A revision of the genusPerineus(Phthiraptera: Philopteridae)

Abstract
Six species of the genus Perineus Thompson, 1936 are recognised, including one new species. These, together with their hosts, are: P. nigrolimbatus (Giebel, 1874) on Fulmarus glacialis glacialis, F. glacialis auduboni, F. glacialis rodgersii, and F. glacialoides; P. concinnus (Kellogg & Chapman, 1899) on Diomedea albatrus, D. immutabilis, and D. nigripes; P. concinnoides Kéler, 1957 on Diomedea exulans exulans, D. exulans chionoptera, D. epomophora epomophora, and D. epomophora sanfordi; P. oblongus Kéler, 1957 on Diomedea irrorata; P. circumfasciatus Kéler, 1957 on Diomedea melanophrys melanophrys, D. melanophrys impavida, D. cauta cauta, D. cauta salvini, D. cauta eremita, D. chrysostoma, D. chlororhynchos, D. butteri, Phoebetria palpebrata, and P. fusca; Perineus macronecti new species on Macronectes halli (type host) and Macronectes giganteus. A key and illustrations are provided to both male and female adults of all the species. Lectotypes are designated for two species already synonymised; these are Lipeurus mutabilis Piaget, 1880 and Lipeurus celer Kellogg, 1896.
