Lectotype ♂ in EMEC (designated below).

Type host: Progne modesta Gould, 1838 .

Galápagos host: Progne modesta Gould, 1838 .

Galápagos localities: Isla Isabela; Isla Santa Cruz.

Galápagos references: Kellogg & Kuwana (1902); Kellogg (1906); Kellogg (1908: 11); Ewing (1924: 82); Thompson (1939: 16); Linsley & Usinger (1966).

Other significant references: Hopkins & Clay (1952: 281); Price et al. (2003).

Material examined: 5 males, 10 females and 2 nymphs (2 samples, EMEC) .

Remarks: This louse species and its host are endemic to the Galápagos Islands. From the Kellogg Collection, we examined the “ lectotype ” male, seven “ paralectotypes ” and four additional specimens of Docophorus breviformis , all from the type host. Also, we examined three further females of Philopterus breviformis , two labelled and reported by Kellogg & Kuwana (1902: 463, 467) as Docophorus breviformis from Geospiza fortis , and one as “ Docophorus insulicola ” from Geospiza fuliginosa . We regard these latter females as contaminants.

One label of the “ lectotype ” slide of Docophorus breviformis reads “ T. Clay det. / LECTOTYPE ♂ ”. However, we have been unable to find the formal published designation of this specimen as the lectotype. Therefore, we herewith designate the male on Kellogg Collection slide 1105a “fig-d” as the lectotype of Docophorus breviformis , with the remaining 9 specimens from Progne modesta (2 males, 5 females and 2 nymphs on slides 1136, 1145a, 1150a,b, 1153) as paralectotypes, all deposited in EMEC .
