The whole body, including the gills and rhinophores is opaque (pigmented not translucent) white with a few irregular golden yellow spots scattered over the body. Six of the spots are relatively large with one of each side of the lateral processes, one in front of the gills and one behind. The smaller spots are scattered over the body but not on the head. This species differs markedly in colour and radular morphology from the two species T. brunnea and T. benni that have sympatric distributions.
