About Hypselodoris confetti Gosliner & R.F.Johnson, 2018
Hypselodoris confetti, a species of nudibranch, was previously confused with Hypselodoris kanga. It has a white or grey semi-translucent body covered in large yellow spots and smaller blue-black spots. The dark blue spots along the mantle edge are often stretched into patches oriented at right angles to the mantle margin, and each has a diffuse halo of bright blue around it. The gills have outer edge color lines that are purple, grading to blue, then turning red at the tips. A vertical row of round yellow spots runs along the flattened outer face of the gills. The rhinophores have bright red clubs and blue-purple bases. The closely related species Hypselodoris roo is almost identical in appearance, but differs in its gill structure: Hypselodoris roo has plain white or white spots on the outer gill faces, and the entire edge of the gills is orange-red. This species can grow to a total length of at least 35 millimeters. Hypselodoris confetti was first described from Siar Island, Madang, Papua New Guinea, at coordinates 5.183333°S 145.80667°E. It has been reported from Indonesia, Papua New Guinea, the Philippines, and Hong Kong.
