A neotype is described for the Indo-Pacific damselfish Neopomacentrus azysron (Bleeker). Bleeker’s holotype is not extant, and his illustration bears a greater resemblance to N. sindensis (Day) than the species that recent authors have identified as as N. azysron. The neotype conforms to Bleeker’s description. The Indian Ocean damselfish previously identified N. azysron is described as a new species, N. sororius, distinct chiefly in colour from the western Pacific N. azysron.
