Unique among zoantharians, species in this genus have an endodermal sphincter with brachycnemic mesentery arrangement. Polyps are only partially incrusted, with the oral end of polyps lacking incrustation (Figures 4C, D). Phylogenetically, this genus is closely related to Isaurus   (within family Zoanthidae   ). Zooxanthellate. Adapted from Herberts (1972), Reimer et al. (2012a).


Regions recorded in this study (Figure 5). Eastern Bali (5), Spermonde Archipelago (9), Tukang Besi Islands (12), Moluccas (14).

Previous records. Species of this genus have been reported from Madagascar ( Herberts 1972), southern Japan ( Reimer et al. 2011a, 2012a, 2013b), and the southern Great Barrier Reef ( Reimer et al. 2011a, 2012a).


This genus was originally described from Madagascar with the type species Neozoanthus tulearensis   Herberts, 1972. Subsequently, two species have been reported from Australia and Japan ( Reimer et al. 2012a). As no specimens exist, it is impossible to determine if the Indonesian photographs constitute one or both of the species reported in Reimer et al. (2012a), or an as of yet undescribed species.
