Organism information awaits expert curation
Class: Hydrozoa

Pneumatophore: Small 6 mm X 1 mm with two chambels.

Nectophore: 4 to 11 mm long; 2.2 to 5.53 mm broad; twice as long as broad. Younger nectophore almost cylindrical from apex of nectosac to ostium; older ones bulged in mid-region. Proximal 1/4th part flat, triangular with pedicular canal lying in centre, extending to proximal tip. Muscular lamella extend along entire length of triangular extension on ventral side. Dorso-lateral ridges prominent, extending from lateral upper edge, curving towards centre and diverging again terminating near lateral corners of ostium. Dorso and ventro-lateral ridges connected by a single very much oblique lateral ridge, extending from proximal end of nectosac to ostium. Nectosac cylindrical with a slight notch or embayment at proximal end, without musculature in this region; filled with mesoglea. Dorsal and ventral radial canals simple and straight; lateral radial canal with slight sigmoid curve at latelal sides of nectosac. Ostium dorsal, with clefted mouth-plates.

Siphosome: Orange colored, 3.0 mm thick, with remains of continuous series of muscular lamellae of bracts.

Gastrozooids: 30 mm X 7 mm with series of large irregular ridges and villi of mesoglea projecting into lumen.
