The cibarium is the anterior/dorsal part of the preoral cavity. Its proximal boundary is marked by the frontal ganglion (Snodgrass, 1935), where the morphological mouth is situated. The cibarium is continued into the anterior part of the alimentary canal, the pharynx. The anterior wall of the cibarium is the proximal part of the epipharyngeal wall, the posterior wall is the hypopharynx.
