Chewing lice (Phthiraptera: Amblycera, Ischnocera) from Red Sea gulls with new host-parasite records

Knowledge about chewing lice from marine birds of the Red Sea is minimal. Five species of gulls were examined for
chewing lice in three different localities of the Saudi Arabian Red Sea coast. Two gull species were examined for lice for
the first time (Larus armenicus Buturlin, 1934 and Larus michahellis Naumann, 1840) and their lice represent new hostlouse
associations. Four species and two subspecies of lice were identified from 159 specimens collected. Actornithophilus
piceus lari (Packard, 1870) and Austromenopon transversum (Denny, 1842) (suborder: Amblycera), and Quadraceps
punctatus (Burmeister, 1838) and Saemundssonia lari (O. Fabricius, 1780) (suborder: Ischnocera) were recorded for the
first time from Saudi Arabia and Red Sea birds. Taxonomic and ecological notes, type hosts, data on specimens examined,
collecting localities, an identification key, and photographs of each species and subspecies are given.
