Abstract
Known to date as endemic to Mauritius Island (Mascarene Islands, Indian Ocean), Halichoeres pelicieri Randall et Smith, 1982 is recorded herewith for the first time from Reunion Island shore. This new observation expands the range of H. pelicieri to the western Mascarene Islands and strengthens the dispersal connection hypothesis from Mauritius to Reunion. It also emphasizes the importance to improve the prospecting effort on non-reef habitats in order to access to a better understanding of biodiversity and ecological functionalities of these often little studied habitats.
Highlights
The study of ichthyological diversity from Reunion island dates back to the late 18th century and resulted in identification of 984 fish species representing 164 families (Fricke et al 2009), new records are still quite common
This paper reports a sighting of a species that had not previously been recorded from Reunion, recorded during an environmental survey on the northeast coast of the island
This study provides a morphological characterization of a single observed individual, based on the photographic evidence
Summary
The study of ichthyological diversity from Reunion island dates back to the late 18th century and resulted in identification of 984 fish species representing 164 families (Fricke et al 2009), new records are still quite common. First record of a western Mascarene endemic, Halichoeres pelicieri (Actinopterygii: Perciformes: Labridae), from Reunion Island.
