Tritoniopsis elegans Audouin, 1826 View in CoL

( Figure 29 I –J View FIGURE 29 )

Material examined. Seven specimens. MB28-004506, ZRP, 21 Feb. 2012, 2m, 27mm; MB28-00 4677, ZRP, 25 May 2013, 0.5m, 44mm; MB28-004691, ZRP, 12 Jul. 2013, 0.5m, 45mm; MHN-YT904, ZRP, 0 8 Sep. 2013, 0.5m, 45mm; MB28-004965, ZRP, 0 6 Feb. 2015, 0.5m, 50mm; MB28-005017, ZRP, 0 4 Aug. 2015, 1m, 42mm; MB28- 0 0 4510, ZRP, 21 Feb. 2012, 1m, 33mm.

Habitats. Subtropical tidal reef.

Occurrencces. Zavora.

Geographic distribution. Indo-west Pacific. Japan, Papua New Guinea, Philippines (Gosliner et al. 2008), Indonesia ( Yonow 2011), Thailand (Gosliner et al. 2008), Australia, Red Sea ( Audouin 1826), Kenya, South Africa (Gosliner et al. 2008) and Mozambique.

Remarks. This species appears to be variable in colour (29 I –J). Two morphotypes were found: morphotype 1 which is completely white with longitudinal opaque white lines ( Fig. 29 I View FIGURE 29 ) and morphotype 2 which has a reticulate pattern of white and orange on the dorsum ( Fig. 29 J View FIGURE 29 ). Additional studies are needed to verify if they are the same species.
