Description
The anterior nectophore of the polygastric stage is very rigid, up to 20 mm in height. There are 5 ridges but only 3 reach the apex. The hydroecium is quite deep, directed outwards. The basal lamella is divided into 2 square wings. The somatocyst is long and spindle shaped, varying between narrow and thin, reaching two-thirds to three-quarters the length of the nectosac.

Posterior nectophore: About 7.7 mm long, 2.7 mm wide, slender, ridges present. No ostial teeth. Ventral ridges extended to form hydroecial wings and end in two serrated teeth of which left one is larger; triangular flap from left hydroecial wing cover hydroecium completely.

Eudoxid phase: Bract up to 3.1 mm in length, conical apex pointed with conical braceal cavity. Phyllocyst long, cylindrical with tapering apex reaching upto apex. Neck-shield short, margin smooth without any teeth or serration. No special nectophore. Gonophores 3.5 mm long, with 4 ridges, slightly curved, ending in teeth near ostium, male and female gonophores occur in different eudoxids.
