Description This goniodorid nudibranch is translucent white in colour, with yellow-orange markings. The rhinophores, gills and processes are tipped with yellow pigment which becomes orange at the extremities. It is very similar in colour to Trapania hispalensis except that in that species the yellow markings are uniform in colour.Rudman, W.B., 2001 (February 10) Trapania tartanella (Ihering, 1886).
