Lorica firm, lightly stippled, greatly compressed dorso-ventrally and composed of dorsal and ventral plates. Antero-dorsal margin with six spines, intermediate spines considerably larger than laterals and medians, curve laterally outwards or ventrally towards head of the animal. Median spines mostly equal to laterals but sometimes smaller. Mental edge firm and wavy without spine and without elevation towards the center. Posterior spines widely separated basally, long, their width much more than anterior spines, parallel or bow outwards, converge, then twist towards their apices, thus completing full arch.
