Tetraroge

Tetraroge is a genus of ray-finned fishes, waspfishes belonging to the subfamily Tetraroginae, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives. These fishes are native to the Indian Ocean and the western Pacific Ocean.

==Taxonomy== Tetraroge was first described as a genus in 1860 by the German born British herpetologist and ichthyologist Albert Günther. In 1919 David Starr Jordan designated Apistus barbatus, which had been described by Georges Cuvier in 1829 from Java, as the type species of the genus. This genus is included in the subfamily Tetraroginae within the Scorpaenidae in the 5th edition of Fishes of the World however other authorities place that subfamily within the stonefish family Synanceiidae, while other authorities classify this subfamily as a family in its own right. The genus name Tetraroge combines tetra, which means "four", with rhogos, which means "clef", referring to the four clefts between the gill compared to 5 in Pentaroge, a synonym of Gymnapistes.
