Epistome weakly but distinctly protruding in front of upper lip (or level with upper lip). Maxilla 1 palp distal end strongly convex, with conical distal spines not contiguous. Maxilliped inner plate, distal margin regularly beveled, very slightly concave, with mediodistal extension slightly surpassing the level of the outer corner; outer plate inner margin weakly scalloped.

Gnathopod 2 propodus of female slender, length ~3 × width (similar in form to male), dactylus small, inserted in the middle of the distal margin, lacking a palm concavity.

). As previously noted (p. 34), eye shape and size are best recognized in freshly collected specimens. Over long periods of time in alcohol preservation, colour pigments fade and are lost, causing the eyes to become extremely difficult to ascertain. This problem may be a contributing factor in the discrepancies seen in eye morphology described by the authors above.
