A) Anterior nectophore; B) Posterior nectophore; C) Eudoxid stage

Description
The polygastric stage anterior nectophore is rigid and not spiralled, up to 7.4 mm high by 2.5 mm wide. There are 5 ridges on the nectophore which all reach the apex, serrated on the lower nectophore. Hydroecium has a rounded apex. The basal lamella is divided into 2 serrated wings, the left wing with a central tooth-like projection. The somatocyst is sausage shaped, starting off very narrow and reaches halfway up the nectosac.
Posterior nectophore 2/3rd length of anterior nectophore; ridges and dorsal tooth present. Apical-dorsal notch present between apex and pedicel. Hydroecial groove open except near upper end; broad right hydroecial flap overlapping longer tongue shaped extension of left wing, forming a closed canal; right and left hydroecial wings end in pointed serrated teeth below ostium, left tooth longer; deeply curved tooth occur on each hydroecial wing at level of ostium.

Eudoxid phase about 8 mm in length, bract and gonophores nearly equal in length. Bract with pointed apex, sutural surface forming acute angle with dorsal wall of deep, conical bracteal cavity. Ridges and edges of neck-shield serrated; with small pointed teeth at distal edge. Phyllocyst pear-shaped. Pedicel of gonophores long, with four prominent flared serrated ridges ending in two teeth. Mouth plate with concave edge and two lateral teeth. No special nectophore; manubrium shrinks completely after shedding sperms or eggs.
