Diagnosis

Carapace xanthoid in shape, not particularly broadened; dorsal surface granular, tuberculate or spinose, regions usually well defined and lobulate. Anterolateral margins with three teeth, or granular or spinose lobes, behind exorbital angles. Front bilobed, weakly to moderately projecting; width about one-third maximum carapace width; lateral margin with ventral prolongation meeting basal antennal article such that antennal flagellum included within orbit. Antennules fold transversely. Chelipeds subequal, slightly dissimilar in males; granular or spinose; fingers variable, from obtusely pointed to acute but never enlarged and hollowed. Walking legs granular, spinose, sometimes smooth, or even carinate; sometimes coadapted into concave posterolateral carapace margins. Sternum relatively narrow; fourth sternite with longitudinal furrow more or less marked.
