New host record.

DISCUSSION: The new host-louse record of Halipeurus kermadecensis from Hawaiian petrels –referred to as Pterodroma phaeopygia sandwichensis by Dickinson (2003: 74) —is further evidence that the Galápagos and the Hawaiian petrels are different species and not subspecies, as shown by Browne et al. (1997) with a study of the genetic diversity and divergence of those petrels based on allozyme electrophoresis. The Galápagos petrel, Pterodroma phaeopygia phaeopygia , is host to Halipeurus noctivagus (see below), a louse species extremely different from H. kermadecensis .

Halipeurus kermadecensis has been found parasitising two species of Pterodroma petrels on Trindade Island, situated off the coast of Brazil in the South Atlantic Ocean: Pt. neglecta and Pt. arminjoniana arminjoniana . That is, if the identification by Imber (2004: 36) of a specimen kept in the USNM collection (Reg. 503731) as Pt. neglecta is accepted as valid; see Hammer et al. (2010) and discussion under H. heraldicus below.
