The facial area delimited above by the epistomal suture and below by the clypeolabral suture; giving origin to the dorsal cibarial muscles; conspicuous and projecting in adult mosquitoes. In larval insects, the dorsal apotome, if present, is commonly formed from parts of the frons and clypeus; often misidentified in mosquito larvae. In mosquito pupae, the usually poorly delimited, conspicuously bulged area between the anterior margins of the lateralia.
General: clypeus
