A) Complete polygastric stage; B) Eudoxid stage

Description
Polygastric phase: Anterior nectophore: Size: length-3.78 mm; breadth 3.78 mm; Somatocyst-1.75 mm; hydroecium 2 mm; nectosac 2 mm. The polygastric stage is rigid with pronounced serrated edges. Nectophore ridges sharp and serrated. The wide somatocyst has a short projection at the top. Apex of nectosac not extending above main body of somatocyst. Dorsal facet pefectly pentagonal. Lateral radial canal not arched (upward loop).

Posterior nectophore: Length 7 mm, breadth -3.5 mm, twice as long as broad. With 5 prominent, complete, highly serrated ridges; both hydroecial wings (ventral ridges) with secondary flaps overlapping and fusing to form a closed hydroecial tube in proximal half; flap on inner surface of left ventral wing with 5 denticulations along basal margin; right ventral wing 3-4 teeth. Nectosac with 4 simple, straight radial canals.

Eudoxid phase: Bract: 2.48 mm long, 2.96 mm broad, perfectly pentagonal in shape. Basal cross ridge of lateral facet higher up. Lateral ridges of dorsal facet sloping towards apical facet instead of being vertical. Phyllocyst present.

Gonophore: Small, 2.3 mm to 3.5 mm in length. With four serrated ridges, ventral one curving over to lateral side and joining dorsal and apico-lateral ridges. Sexes separate.
