Nota: Prosome apparently 4-segmented but with the 1st free thoracic somite entirely concealed beneath a carapace-like extension of the posterior margin of the maxilliped-bearing somite. Nauplius eye absent. Rostrum fused to anterior surface of labrum, not visible from dorsal aspect. Cone organs present in lateral areas on cephalosome (see structure and function in Benthomisophria palliata). Urosome 6-segmented, somite 2 to 5 each with a hyaline frill aroud posterior border. A1 19-segmented, articulating basally with a raised area of ventral cephalic surface

Nota: Anal somite with paired lobes dorsally, either side of anus and row of minute spinules around posterior margin; pairs of pores present on both dorsal and ventral surfaces. Caudal rami about as long as wide, armed with 2 long distal margin setae, 2 medium length distal angle setae, 1 dorsal seta near the distal margin, 1 seta near the middle of the lateral margin and 1 proximal setule on this margin. P6 forming a curved plate on ventral surface of genital somite; armature incomplete.
