Type host: Sterna fuscata Linnaeus, 1766 . Galápagos host: Sterna fuscata crissalis (Lawrence, 1872) . Galápagos locality: Isla Darwin. Galápagos references: Kellogg & Kuwana (1902) ; Kellogg (1906) ; Kellogg (1908: 25) ; Thompson (1939: 75) ; Linsley & Usinger (1966) ; Palma (1995) . Other significant references: Timmermann (1952b: 76 , figs 4–5; 1957: 71, pl. 9, figs a–b); Palma (1994b: 268) ; Palma (1996: 210) ; Price et al. (2003: 223) . Material examined: 9 males and 11 females (8 samples, EMEC ), but see Remarks . Remarks: From the Kellogg Collection, we examined eight males and 11 females labelled and reported by Kellogg & Kuwana (1902: 467–468) as “ Nirmus gloriosus ” from a number of hosts, and we have identified them as Quadraceps birostris . Twelve of those lice, including the lectotype of Nirmus gloriosus , are recorded from “ Sterna fuliginosa ” (= Sterna fuscata ), but their locality is Clipperton Island , not the Galápagos Islands. The remainder are recorded from incorrect hosts, from Galápagos localities. In addition, we examined one male labelled as “ Lipeurus helleri ” from “ Sula fuliginosa ” but reported by Kellogg (1906: 319) from Sterna fuliginosa , collected at Lat. 1 o N, Long. 93 o W, near Isla Darwin, where Sterna fuscata breeds ( Harris 1989: 118 ; Castro & Phillips 1996: 110 ). We have identified that male louse as Quadraceps birostris . At present, Sterna fuscata is the only known host of this louse species ( Price et al. 2003: 223 ).
