Tibiriçá & M. Malaquias.

Habitats. Subtropical rocky reefs, wrecks and tropical coral reefs.

Occurrences. Ponta do Ouro, Zavora and Vamizi Island.

Geographic distribution. Indo-west, central Pacific. Hawaii, Guam (Gosliner et al. 2008), Japan ( Baba 1949), Palau, Papua New Guinea, Australia, Philippines (Gosliner et al. 2008), India ( Apte 2009; Remakrishna et al. 2010), Maldives ( Marcus & Marcus 1960), Seychelles, Madagascar (Gosliner et al. 2008), Tanzania ( Eliot 1903) and Mozambique ( King & Fraser 2014).

Remarks. Molecular data indicates that P. semperi is likely to represent a complex of species ( Wilson & Burghardt 2015). The morphotypes found in Mozambique were highly variable in colour with at least three different foot colourations present in Mozambican specimens, suggesting that there may be a species complex. Specimen MB28-004852 bears the same foot pattern found in “Group B” specimens ( Yorifuji, 2012) from northwestern Pacific. Additional studies are underway to verify if this population group contains cryptic/pseudocryptic species (Yorifuji M., pers. communication).
