About Hypselodoris katherinae Gosliner & R.F.Johnson, 2018
Hypselodoris katherinae is a species of nudibranch that was previously confused with the related species Hypselodoris carnea. Its mantle is translucent pale pink, marked with a series of longitudinal red-brown lines that run down the length of the mantle. These lines can break into short segments, and may also branch and anastomose. Small diffuse blue-purple spots are arranged along the mantle margin, and these spots may coalesce to form a continuous line. The gills of this nudibranch are white, with orange lines along the rachis, and its rhinophores range in colour from red to orange. This species can grow to a total length of 32 millimetres. Hypselodoris katherinae was first described from a specimen collected at Pulau Chebeh, off the northwestern tip of Tioman Island in eastern Malaysia, at the coordinates 2.932983°N 104.098690°E. It has additionally been reported from the Philippines, Indonesia, and Taiwan.
