There are many similar coloured chromodorids which Bill Rudman calls the "Noumea purpurea colour group".
Pretty similar are:
Verconia norba, which has also a white band around the gill pocket but a pale pink mantle,
Verconia varians, which has no white patch or band around the gill pocket, and differs by the pink or orange background colour,
Verconia alboannulata which has an opaque white band in the midline which splits just behind the rhinophores to form an elongate oval which encircles the gill pocket and
Mexichromis pusilla which has an pale pink mantle with an elongate white streak in the midline between the rhinophores and another in front of the gills, but not around the gill pocket.
This species was posted on 30 January 2005 at these websites as Durvilledoris similaris Rudman, 1986,
R.F. Johnson & Gosliner (2012) moved Durvilledoris similaris to the genus Mexichromis Bertsch, 1977.
