Two new species of Brueelia are described and illustrated. These new species and their type hosts are: Brueelia sueta ex Pharomachrus pavoninus (Spix, 1824), the Pavonine Quetzal and Brueelia cicchinoi ex Trogon viridis Linnaeus, the White-tailed Trogon. Both new species differ from the only Brueelia described on Trogon mexicanus by many morphological features, including those present in the male genitalia and female vulvar margin. Partial sequences of the mitochondrial cytochrome oxidase I (COI) gene for these two new species differ from one another by 13.6% uncorrected p-distance. Whereas Brueelia cicchinoi is only 0.3% divergent from previously published COI sequences identified as Brueelia sp. from the Mexican Trogon melanocephalus Gould, 1936 and Trogon massena Gould, 1938. We also found Brueelia cicchinoi on Trogon melanurus, Trogon collaris and Pharomachrus pavoninus. Thus Brueelia cicchinoi is found on multiple trogoniform hosts across an extremely large geographic distribution and has one of the largest number of host associations among Brueelia species.
描述并图示了布鲁氏鸟虱属的两个新物种。这些新物种及其模式宿主分别是：绿咬鹃布鲁氏鸟虱（Brueelia sueta），寄生于绿咬鹃（Pharomachrus pavoninus，斯皮克斯，1824）；奇氏布鲁氏鸟虱（Brueelia cicchinoi），寄生于白尾美洲咬鹃（Trogon viridis，林奈）。这两个新物种在许多形态特征上与仅在纯色美洲咬鹃（Trogon mexicanus）上描述过的布鲁氏鸟虱不同，包括雄性生殖器和雌性外阴边缘的特征。这两个新物种的线粒体细胞色素氧化酶I（COI）基因的部分序列，未校正的p距离彼此相差13.6%。而奇氏布鲁氏鸟虱与先前发表的被鉴定为布鲁氏鸟虱属的COI序列相比，仅相差0.3%，这些序列来自1936年的黑头美洲咬鹃（Trogon melanocephalus，古尔德）和1938年的马塞纳美洲咬鹃（Trogon massena，古尔德）。我们还在黑美洲咬鹃（Trogon melanurus）、白领美洲咬鹃（Trogon collaris）和绿咬鹃上发现了奇氏布鲁氏鸟虱。因此，奇氏布鲁氏鸟虱在极为广泛的地理分布范围内寄生于多种咬鹃科宿主上，并且在布鲁氏鸟虱属物种中拥有最多的宿主关联之一。
