Lectotype ♂ in NHML ( Clay 1949: 816).

Type host: Anous stolidus ( Linnaeus, 1758) , in error (see Ryan & Price 1969a: 822).

Galápagos hosts: Sula granti Rothschild, 1902 ; Sula nebouxii excisa Todd, 1948 .

Galápagos localities: Isla Wolf; Isla Darwin; Isla Genovesa; Isla Seymour; Isla Baltra; Isla Española.

Galápagos references: Kellogg (1906); Kellogg (1908: 68); Thompson (1938b: 205); Emerson (1947: 135); Emerson (1964: 49); Linsley & Usinger (1966); Ryan & Price (1969a: 823).

Other significant references: Palma (1996: 124); Price et al. (2003: 107).

Material examined: 38 males, 40 females and 36 nymphs (13 samples, EMEC, MONZ) .

Remarks: From the Kellogg Collection, we examined ten specimens reported and labelled as “ Menopon singularis ” by Kellogg & Kuwana (1902: 485) and by Kellogg (1906: 321): two syntypes from an incorrect host, and eight specimens from two species of Sula (“ Sula variegata ” = Sula granti , and S. nebouxii ) and two incorrect hosts. We have identified them all as Eidmanniella albescens , a species known from several species of Sula (see Price et al. 2003: 107).

Ryan & Price (1969a: 822) erroneously listed “ 2 ♂ (type-specimens of M. singularis ), Anous stolidus , Galapagos”. The types of M. singularis are a female (the lectotype) and a nymph (paralectotype) with the original (type) locality given as “ Clipperton Island ”, as stated by Kellogg & Kuwana (1902: 485). However, as stated by Emerson (1947: 136), the figure included in Kellogg & Kuwana (1902) represents a male. Clipperton Island is not part of the Galápagos Archipelago but it was visited by the Hopkins Stanford Galapagos Expedition in their way to the Galápagos Islands (see Palma 1994b: 269).
