The scorpionfish subfamily Setarchinae is revised on a worldwide basis. The subfamily is redefined and three genera and four species are recognized. Lioscorpius longiceps Günther is treated as a senior synonym of Macroscorpius pallidus Fowler after designation of
a lectotype of the former. The genus Ectreposebastes Garman is referred to the subfamily, and E. imus Garman is reported for the first time from the Atlantic Ocean. Two species of Setarches are recognized, S. longimanus (Alcock) from the western Pacific and Indian
oceans and S. guentheri Johnson from the Atlantic, Indian, and western Pacific oceans. Descriptions and a key are included.
The Bulletin of Marine Science is dedicated to the dissemination of high quality research from the world's oceans. All aspects of marine science are treated by the Bulletin of Marine Science, including papers in marine biology, biological oceanography, fisheries, marine affairs, applied marine physics, marine geology and geophysics, marine and atmospheric chemistry, and meteorology and physical oceanography.
