Treatment

Thecacera pacifica ( Bergh, 1884) View in CoL

( Figure 23 I –J View FIGURE 23 )

Material examined. Three specimens. MHN-YT1349, NKA, 13 Jun. 2014, 19m, 15mm; MB28-004 909, NKA, 13 Jun. 2014, 18m, 9mm; MB28-0 0 4962, ZSC, 28 Jan. 2015, 21m, 18mm.

Habitats. Subtropical rocky reefs and tropical coral reefs.

Occurrences. Zavora, Nacala and Nuarro.

Geographic distribution. Indo-west, central Pacific. Hawaii, Japan, Vanuatu, Philippines, Indonesia (Gosliner et al. 2008), Australia (Nimbs et al. 2016), Red Sea (Gosliner et al. 2008), South Africa ( Gosliner 1987) and Mozambique ( Macnae & Kalk 1958 as T. inhacae ).

Remarks. The two specimens found in northern Mozambique exhibit additional bluish-black stripes posterior to the gill and on the lateral dorsum ( Fig. 22 D View FIGURE 22 ). The other specimen from the south lacks these stripes, and matches Bergh’s description (1883). Additional stripes appear to be merely a colour variation, but further studies are needed to confirm this hypothesis.
