Habitats. Subtropical tidal reefs, rocky reefs and tropical coral reefs and bommies. Occurrences. Ponta do Ouro, Zavora, Nuarro and Vamizi Island. Geographic distribution. Indo-west, central Pacific. Hawaii, Midway Atoll (Gosliner et al . 2008), Japan ( Baba 1949 ), Papua New Guinea , Seychelles , Réunion Island (Gosliner et al . 2008) and Mozambique ( Martens 1879 ). Remarks. Three-colour morphotypes were found: yellowish with a delicate reticulated pattern on the dorsum ( Fig. 2 B ); a translucent yellow body with low yellow tubercles ( Fig. 2 C ); and an orange body with white specks ( Fig. 2 D ). The variety of habitats, depths and specimen colours suggest that the animals collected here probably represent a complex of species. The systematics of Berthellina from the Indo-Pacific are in need of a comprehensive review ( Cervera et al. 1999 ; Moustafa et al. 2016 ), because this taxon is indistinguishable by external characteristics alone ( Gardiner 1936 ; Gosliner et al. 2008; Alvim & Pimenta 2015 ).
