Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, Leninskii pr. 33, 119071, Moscow, Russia aut Critical analysis of results of the revision of the genus Chiasmodon made by M.R.S. Melo (2009) and a characteristic of new form C. niger -complex from the Indian Ocean (perciformes: chaismodontidae) [Elektronische Daten] [A. Prokofiev] Results of the revision of black swallowers (Chiasmodon) made by Melo (2009) are reconsidered. It is shown that separation of species by this author is based on individually varying characters investigated by this author on a limited number of fish, and some conclusions made in this study are based on factual mistakes. Validity of C. lavenbergi Prok. is restored, and C. asper Melo is included to its synonymy. It is shown that C. pluriradiatus Parr, as all other nominal species of the genus Chiasmodon, should be place in C. niger s. lato. Variation of C. niger-complex by dentition of gill arches and by some other meristic characters is pointed out. By armament of the gill apparatus, along with the typical form, forms α and β are discerned. The latter form is described in detail by two specimens from the eastern part of the Indian Ocean. It is found that form β corresponds to characters of the holotype of C. braueri while form α does not correspond to neither of the nominal taxa, attributed to C. niger s. l.
