discussion
Remarks. Paralibrotus has a number of highly derived characters which make it difficult to characterize. Based on the gnathopod 1 large coxa and short carpus, and an entire telson it is most similar to Onisimus. It differs mainly in the reduced flap-like molar and the simple first gnathopod.
