Conclusion
Various authors of descriptions of specimens of S. formosus (Müller & Schlegel, 1840) failed to study the early
literature on this species. As a result, the large variation in external characters and colouration remained unnoticed.
Due to the recent interest in this species for the aquarium trade, a more detailed study of the variation, including a
molecular study, was carried out by Pouyaud et al. (2003). These authors, however, based their study on a relatively
small sample of recent material, neglecting the fact that well-documented material from a number of localities is
available in various natural history museums. Pouyaud et al. designated a neotype for S. formosus, but overlooked
the fact that well-preserved type material of Osteoglossum formosum is available. Therefore, their designation of a
neotype is invalid.
