Dermatobranchus caeruleomaculatus can be distinguished from other arminaceans by the whitish mantle with rows of small brown spots on it. The margins of the mantle, foot and oral veil are orange with bright blue spots - with a small dark blue/black spot in it.
This species is as Dermatobranchus sp. 12 in IPN at page 312, it was posted on 28 April 2004 at these websites as Armina sp. C,
and on 1 December 2010 changed into Dermatobranchus sp. H, on 29 July 2011 changed changed into Dermatobranchus sp. 08,
and on 25 August 2011 changed changed into Dermatobranchus caeruleomaculatus Gosliner & Fahey, 2011.
In this almost white specimen are the distinctive blue spots at the mantle margin very hard to see, that is why I posted it on 29 April 2004 as seperate species, Dermatobranchus sp. F.
I have posted more pictures of Dermatobranchus caeruleomaculatus than usual to show the variations in the appearance, from white to brownish-tan.
