From: Bill Rudman & Brian Darvell

Here is some information and photos on Hypselodoris festiva from Brian Darvell's Hong Kong collections.

This second blue and yellow species of Hypselodoris is characterized by the uniform blue background colour, a median yellow line (usually unbroken), and a series of yellow spots or streaks forming a line down each side of the mantle behind the rhinophores. There is a thin irregular yellow border to the mantle and the rhinophore club and gills are edged in orange. It grows to 30 mm in length. Another species with the same species name, Mexichromis festiva (Angas, 1864) was reported earlier from Hong Kong (Orr 1981: 26 - as Chromodoris festiva).
