This biting and chewing type of mouthparts are considered as the most primitive and unspecialized of all the mouthpart types. It is the upper-most of the mouthparts and located on the midline. The galeae fit tightly lengthwise, against the elongated labial palps and they in turn roof over the elongated glossae (tongue) to form a temporary food channel through which saliva is discharged.
