Off-white body with 2 or 3 irregular rows of orange spots along the edge of the notum. Spots increasing in size and irregularity from outer to inner row. An additional row of orange circles/ovals is present just anterior to the rhinophores along the body just lateral to the mid dorsal region, each orange marking being banded by a conspicuous white line. Mantle covered in low, closely spaced tubercles. Distal portion of the rhinophores a light brown with a prominent medium white longitudinal septum on both anterior and posterior faces. See my discussion below about whether this could be a species of Tyrinna.

[Nomenclatural Note: The publication cited below in which this species is described has multiple authors but the description of this species is entitled 'Chromodoris marislae, Bertsch, spec. nov.' indicating that Bertsch is the sole author of the name. A full citing of the name would be 'Chromodoris marislae Bertsch in Bertsch, Ferreira, Farmer & Hayes, 1973.]
