Lectotype ♂ in EMEC ( Carriker 1957: 102 ). Type host: Fregata magnificens Mathews, 1914 . Galápagos host: Fregata magnificens Mathews, 1914 . Galápagos localities: Isla Wolf; Isla Seymour; Isla Santa Cruz; Isla Española. Galápagos references: Kellogg (1906) ; Kellogg (1908: 40) ; Linsley & Usinger (1966) . Other significant references: Carriker (1957: 102) ; Emerson (1958: 513) ; Price et al. (2003: 208) . Material examined: 22 males , 14 females and 51 nymphs (3 samples, MONZ ) . Remarks: We regard this taxon as a subspecies because the differences between the populations of Pectinopygus from Fregata magnificens and Fregata minor refer to dimensions only. Therefore, in this case, we do not follow Price et al. (2003: 208) .
