Other significant references: Timmermann (1957: 56); Złotorzycka (1967); Palma (1996: 211); Price et al. (2003).

Material examined: 5 males and 5 females (1 sample, MONZ) .

Remarks: Pluvialis squatarola is a regular migrant to the Galápagos Islands ( Harris 1989: 91; Castro & Phillips 1996: 106) and the only known host of Quadraceps charadrii hospes . We regard this louse as a subspecies, instead of a full species as listed by Price et al. (2003), because a comparison of samples of Q. charadrii charadrii (ex Pluvialis apricaria ( Linnaeus, 1758)) and Q. charadrii hospes showed that differences are subtle, and mainly refer to dimensions.
