Abstract
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.
Highlights
According to Price et al (2003), Brueelia Kéler, 1936 (Ischnocera) is the most speciose genus of parasitic lice within the Philopteridae (Phthiraptera), with about 280 species currently described
Using laboratory methods described by Bueter et al (2009) we sequenced a 382 base pair portion of the mitochondrial cytochrome oxidase I (COI) gene from each of the new Brueelia species, including one B. sueta sp. n. from P. pavoninus and three individuals of B. cicchinoi sp. n. from three different host species (T. viridis, T. melanurus, and P. pavoninus) to assess and document their genetic distinctiveness
Uncorrected p-distances between them range from 13.4–13.6%, whereas uncorrected p-distances within B. cicchinoi sp. n. from the five different host taxa Trogon viridis, T. melanurus, T. massena, T. melanocephalus, and Pharomachrus pavoninus are extremely small and range from 0–0.3%
Summary
According to Price et al (2003), Brueelia Kéler, 1936 (Ischnocera) is the most speciose genus of parasitic lice within the Philopteridae (Phthiraptera), with about 280 species currently described. Members of this genus parasitize the largest avian order, Passeriformes, but they occur on Piciformes and Coraciiformes. The only Brueelia species parasitic on trogons (Aves, Trogoniformes), B. insolita, was described by Cicchino (1983) from Trogon mexicanus Swainson, 1827 collected in Guatemala, and this taxon was transferred to Trogoninirmus Eichler, 1944 by Price et al (2003) without justification. This paper describes two additional species of Brueelia collected from Neotropical trogons
