Introduction
The Tripedaliidae has not been widely adopted, but rather, has generally been considered to be within the Carybdeidae (in the historical sense). However, Gershwin (2005: 103) regarded the family as valid, comprising the genus Tripedalia and a yet unnamed new genus for the curious "Carybdea sivickisi". In this sense, the family is distinctive in having gonads that arise from the mid-point of the interradial septa, and take on a butterfly-like appearance as they grow. Both genera further have complex mating behaviours (Hartwick, 1991; Lewis & Long, 2005).
Diagnosis
Carybdeida with gonads attached along middle half of interradial septum, having a butterfly-form appearance; with rhopalial niche ostium of a shallow frown shape, with a greatly reduced lower covering scale; with single-stalked gastric phacellae; with 1 or more separate unbranched pedalia per corner.
