Neotype ♂ in NHML ( Clay & Hopkins 1960: 39, pl. 2, fig. 3).

Type host: Mergus serrator Linnaeus, 1758 .

Galápagos host: Anas bahamensis galapagensis (Ridgway, 1889) .

Galápagos localities: Isla Santa Cruz; Isla Santiago.

Galápagos references: Kellogg (1906); Linsley & Usinger (1966).

Other significant references: Clay & Hopkins (1960: 37, figs 59–61); Kéler (1960); Palma (1996: 155); Price et al. (2003: 145).

Material examined: 3 males, 3 females (1 sample, MONZ) .

Remarks: The record of a single female “ Docophorus icterodes Nitzsch ” in Kellogg & Kuwana (1902: 462) is from an incorrect host from Clipperton Island, but it is likely to be the result of a contamination from a Galápagos host (see Palma 1994b); we examined this female and have identified it as Anatoecus icterodes . The material from “Indefatigable Id.” (= Santa Cruz Island) reported by Kellogg (1906: 317) was not found in the Kellogg Collection at EMEC. This louse species is parasitic on a very large number of anatid species belonging to several genera ( Price et al. 2003: 145), but Kellogg’s (1906: 317) record of Anatoecus icterodes (as “ D. icterodes ”) from Anas bahamensis galapagensis (as “ Anas versicolor ”) was not included in Price et al. (2003), probably because the authors were not aware of the correct identity of the host.
