Mexichromis trilineata (A. Adams & Reeve, 1850) [Goniodoris]

Click the thumbnail photos to enhance!

Mexichromis trilineata is characterized by three longitudinal lines, as the name suggests. The body colour varies from pale blueish to purple, there is a thin white marginal line, which is in some specimens orange. The three longitudinal lines are usually yellowish-orange with a white edge on each side. Sometimes the lines can be broken into a series of dashes, or the outer two lines can be absent. The rhinophores are orange, in some specimens basally translucent with a broad white median band. The gills are translucent with an orange edging, in some specimens basally white.
I have posted more pictures than usual to show some of the variants.
There are many similar coloured chromodorids which Bill Rudman calls the "Noumea purpurea colour group".
It was originally posted at these websites as Pectenodoris trilineata (Adams & Reeve, 1850) [Goniodoris]
I follow the recent article (published: 10 April 2012)

and move Pectenodoris trilineata to the genus Mexichromis  Bertsch, 1977.
