Kyopoda
This genus is known only from six specimens collected by SCUBA divers in northern British Columbia and southern California in 1976 and 1985; it occurred in areas of wave surge and was color-matched to its substrate and very difficult to see (Larson, 1988; Ronald Shimek, personal communication).
Since only a single species of Kyopoda is known (Kyopoda lamberti), the diagnostic description for the genus is the same as for the type species: Stauromedusae with four simple perradial gastric cavities and without a claustrum or mesogonial pocket; the basal portion of the stalk is enlarged and contains the stomach and gonads, which are absent from the calyx (Larson, 1988).
Known from British Columbia and California on the Pacific coast of Canada and the United States, and likely occuring along the entire coastline between the Queen Charlotte Islands (Haida Gwaii) and southern California (Larson, 1988).
