Body elongate but more compact than in most other species, about 2.5 times as long as maximum width, dorsoventrally flattened. Cephalon completely fused to first pereonite, forming the cephalothorax; original segmentation marked by dorsal groove and weak lobate extensions at posterolateral corners; distinctly wider than long, clearly narrower than pereon; anterior margin rounded. Antennule bilobate, outer lobe with non-articulated flagellum. Antenna 2-segmented; with broad basal part and elongate, posteriorly directed, slender part; not extending to posterior margin of first pereonite. Pereonites 2–6 completely separated, pereonite 7 almost completely fused dorsally with pleon; lateral margins of pereonites 2–6 rounded, those of seventh conical or rounded. Pleon conical, markedly narrower than pereonite 7, representing 31–40% of body length; posterior margin rounded.

) description of the cephalic appendages is grossly inadequate and difficult to interpret. The author states that the antennules and antennae are absent in the female and ‘… some mouth parts [are] distinct, but most not immediately apparent as mouth parts’. It is indeed unclear which appendages Schultz’s figures (his fig. 18C-G) refer to. His description of the male antennule and antennae is similarly ambiguous, the former being described as consisting of three conical segments with a single aesthetasc on the distal one, and the latter as 4-segmented, composed of a broad irregularly-shaped peduncular segment, supporting two subequal, narrow segments, and a small apical segment tipped with several setae.
