Clypeus

For the ancient Greco-Roman shield, see Clipeus

The clypeus is one of the sclerites that makes up the "face" of an arthropod.

In insects, the clypeus delimits the lower margin of the face, with the labrum articulated along the ventral margin of the clypeus. The mandibles bracket the labrum, but do not touch the clypeus. The dorsal margin of the clypeus is below the antennal sockets. The clypeus is often well-defined by sulci ("grooves") along its lateral and dorsal margins, and is most commonly rectangular or trapezoidal in overall shape.

In spiders, the clypeus is generally defined as the area between the anterior edge of the carapace and the anterior eyes.^[1]
