No. That one is not named as a own species e.g. by the aqualog. I don't think this is a separate species, either. They name it Carinotetraodon cf. travancoricus. At breeding time darker dwarf puffers among others can get more colourful and when looked at with the right (bright) light some have this bluish colour within their dark spots.
The C. imitator is shown on pages 17, 44, 45 (at least in my edition)
