    Introduction: I here comment on the phylogenetic position and generic status of the rare and threatened Abbott's Booby Papasula abbotti. I argue that the current genus name of this species was erected from an incorrect interpretation of a phylogenetic hypothesis and a straightforward decision about its generic placement cannot be made, given the conflicts regarding the species' closer phylogenetic relationships. Methods: I examined three published hypotheses of phylogenetic relationships for Sulidae (one based on phenotypic and two on molecular data), following Hennig’s principle of reciprocal illumination, wherein a given hypothesis is evaluated by the extent to which it agrees with competing hypotheses. Results and discussion: There is a considerable degree of congruence among the examined cladograms, the main .. Read More»
