They are slender and elongate (body depth 2.7–3.0 in SL), and usually occur over outer reef slopes in midwater aggregations feeding on zooplankton (Allen and Emery, 1973 ; Allen and Randall, 1974; Allen, 1975a; Allen and Larson, 1975). Given their overall similarity, the genus has been stable since its inception (Allen and Randall, 1974). Allen and Larson (1975), in describing the most recent addition to the genus, stated that all four are closely related. Our phylogeny agrees ( Fig. 1 ), displaying strong bootstrap support (100%) for the monophyly of Pomachromis .
