A. Milne Edwards, 1873
The carapace in this genus is almost entirely hairless, the fronto-orbital distance is wide and nearly equals the greatest width of the carapace, the pyriform eyestalks present minute, though quite distinct, eyes, and the ambulatory legs are elongate, and, like the carapace, almost devoid of hairs. (Tesch, 1918: 219)
