Pomachromis .

— The reef-damsels of the genus Pomachromis are a morphologically distinct group of four species distributed across the Indo-West Pacific. 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 .

The phylogenetic relationships of damselfishes (Teleostei: Pomacentridae): (A) outgroup taxa; (B) subfamilies Microspathodontinae and Glyphisodontinae; (C) subfamily Chrominae; (D) subfamily Pomacentrinae (part I); (E) subfamily Pomacentrinae (part II). The phylogeny is based on the maximum-likelihood topology with the best log likelihood score (ln L ¼ –45,4518.728) recovered from ten independent maximum-likelihood analyses of a data matrix composed of 462 taxa and 6,865 nucleotides. Bootstrap values from 1,000 ultrafast replicates are displayed for each node
