Pair of short, thick main branches directed laterally from base of middle piece, subequal in length to pair (anterior and posterior) of rather short, thick, widely outspread primary branches on each side. Each anterior primary branch giving rise to 2 (left) or 4 (right) secondary branches, arising alternately right sides and dichotomously on terminal of anterior primary branches. Short tertiary branches with lobe-like quaternary branches arising alternately on the second branches. Posterior primary branches extending laterally or posteriorly, 3 short secondary branches similar manner as anterior secondary branches arising alternately on each of the posterior primary branches. Ends of all branches bluntly rounded, without terminal protuberances.

can be clearly distinguished from the other species of this genus by the unique ramification pattern of the female mantle. This features 1) short and stout main branches, 2) thick roots of the two pairs of primary branches, and 3) alternate positioning of all secondary and tertiary branches. Furthermore, the proximal basal lobes on the posterior processes of male carapace are characteristic for this new species.
