Phylogenetic Relationships of Aracanin Genera of Boxfishes (Ostraciidae: Tetraodontiformes)

Abstract
A cladistic analysis of the external characters, osteology and myology of the seven genera currently assigned to the ostraciid (trunkfishes and boxfishes) subfamily Aracaninae (boxfishes) results in our proposal of its division into two tribes, the Aracanini (Aracana, Strophiurichthys, Anoplocapros, Caprichthys and Capropygia) and the Kentrocaprini (Kentrocapros and Polyplacapros). In the case of the Aracanini, the phylogeny can be derived from the classification either from sequencing or from the numerical suffix method. Evidence is presented which corroborates the hypotheses that: a) the Aracaninae is monophyletic; b) the Ostraciinae is monophyletic; c) the Aracaninae and Ostraciinae are sister groups (the Ostraciidae); d) the Balistidae is monophyletic; and e) the Balistidae and Ostraciidae are sister groups.
