Revision of Genus Melamphaes (Melamphaidae). II. Multi-Raker Species: M. polylepis, M.falsidicus sp. nova, M. pachystomus sp. nova, M. macrocephalus, M. leprus

摘要

The second part of the publication is devoted to the Melamphaes species (family Melamphaidae), which are characterized by 20 and more rakers on the first gill arch, by seven soft rays in the ventral fin, by absence of a temporal spine, by 14—15 raysin the pectoral fin, and by 11 abdominal vertebrae. M. polylepis is characterized by circumtropical range (Atlantic Ocean, Indian Ocean, western and central Pacific Ocean). Newly described species M. falsidicus is described from the northern Atlantic Ocean, where it was sampled between 34°N and 58°N. Before, this species was defined as M. microps. Another newly described species, M. pachystomus, is described along the Peruvian Coast. M. macrocephalus is redescribed. This species inhabits the eastern tropical Pacific Ocean (approximately between 30°N and 23°S). One of the studied specimens of M. macrocephalus was characterized by larger body size (SL =128 mm) than was described before for this species. M. lepras is known currently by single findingsfrom the eastern tropical Atlantic Ocean (between 11 °N and 4°S). This species was also found in the samples obtain in the Gulf of Guinea.
