We describe a new species of Haemoproteus Kruse, 1890 from great frigatebirds (Fregata minor [Gmelin]) captured on Tern Island-French Frigate Shoals and Laysan Island in Hawaii. Parasite prevalence on Laysan Island (35%) was not significantly different than that of Tern Island (36%). On Laysan, prevalence was highest in juveniles (52%), followed by adult males (29%) and adult females (19%). Prevalence on Tern was 36% both for adult females and juveniles, and 28% for adult males. Parasitemia was low (mean < 2 parasites/10, 000 red blood cell). Parasitized red cells had significantly greater areas than unparasitized cells. We named this parasite Haemoproteus iwa after the Hawaiian name for frigatebirds (iwa). This is the first documentation of a hemoparasite from tropical pelagic seabirds in Hawaii and the first description of an endemic hemoparasite in the archipelago.
我们描述了一种来自红脚鲣鸟（Fregata minor [Gmelin]）的1890年克鲁斯血变虫属新物种，这些红脚鲣鸟捕获于夏威夷的燕鸥岛-法兰西护卫舰浅滩和莱桑岛。莱桑岛的寄生虫感染率（35%）与燕鸥岛（36%）没有显著差异。在莱桑岛，幼鸟的感染率最高（52%），其次是成年雄鸟（29%）和成年雌鸟（19%）。燕鸥岛成年雌鸟和幼鸟的感染率均为36%，成年雄鸟为28%。血虫血症水平较低（平均<2个寄生虫/10,000个红细胞）。被寄生的红细胞面积显著大于未被寄生的细胞。我们以夏威夷语中鲣鸟的名字（iwa）将这种寄生虫命名为伊瓦血变虫。这是夏威夷热带远洋海鸟血液寄生虫的首次记录，也是该群岛特有血液寄生虫的首次描述。
