Material examined: ZMA2048 ( 8 specimens from Indonesia , Maluku , no information on depth) and photo from underwater photographer, Fabien Michenet ( Tahiti , depth: 20m ) . Diagnosis: medusa—hypodome with transparent umbrella and blue gastric filaments. Description: Based on original description and Mayer (1910) . Medusae 15–22 mm in diameter; smooth transparent umbrella; marginal lappets as long as wide, with rounded edges; tentacles length equal to bell radius; 4 groups of about 12 blue gastric filaments each; large brown gonads; rhopalia with brown ocellus. Type locality: Rangiora Island, French Polynesia (near surface). Distribution: French Polynesia and Central E Pacific Ocean. Remarks: The morphology of this species resembles that of N. clausi and N. punctata , except for the blue gastric filaments, rendering this as the only feature that distinguishes the medusa of N. picta .
