Abstract: Seven species of chewing lice (Insecta: Phthiraptera) were found on five species of bulbuls (Passeriformes: Pycnonotidae) in northern Vietnam. Three new species of the genera Brueelia and Philopteroides are described; they and their type hosts are: Brueelia flavala ex Hemixos flavala Blyth, 1845 B. cucphuongensis ex Pycnonotus finlaysoni Strickland, 1844 and Philopteroides flavala ex Hemixos flavala Blyth, 1845. First records of chewing lice from Hemixos castanonotus Swinhoe, 1870 and Iole propinqua (Oustalet, 1903), and a new host record for Myrsidea ochracei and Sturnidoecus sp. are also included.
TL;DR: Fifteen of 16 loci were successfully amplified in the ashy bulbul, with rich polymorphism in 15 individuals tested, which will be useful in population genetics, conservation and phylogenies of the chestnut bulbul.
Abstract: A set of primers to amplify 16 microsatellite DNA loci was developed for the Chestnut Bulbul Hemixos castanonotus and the cross-amplification of these loci was tested in a closely related species, the ashy bulbul Hemixos flavala. A total of 30 Chestnut Bulbul individuals were genotyped. An average of 6.5 alleles per locus (2–12 alleles) was detected. The expected heterozygosity values ranged from 0.218 to 0.888. Four loci significantly deviated from Hardy–Weinberg equilibrium after Bonferroni correction. No significant linkage disequilibrium was detected. Fifteen of 16 loci were successfully amplified in the ashy bulbul, with rich polymorphism in 15 individuals tested. These markers will be useful in population genetics, conservation and phylogenies of the chestnut bulbul.
