Habitats. Subtropical tidal reefs and rocky reefs.

Occurrences. Ponta do Ouro and Zavora.

Geographic distribution. Indian Ocean. India (Ramakrishna et al. 2010), British Indian Ocean Territory (Debelius 1996; Yonow et al. 2002), Gulf of Oman (Fatemi & Attaran-Fariman 2015), Red Sea (Gosliner et al. 2008), Tanzania (Rudman 1977) and Mozambique.

Remarks. Gosliner et al. (2015) suggest an Indian Ocean distribution, however there are photographic records of specimens of similar appearance from Taiwan (Huang et al. 2015) and other locations in the Pacific (e.g. Rudman 2009a). Because H. nigrostriata is externally very similar to H. zephyra Gosliner & R. Jonson, 1999, the correct distribution of this species can only be confirmed with additional examination of specimens from the Pacific.
