Identification
mandible noun, plural mandibles or mandibulae, adjective mandibular - the biting jaws of an insect or other arthropod, which are two strong corneous (made of horny material) bent hooks, their inner margin being more or less dentate (toothed); and which articulate with the genae at their broad bases. The mandibles move in a hinge-like fashion (ginglymus) opposed to each other like the blades of scissors. Diagrams and labeled photos of the mandible:

Remarks
Like many features of insect anatomy, mandible was originally a term for an analogous (but not homologous) vertebrate structure.
