This paper reports the first record of the species Ostorhinchus holotaenia Regan, 1905 from Madagascar. This species was identified during a survey of marine introduced species, carried out in June 2018 in and close to the port of Toamasina, on behalf of the Indian Ocean Commission. However, although the question of a possible introduction of the species by maritime traffic may be raised, this observation is probably more of a range extension of the species, already identified as Indo-West Pacific distribution. This study confirms the need of continuing sampling, particularly of habitats usually considered as of secondary scientific interest, with the aim of completing the current lists of species.
