(Based on female RBINS, INV. 132538; with reference to complementary illustrations of the holotype, MNHN AM 831).

Body dorsal armature (Figs 6, 7A): Pereionites 5–7 and pleonites 1–3 with mid-dorsal carina backwardly prolonged into strong tooth; dorsal profile of pleonite 3 distinctly sigmoid.

Epimeron 1 (Figs 5D, 14A): Narrow, tapering distally and posterodistally pointed, posteroventral margin nearly straight.
