Two new species of the feather mite family Gabucinidae (Acari: Astigmata) are described from birds of the family Troglodytidae (Passeriformes) from Central America: Piciformobia cinnycerthiae sp. nov. from Cinnycerthia unirufa (Lafresnaye) in Ecuador, and P. henicorhinae sp. nov. from Henicorhina leucosticte (Cabanis) in Costa Rica. These are the first records of mites of the genus Piciformobia Gaud et Atyeo, 1975 from passerine hosts. A renewed diagnosis of the genus Piciformobia and key to all known species are provided.
Four new species of the feather mite subfamily Pterodectinae (Proctophyllodidae) are described from passerine birds examined in Senegal: Dolichodectes gymnoris sp. nov. from the Russet-browed Bush-sparrow Gymnoris dentata (Sundevall, 1850) (Passeridae), Montesauria plocei sp. nov. from the Village Weaver Ploceus cucullatus (Muller, 1776) (Ploceidae), M. zosteropis sp. nov. from the African Yellow White-eye Zosterops senegalensis Bonaparte, 1850 (Zosteropidae), and Proterothrix terpsiphone sp. nov. from the African Paradise-flycatcher Terpsiphone viridis (Muller, 1776) (Monarchidae). Brief notes on systematics and host associations of the pterodectine genera Dolichodectes Park et Atyeo, 1971, Montesauria Oudemans, 1905, and Proterothrix Gaud, 1968 are also given.
We studied blood parasites in wild birds within Hitoy Cerere Biological Reserve and Barbilla National Park in Costa Rica during the rainy season of 2004. We examined blood samples from 248 and 114 birds, respectively. Protozoan parasites of the genus Haemoproteus as well as microfilariae were found. Prevalence of Haemoproteus in birds was 0.8% and 4.4% in Hitoy Cerere and Barbilla, respectively, and differences were significant. Prevalence of infection by microfilariae was 8.1% and 3.5%, respectively, however, differences were not significant. Based on morphological characteristics, we divided microfilariae into two groups and nine morphotypes. In Hitoy Cerere, there were microfilariae of all nine morphotypes whereas in Barbilla we only found two morphotypes.
A total of 170 wild birds from Senegal, belonging to 48 species and 9 orders, were searched for lice in 2005 and 2007. Chewing lice were found on 58 birds of 18 species and 5 orders (Columbiformes, Cuculiformes, Coraciiformes, Galliformes and Passeriformes). Twenty-two species of chewing lice of 13 genera were determined. Other nine samples of chewing lice that represent a new host-parasite association were determined at generic level only, because only one sex or nymph of these lice were found. Our records represent the first louse records from passerines Camaroptera brachyura (Cisticolidae), Chalcomitra senegalensis (Nectariniidae), Corvinella corvina (Laniidae), Laniarius barbarus (Malaconotidae), Prinia erythroptera (Cisticolidae) and Turdus pelios (Turdidae). Descriptions and illustrations are given for Brueelia chalcomitrae Najer et Sychra sp. nov. ex Chalcomitra senegalensis (Nectariniidae), Brueelia priniae Najer et Sychra sp. nov. ex Prinia subflava (Cisticolidae), and Philopteroides terpsiphoni Najer et Sychra sp. nov. ex Terpsiphone viridis (Monarchidae).
