Nausithoe rubra Vanh ̂ffen, 1902: 30–31, pl. I.

Holotype ZMB 14808.

Material examined: NMNH 28128 View Materials and 28129 (two specimens from Peru, no information on depth), NMNH 55931 View Materials (one specimen from California, USA 1975, depth: 900m) , AMNH 2113 About AMNH (one specimen from Tower Island, Galapagos 1925, depth: 372m) and MBARI database (identity-reference 46, coast of California 2013, 36°39’N 122°67’W, depth: 1,210m) .

Diagnosis: medusa—hyperdome red-purple bell with blue stomach.

Description: Based on original description, Bigelow (1928), Mayer (1910), and Kramp (1961). Adult medusa up to 15 mm in diameter; exumbrella surface of central disc covered with nematocysts; pointed marginal lappets; tentacles and bell red-purple, stomach blue; gastric septae broadly triangular; narrow perradial gastric ostia. No information about a polyp stage.

Type locality: East Atlantic (9°31’N 9°46’E, Benguela current, 2,000m depth) GoogleMaps .

Distribution: possibly a worldwide species in deeper waters.

Remarks: Examined specimens with brownish smooth umbrella, with narrow pointed lappets (in some specimens the marginal lappets were very damaged, making it difficult to verify their morphology). Eight rhopalia with statocyst and a darker brown bulb at the base. Triangular faint orange or dark purple gonads, pointing to the margin and containing hundreds of eggs. More than 50 gastric filaments in total, close to 12 per quadrant. Some specimens had dense, white “warts” (nematocysts?) on the exumbrellar surface. The largest animal was 20 mm in diameter and had tentacles as long as 15 mm.
