The small size of the second maxilliped and the complex structure of its coxo-basal articulation make it difficult to determine the exact insertion point of this lobe. However, as this lobe is very near the basis and the endopod, it could also represent a rudimentary exopod. Thus, the absence or presence of an epipod on the second maxilliped, the nature of the detached rounded lobe (
