Dibrachichthys
''Dibrachichthys'' is a monospecific genus belonging to the family Tetrabrachiidae, the four-armed frogfishes. The only species in the genus is ''Dibrachichthys melanurus'', the twoarm humpback anglerfish, which is found in the eastern Indian and western Pacific Oceans. Taxonomy ''Dibrachichthys'' was first proposed as a genus in 2009 by Theodore Wells Pietsch III, Jeffrey W. Johnson and Rachel J. Arnold when they described ''Dibrachichthys melanurus''. The type locality of the new species was given as 11°06.9'S, 142°51.9'E, northeast of Ussher Point on the Cape York Peninsula in Queensland. This genus is one of two genera, both monotypic, in the family Tetrabrachiidae. The Tetrabrachiidae is classified within the suborder Antennarioidei within the order Lophiiformes, the anglerfishes. Etymology ''Dibrachichthys'' combines ''di'', meaning "two", ''brachium'', meaning "arm", and ''ichthys'', which means "fish". This is an allusion to the possession of a single undivide ...

Tetrabrachiidae
Tetrabrachiidae, or the four-armed frogfishes or doublefin frogfishes, is a small family of marine ray-finned fishes belonging to the suborder Antennarioidei in the order Lophiiformes, the anglerfishes. These fishes are found in relatively shallow waters of the eastern Indian Ocean and western Pacific Ocean. Taxonomy Tetrabrachiidae was first proposed as a subfamily, the Tetrabrachiinae, of the family Antennariidae in 1912 by the English ichthyologist Charles Tate Regan with only a single genus included, ''Tetrabrachium'', a monospecific genus which had been proposed by Albert Günther in 1880. In 2009 a second monospecific genus, '' Dibrachichthys'', was added to the family when it was described by Theodore Wells Pietsch III, Jeffery W. Johnson and Rachel J. Arnold. The Tetrabrachiidae is classified within the suborder Antennarioidei within the order Lophiiformes, the anglerfishes. This family is regarded, with its sister taxon the Antennariidae, as the most derived clade wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
