de Haan, 1833
Regions of the carapace separated by deep and narrow furrows, sometimes not easily distinguished one from the other. Regions invested either with petaliform groups of tubercles, coalescing into a mosaic, or with separated, diversely shaped tubercles: squamiform, spiniform, petaliform or noduliform. Ambulatory legs with an ornamentation similar to that of the carapace regions. (Guinot 1998)
