After the transfer of M. costata to Skeletonema (Cleve 1873), ﬁve more species were described in the genus based on morphological characters: S. tropicum, S. sub-salsum, S. potamos (Weber) Hasle, S. cylindraceum Prosh- An assessment of the taxonomy of S. costatum-like species with the description of four new species. Recent studies have shown that the cosmopolitan diatom Skeletonema costatum sensu lato is composed of several morphologically and genetically distinct species. Skeletonema costatum has been widely used both in extensive and intensive hatchery systems of Marsupenaeus japonicus (Hudinaga, 1942; 1969) and Penaeus monodon (Su et al., 1990). Abstract After the recent revisions of the diatom genus Skeletonema, our knowledge on its diversity has greatly improved, although its taxonomy has become more complicated, especially with the descriptions of cryptic or semicryptic species, which make species recognition difficult.
