Shield and cephalic appendages. - Ocular scale with a single terminal spine. Species of normal size, i.e. shield length often greater than 2–3 mm. Anterodorsal plate of branchiostegite unarmed on dorsal margin or with 1–2 spinules subproximally.

Chelipeds (P1). - Upper margin of right chela tuberculated or spinous. Outer face of left palm regularly convex.

Ambulatory legs (P2-P3). - Dorsolateral margins of P3 propodi rounded. Dactyl of P3 subequal to propodus or slightly shorter. Distal pilosity of P3 weak, similar to distal P2. Ventral margin of P3 dactyl with less than 10 spines.

Armament of telson. - Left lobe of telson with several spines disposed on posterior margin only. Right lobe with several spines.

Coloration. - Shield purple-brown (General color of bod purple with red spots). Ocular peduncle multicolored with narrow ring close to cornea (eyestalks purple near base but with increasing red distally; area proximal to cornea white). Chela with brown, dark orange or red patches (cheliped purple; an irregular row of red pigment along upper margin of hand extends to dactyl). Ambulatory legs (P2 & P3) with ring(s) (rows of red pigment on faces of segments).

Habitat. - Shallow-waters (subtidal to 110 m).

Geographic distribution. - Endemic to Bermudas. West Atlantic.
