination of the posterior arms of the tentorium are marked by a pair of posterior tentorial pits, located close to the occipital foramen.
