Posterior nectophore

Description
Max. size: 0.4 cm H

Polygastric phase: Anterior nectophore with five longitudinal ridges, all converging at the apex; with very shallow hydroecium and an ovoid or elliptical stalked somatocyst; mouthplate divided into two halves of almost equal size, its length about one-third as the long as nectose; anterior wall of hydroecium extending forward to the level of ostium; basal end of dorsal ridge obtuse, without toothlike projections; at the apex of the right hydroecium of the posterior nectophore a small tooth. Posterior nectophore upto 5 mm in length and 2 mm in breadth. Ridges as in anterior nectophore.

Eudoxid phase: Bract 2 mm long, conical, neck-shield short with rounded smooth margin, bracteal cavity conical; phyllocyst short, clubshaped. Special nectophore similar to posterior nectophore but smaller about 3.5 mm in length. Sexes separate in eudoxid phase; gonophores highly reduced without umbrella, sac-like.
