Swimming keel of club slightly shorter than carpus; dorsal and ventral protective membranes not joined at base of club; extend proximal to carpus along stalk as low ridges. Cuttlebone outline oval, broad; cuttlebone width 33 to 43% cuttlebone length; strongly convex in lateral view; granulose dorsally; dorsal median rib distinct. Spine absent. Striated zone and last loculus convex; sulcus extends entire length of cuttlebone. Inner cone limbs are uniform width, narrow, inner cone U-shape posteriorly, thickened, raised in the centre as a rounded knob; outer cone chitinous, spatulate, expanded. The tentacles are very long and slender. The swimming membrane of the tentacular clubs is slightly shorter than the club.
