Another unique character present in the new genus is the peculiar cuticular processes of the cephalothorax, forming sac-like protuberances on the anteroventral surface but also dorsal folds. An important apomorphy found in this genus is the absence of an inner seta on the first segment of the exopods of legs 14. The absence of such a seta is shared only with

). The presence of a ventral process on the first post-genital somite is also a unique character; the ventral surface of all postgenital somites is always smooth. This kind of structure has not been described in any other monstrilloid; its function and/ or homology are intriguing. The urosome segmentation is similar to that found among males of
