Goniobranchus reticulatus is one species of a complex of species with a reticulated network of red lines on the mantle, IPN lists:
Chromodoris cf. alderi, Chromodoris sp. 2, Chromodoris sp. 3, Chromodoris sp. 4, Chromodoris sp. 5, Chromodoris tinctoria,
Chromodoris reticulata, Chromodoris sp. 6, Chromodoris sp. 7, Chromodoris sp. 8, and Chromodoris sp. 9.
There are no submarginal spots in Goniobranchus reticulatus and there is most commonly no marginal band, some specimens have a faint orange marginal band. It has distinct tubercles over the surface of the body. The gill rachis on the inner side of the gills is opaque white.
Pretty similar are:
Goniobranchus sp. 03 which differs by its more diffuse reticulated pattern and by its orange marginal band,
Goniobranchus sp. 04 which differs by purple tipped white tubercles, and by its orange marginal band.
Bill Rudman's Sea-Slug Forum has all species of this complex as Chromodoris tinctoria.
This species was posted on 21 May 2003 at these websites as Chromodoris tinctoria (Rüppell & Leuckart, 1828) [Doris],
I decided on 12 April 2011 to follow IPN and keep it distinct, I changed it into Chromodoris reticulata (Pease, 1866) [Goniobranchus],
R.F. Johnson & Gosliner (2012) moved it to the reerected ("rescued from synonymy") genus Goniobranchus  Pease, 1866.
