【 摘 要 】

Multiple molecular phylogenetic studies have demonstrated that two Neotropical raptors, tiny hawk Accipiter superciliosus and its sister species semicollared hawk A. collaris, are not closely related to core Accipiter, and that A. superciliosus, at least, possesses osteological characters not replicated in the remainder of the genus. Based on these data, there is a need to recognise their distinctiveness at generic level. However, as recently noted in two global bird checklists, no name is available to accommodate them, so we provide a new nomen here. Furthermore, two Asian accipitrids, crested goshawk A. trivirgatus and its presumed closest relative Sulawesi goshawk A. griseiceps, are also phylogenetically distinctive; in this case the genus-group name Lophospiza is applicable. We also designate type species for two genus-group names (Hieraspiza and Eusparvius) currently in the synonymy of Accipiter, and, as an aid to future workers, we provide a synonymy of the genus Accipiter and a list of species currently included in Accipiter for which published molecular phylogenetic data are apparently lacking.
