Cephalis large, divided into three lobes by two lateral furrows directed obliquely and downward from the apical spine to the base of the cephalis. The upper unpaired lobe is located above the two smaller paired ones (trilocular cephalis); these basal paired lobes are not always conspicuous. Many pterocorythids are two or three-segmented, lacking postabdominal segments.
