Holotype description: Medusa 20 mm in bell diameter and 14 mm in bell height, with a deep coronal groove. Central disc with thick jelly, subspherical, flattened in the oral-aboral plane. Exumbrella (both central disc and pedaliar region) densely sprinkled with numerous nematocyst warts, each about 0.1 mm diameter. Rhopalia six, in deep niches between lappets; lappets 12, rounded, broader than long. Tentacles six, each longer than the bell diameter in life, but shorter than bell diameter in fixed material, each with an opaque capitate tip densely covered with nematocysts. Coronal muscles weakly developed. Mouth short, circular, not obviously cruciform. Stomach with four groups of gastric cirri, each group arising from a gelatinous stalk bearing 20-30 filaments. Gonads eight, fusiform (0.5 mm x 2.0 mm), conduplicate axially, arranged in four near-interradial pairs, each pair abaxial to a group of gastric cirri. Gonads cream-tan, medusa otherwise colorless and transparent, and bearing no zooxanthellae.
