Lectotype ♀ in NHML ( Palma 2011: 29).

Type host: Hydrobates pelagicus ( Linnaeus, 1758) .

Galápagos hosts: Oceanites gracilis galapagoensis Lowe, 1921 ; Oceanodroma tethys tethys (Bonaparte, 1852) ; Oceanodroma castro (Harcourt, 1851) .

Galápagos localities: Isla Darwin; Isla Wolf; Isla Isabela; Isla Fernandina; Isla Plaza; Islote Corona del Diablo (near Isla Floreana).

Galápagos references: Kellogg & Kuwana (1902); Kellogg (1906); Kellogg (1908: 39, 41); Ewing (1924: 84); Thompson (1939); Edwards (1961); Linsley & Usinger (1966); Palma (2011: 28).

Other significant references: Timmermann (1961a: 413, figs 9–10); Timmermann (1965: 153, fig. 94, pl. 7, figs 3–4); Palma (1996: 186); Price et al. (2003: 188).

Material examined: 43 males, 34 females and 69 nymphs (12 samples, EMEC, MONZ) .

Remarks: This species was placed in the subgenus Synnautes Thompson, 1936 in many publications, but Palma (2011: 16) has synonymised Synnautes under the nominate subgenus Halipeurus . Palma (2011: 28) recorded Halipeurus pelagicus from nine species of storm petrels, including the three Galápagos hosts listed above. From the Kellogg Collection, we examined the lectotype male, one paralectotype female and one paralectotype male of Lipeurus languidus , plus five specimens reported by Kellogg (1906: 319) as “ Lipeurus languidus ” from Oceanites gracilis , and we have identified them as Halipeurus pelagicus .
