| Summary: | Marine dinoflagellate <i>Noctiluca scintillans</i> occurs in two forms, red and green, that overlap in distribution across the Arabian Sea and Southeast Asian coastal waters, particularly in Indonesia. However, limited genetic data on Indonesian <i>N. scintillans</i> cast uncertainty on their taxonomic status. In this study, we introduce the first 28S PCR primer set specifically designed for <i>Noctiluca</i> to enable sequence analysis. The Indonesian red-type <i>N. scintillans</i> (RNS) sequences show considerable divergence from other documented populations, suggesting a potentially adapted population in Jakarta Bay. Similarly, the RNS in Indonesia differ genetically from co-occurring green-type <i>N. scintillans</i> (GNS). Morphological differences were also observed between Indonesian and Japanese RNS, with Indonesian cells exhibiting a smaller size and rougher surface, in contrast to the larger size and smoother surface observed in Japanese specimens. |
