Description
Nectophore: Larval nectophore caducous. Definitive nectophores occur in a series of one to several pairs, all similar in shape and structure. Nectophores short, pentagonal, prismatic, 11.7 mm-15 mm long, 16.5 mm-20 mm wide, with pointed tip at anterior end; dorsal facet produced into flared out pointed tips at lateral ends; dorsal, lateral facets and ridges bear varying number of tubercle-like characteristic spines; ventral facet smooth; devoid of spines. Base of nectophore below nectosac produced into two clefts.

Somatocyst simple, thin, thread-like and unbranched. Nectosac large, round with large round ostium; lateral radial canal arise at different points from dorsal radial canal. Rete mirabele on ventral radial canal, covering entire upper surface of nectosac in young nectophore; as two lateral wings in older nectophores.

Gastrozooids with short stalks, pink in color, tentacles bearing bright yellow to brick red tentilla in life. Both male and female gonophores present in each cormidium.
