The right mandible shows a similarly deepened posterodorsal region starting at the posterior pole but lacking teeth; instead, parallel rows of multibranched projections transversal to the major mandible axis, gradually develop; these rows progressively reach the level of the main masticatory surface, approximately at 1/4 of the dorsal margin. Both mandibles show at the posterior pole a tooth slightly stronger than those at dorsal margin of left mandible, associated with one long and thick seta (rarely two), curved inwards (

In addition, the thoracopods 1–10 show an oval epipodite with smooth margin, and a unique preepipodite with serrated margin, with or without a small marginal notch. In the pair 11, the epipodite is big, oval and margined with around 6–11 plumose setae, and the preepipodite is a triangular much-reduced lobe, with smooth margin and apex rounded.
