Anterior nectophore

Description
The anterior nectophore of the polygastric phase has 5 complete ridges and is up to 7.2 mm in height and 2.3 mm in width. The hydroecium is very shallow and does not reach the bottom of the nectosac. The basal lamella is quite flat, divided into 2 downwardly slanting wings. The somatocyst varies in shape, but tends to be short and broad with a short stalk and sloping outwards.

Posterior nectophore: Nearly equal to anterior nectophore in length. Mouth plate with rounded notch in distal margin. Upper articulating end of left ventral hydroecial wing not square but angular.

Eudoxid phase: Bract 1.2 mm long; phyllocyst long and slender, neck shield smooth. Gonophores-like posterior nectophore but small, with a notch in mouth plate.
