Title: A systematic treatment of the reef-fish Family Pomacanthidae (Pisces: Perciformes)

Abstract: Portions of a relational data model developed to manage information relevant to taxonomic names and concepts are described. The core entities of this model include Agents, References, and Assertions (along with their associated Protonyms). I also illustrate how these entities can serve as a foundation for taxonomic names and concepts as integrated with other datasets, such as specimens, observations, geographic distributions and character matrices. The primary data content source used to populate and test the data model is derived from a systematic revision of the reef-fish family Pomacanthidae. An intuitive, feature-rich software application based on Microsoft Access® has also been developed in conjunction with this data model. Eighty-four species among seven genera (Apolemichthys, Centropyge, Chaetodontoplus, Genicanthus, Holacanthus, Pomacanthus, and Pygoplites) are regarded as valid within the Pomacanthidae. Three of these genera are further classified among nine subgenera (nominotypical Centropyge with Paracentropyge and Xiphypops; nominotypical Holacanthus with Angelichthys; and nominotypical Pomacanthus with Acanthochaetodon, Arusetta, and Euxiphipops). The generic names Desmoholacanthus, Plitops, Pomacanthodes, Pomacanthops, and Sumireyakko are treated as a junior synonyms of Apolemichthys, Holacanthus, Pomacanthus, Arusetta, and Paracentropyge, respectively. The species Holacanthus venusta is regarded as belonging to the subgenus Paracentropyge. The classification of pomacanthid genera and subgenera is mostly consistent with a cladogram produced from a parsimony analysis based on 37 characters (27 informative characters). The genus Centropyge Kaup 1860 contains 51 nominal species, of which 32 are treated as valid. The species are grouped into three subgenera: the nominotypical C. (Centropyge) with 23 species, C. (Paracentropyge) with three species, and C. (Xiphypops) with six species. Paradiretmus is treated as junior synonym of Centropyge, though its single species (P. circularis) is considered unidentifiable to species. The nominotypical subgenus C. (Centropyge) is divided into six informal species "complexes," defined by various morphological character combinations. Eleven examples of probable hybrids within the Pomacanthidae are reviewed; five in Centropyge; one in Holacanthus, and four in Pomacanthus. An additional four examples of possible pomacanthid hybrids are described, two in Centropyge and two in Chaetodontoplus. The nominal species Apolemichthys armitagei represents hybrid forms between A. trimaculatus and A. xanthurus.
