The pitted stonefish (Erosa erosa), also known as the Pacific monkey-fish, is a species of venomous ray-finned fish, a stonefish be longing to the subfamily Synanceiinae of the family Scorpaenidae, the scorpionfishes and their relatives. It is the only species in the monotypic genus Erosa and is found in the eastern Indian Ocean and the western Pacific Ocean.
Taxonomy
The pitted stonefish was first formally described as Synanceia erosa in 1829 by the French zoologist Georges Cuvier with the type locality given as “Seas of Japan”. In 1839 William John Swainson placed it in the monotypic genus Erosa. The genus is considered, by some, to include the daruma stinger (Dampierosa daruma). The genus Erosa is classified within the tribe Synanceiini which is one of three tribes in the subfamily Synanceeinae within the family Scorpaenidae. However, other authorities regard Synanceiidae as a valid family and the Synanceiini as the subfamily Synanceiinae. Erosa means “gnawed” or “eaten away”, an allusion to the dimpled surfaces of the bones.
