Description
Polygastric Phase: Anterior nectophore: Ridges heavily and irregularly serrated. Apico-dorsal facet sharply bent upward from insertion of lateral ridges to transverse apical ridge. Lateral expansion sharp, prominent. Facets depressed below ridges.

Posterior nectophore: Characterized by smaller number of comb-teeth (6-8); presence of two rows of teeth on basal margin of right ventral wing; heavier serrations of ostial teeth.

Eudoxid phase: General features: Bract is an 'amphiroa' with rectangular apical, ventral and dorsal facets. Two large lateral facets. Phyllocyst with 3 branches but distal end of median thick branch not curved upward, anterior arms thin and directed toward apical corners.
