Stimpson, 1858

The whole surface of the body and feet is hirsute with the exception of the tips of the fingers. The pubescence is rather less dense below than on the upper surface, where there are numerous setae of greater length interspersed. Carapace convex; proportion of length to breadth, 1:1.33. Anterior margin nearly semicircular in outline and forming more than half the circumference of a circle. Postero-lateral margin strongly concave and about equaling the posterior margin in extent. The areolets of the surface may be easily traced, but not strongly marked, the shallow sulci of separation being filled up with pubescence. The surface of the areolets is covered with sharp granules. Antero-lateral margin four-lobed, angle of orbit not included; the lobes distinct; first lobe small; third and fourth lobes depressed, subtriangular. Lobes of the front prominent, deflexed, with smooth edges. Subhepatic region minutely granulous, but not sulcated. Feet all strongly granulous and hairy on their exposed surfaces. In the cheliped the fingers are hairy at their bases, longitudinally grooved, and 5-toothed on the inner edge. In the ambulatory feet the antepenult joint is grooved above. The species has much resemblance to Actaea hirsutissima, but the carapax is not so deeply areolated, and the subhepatic region is not grooved with sulci proceeding from the notches of the antero-lateral margin.
