Definition:

In many immature insects, the cranial area bounded laterally by the frontal ecdysial lines and apically by an imaginary line between the most apical parts of the frontal ecdysial lines; there is no necessary homology between the cranial area included in the dorsal apotome of different insects. In mosquito larvae, perhaps homologous with the dorsal apotome of mosquito pupae.
