Hypselodoris katherinae is a species of sea slug or dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.[2]

Distribution

This nudibranch was described from Pulau Chebeh, off the NW tip of Tioman Island, eastern Malaysia, 2.932983°N 104.098690°E / 2.932983; 104.098690. It is also reported from the Philippines, Indonesia and Taiwan.[1]

Description

Hypselodoris katherinae has previously been confused with Hypselodoris carnea. The mantle is translucent pale pink with a series of longitudinal red-brown lines running down its length. These lines may be broken into short segments and may branch and anastomose. Small blue-purple diffuse spots are arranged at the mantle margin and may coalesce into a continuous line. The gills are white with orange lines on the rachis and the rhinophores are red to orange in colour.[1] This species can reach a total length of 32 mm.[1][3]
