Genus diagnosis. Corynidae have a bell-shaped umbrella with four radial canals, and a ring canal. Tentacle bulbs swollen, each with an abaxial ocellus. Manubrium short, not extending beyond umbrella margin and without thin proximal part. Gonads undivided, and encircle manubrium for nearly its entire length, leaving manubrium visible only at the top and near the mouth. Four tentacles arising from bulbs with a single egg-shaped nematocyst swelling at tips.

Type species. Caltsacoryne setouchiensis

Etymology. The genus name Caltsacoryne is taken from the Greek words “kaltsa” and “koryne,” meaning “sock” and “club,” respectively. The gender is feminine. The name reflects the illusion that the medusa appears to be wearing socks on the tentacle tips.
