Hypselodoris apolegma is a species of colourful sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.

Taxonomic history[edit]

Recent phylogenetic data confirm the validity of the species and suggest a sister species relationship between Hypselodoris apolegma and Hypselodoris bullockii.^[2] A later study revealed a large clade of animals with similar colouration with Hypselodoris brycei as sister species to H. apolegma.^[3]

Distribution[edit]

This nudibranch is found in the tropical Western Pacific Ocean.^[4]
