Puffinus assimilis myrtae
Rapa Island, Tubaui Group.
Originally treated as a race of P. assimilis and subsequently often as a subspecies of P. auricularis, under latter arrangement also with P. newelli. However, the most recent molecular study found that myrtae is genetically more distinct from P. newelli than P. newelli is from P. auricularis#R, while morphological analysis of the few available specimens of myrtae indicate that it can be differentiated by effect size (from published data#R) for wing length vs the smaller of the other two taxa (P. auricularis), –6.56 (score 3); white vs dark undertail-coverts (at least 2); whitish inner webs to the remiges (at least 1); and a ‘white face’ ([ns]). Monotypic.
presumably C Pacific Ocean; breeds on Rapa I, in Austral Is (SC Pacific).
