Godiva quadricolor (Barnard, 1927) (Figure 35 D–E) Material examined. Six specimens. MB28-004588 & MB28-004589, ZDRS, 21 Jun. 2012, 30m, 18 and 22mm, respectively; MB28-004630, BL, 12 Oct. 2012, 3m, 32mm; MHN-YT944, ZDTR, 0.3m, 12mm; MB28-004916 & MB28-004917, NKA, 5 and 14mm, respectively. Habitats. Subtropical tidal reef, seagrass and rocky reefs and tropical coral reefs. Occurrences. Zavora, Barra and Nuarro. Geographic distribution. Indo-west, central Pacific. Introduced in the Mediterranean and Atlantic Oriental (Cervera et al. 2010). Marshall Islands, Southern Japan, Mariana Islands, Papua New Guinea (Cervera et al. 2010), South Africa (Barnard 1927), Tanzania (Gosliner et al. 2008) and Mozambique (Gosliner 1987; Fraser 2001). Remarks. In the specimens found by us the intensity of the blue on the head varied. The type locality of G. quadricolor is St James, False Bay, South Africa, although the centre of natural dispersion is uncertain (Cervera et al. 2010). This species is likely to have spread to the Mediterranean and Atlantic most likely as a result of shipping movements (Cervera et al. 2010), although this needs to be verified using molecular techniques.
