mandibulata

from The Century Dictionary.

• In entomology
• In some systems, a primary group or division of Insecta, containing those insects whose mouth-parts are mandibulate or masticatory, as distinguished from those which have the same parts haustellate or suctorial, the former being fitted for biting, the latter for sucking: opposed to Haustellata. Westwood called the same division Dacnostomata.
• A division of Anoplura, including mandibulate lice, as the bird-lice or Mallophaga.
