A distinctive new species of Austromenopon from two species of shearwaters, Puffinus kuhlii (Scopoli) and Puffinus leucomelas (Temminick), is described herein. The new species is based on specimens collected from museum study skins and also from material lent to me by Dr. Theresa Clay, British Museum (Natural History) and the U.S. National Museum. I am indebted to Dr. Clay for the opportunity to examine material from the Meinertzhagen collection and to Dr. K. C. Emerson for reviewing this manuscript.
