Type host: Pterodroma neglecta neglecta (Schlegel, 1863) . Galápagos host: Pterodroma phaeopygia (Salvin, 1876) . Galápagos locality: Isla Santa Cruz. Galápagos references: This paper. Other significant references: Timmermann (1959: 491 , fig. 5); Timmermann (1965: 129 , fig. 69); Price et al . (2003: 244) . Material examined: 68 males , 53 females and 23 nymphs (3 samples, MONZ ) . Remarks: Pterodroma phaeopygia is endemic to the Galápagos Islands . Although Dickinson (2003: 74) listed it as the subspecies Pterodroma phaeopygia phaeopygia , we regard it as a full species as well as Pterodroma sandwichensis (Ridgway, 1884) , following Browne et al. (1997: 814) . The material examined from Pterodroma phaeopygia differs in some features from typical Trabeculus fuscoclypeatus . However, we do not consider that such differences justify naming a new taxon; hence we qualify the samples from Pt. phaeopygia as “ sensu lato ”. This is the first record of Trabeculus fuscoclypeatus from the Galápagos Islands , and a new host-louse association for Pterodroma phaeopygia . Four other species of Pterodroma are listed in Price et al. (2003: 244) as hosts of this louse species.
