Popis: The second part of the review of the subgenus Hirundichthys s.str. dealt with two nerito-oceanic species of the subgenus which have weakly pronounced “mirror” on the pectoral fins: H. oxycephalus and H. affinis. The validity of H. coromandelensis (Hornell, 1923) as a subspecies of H. oxycephalus is restored. A comparison of local populations showed that H. oxycephalus is a polytypic species and forms three subspecies: nominative H. oxycephalus oxycephalus from the Western Pacific and Eastern Indian Ocean, H. oxycephalus coromandelensis from the Arabian Sea, Bay of Bengal and adjoining waters of the Indian Ocean, and known by the only specimen from the waters of New Guinea H. oxycephalus frereensis ssp.n. Populations of H. affinis from the Western and Eastern Atlantic differ in the color of pectoral fins. Maps showing the geographical distribution of species and subspecies in the World Ocean are drawn up. A key for identification of species and subspecies belonging to the subgenus is proposed.
