Mexichromis porterae is one of a number of blue chromodorids with yellow markings from the eastern Pacific. It is characterised by the thin white border to the mantle, a bluish white line down the dorsal midline and bright yellow line down each side of the mantle. The species it resembles most closely in colour is Chromodoris macfarlandi which has a violet background colour, a white border, and three yellow longitudinal lines. Another species, Hypselodoris californiensis, is dark blue with yellow spots. Grows to 35 mm in length (Behrens, 1991 )
