O presente estudo teve como objetivos investigar a comunidade de ectoparasitos associada a aves Mata do Olho D \água, localizada no munic\ípio de Maca\íba, Rio Grande do Norte, BR, sua estrutura e a influ\ência de vari\áveis ambientais e morfol\ógicas dos hospedeiros, al\ém de averiguar prefer\ências de microh\ábitat pelas esp\écies de \ácaros de pena e mal\ófagos em associadas \às aves em estudo. Foram examinados 172 indiv\íduos pertencentes a 38 esp\écies de aves Passeriformes e n\ão-Passeriformes. S\ão reportados 12 novos registros geogr\áficos para o Brasil e 11 associa\ç\ões ainda n\ão conhecidas com hospedeiros de \ácaros de pena e mal\ófagos. Foi detectada rela\ç\ão significativa entre abund\ância de mal\ófagos e as vari\áveis comprimento total (r= 0,29; p\<0,05) e c\úlmen exposto (r= 0,38; p\<0,05) dos hospedeiros. Uma componente principal (CP1) respons\ável por 90,1\% da varia\ç\ão morfol\ógica dos hospedeiros foi significativamente influente sobre a abund\ância de mal\ófagos (p\<0,05), indicando que caracter\ísticas morfol\ógicas dos hospedeiros podem estar influenciando positivamente a abund\ância desses ectoparasitos. Frequ\ência significativamente maior de indiv\íduos com altas cargas de mal\ófagos foi dectada durante o per\íodo de seca (x\²= 8,5; p\<0,05), corroborando estudos que prop\õem que aves de ambientes \áridos sofrem tanta press\ão parasit\ária quanto aquelas de ambientes \úmidos. An\álises de modelos nulos de coocorr\ência e sobreposi\ç\ão de nicho apontaram alto grau de estrutura nas assembleias de \ácaros e mal\ófagos, quando comparadas com outros grupos, e prefer\ências no uso de microh\ábitats pelos t\áxons identificados. Estes resultados corroboram teorias ecol\ógicas nos sistemas parasito-hospedeiro, contribuem para o conhecimento dos ectoparasitos associados \às aves neotropicais e apontam a necessidade de estudos experimentais, assim como maior aprofundamento na biologia desses artr\ópodos

This study to aimed investigate the community of ectoparasites associated with birds in the Mata do Olho D \água, in the municipality of Maca\íba, Rio Grande do Norte (RN), Brazil, its structure and the ambiental and hosts influential variables on it, and to verify microhabitats preferences by species of chewing lice and feather mites. We examined 172 individuals belonging to 38 species of Passeriformes and non-Passeriformes. 12 new geographic records are reported and 11 host-parasite associations not yet known for chewing lice and feather mites species. Significant relationship was found between the abundance of chewing lice and the variables total length (r = 0.29, p \<0.05) and exposed culmen (r = 0.38, p \<0.05) of the hosts. A principal component (PC1) accounted for 90.1\% of the hosts morphological variation was significantly influential on the abundance of chewing lice (p \<0.05), indicating that the morphological characteristics of the hosts may be positively influencing the abundance of these ectoparasites. Significantly higher frequency of individuals with high loads of chewing lice was detected during the dry period (x \² = 8.5, p \<0.05), corroborating studies that propose that birds of arid environments suffer as much pressure as those of parasitic humid environments. Analyses of null models of co-occurrence and niche overlap showed a high degree of structure in the feather mites and chewing lice assemblies, when compared with other groups, and preferences in the use of microhabitats by taxa identified. These results corroborate ecological theories in host-parasite systems, contribute to the knowledge of ectoparasites associated with neotropical birds, and the need for experimental studies, as well as further deepening the biology of these arthropods

The Riverine Barriers Hypothesis (RBH) posits that tropical rivers can be effective barriers to gene flow, based on observations that range boundaries often coincide with river barriers. Over the last 160 years, the RBH has received attention from various perspectives, with a particular focus on vertebrates in the Amazon Basin. To our knowledge, no molecular assessment of the RBH has been conducted on birds in the Afrotropics, despite its rich avifauna and many Afrotropical bird species being widely distributed across numerous watersheds and basins. Here, we provide the first genetic evidence that an Afrotropical river has served as a barrier for birds and for their lice, based on four understory bird species collected from sites north and south of the Congo River. Our results indicate near-contemporaneous, Pleistocene lineage diversification across the Congo River in these species. Our results further indicate differing levels of genetic variation in bird lice; the extent of this variation appears linked to the life-history of both the host and the louse. Extensive cryptic diversity likely is being harbored in Afrotropical forests, in both understory birds and their lice. Therefore, these forests may not be \“museums\” of old lineages. Rather, substantial evolutionary diversification may have occurred in Afrotropical forests throughout the Pleistocene, supporting the Pleistocene Forest Refuge Hypothesis. Strong genetic variation in birds and their lice within a small part of the Congo Basin forest indicates that we may have grossly underestimated diversity in the Afrotropics, making these forests home of substantial biodiversity in need of conservation.

A total of 166 individuals from 10 bird species belonging to the family Turdidae were examined for chewing lice in Costa
Rica during 2004, 2009 and 2010. A total of 12 species of the louse genus Myrsidea were collected from 54 birds,
including four previously named, seven new undescribed species, and one identified as Myrsidea sp. Names, descriptions
and illustrations are given for the seven new species of Myrsidea. They and their type hosts are: Myrsidea assimilis sp.
nov. ex Turdus assimilis (Cabanis, 1850), M. cerrodelamuertensis sp. nov. ex Catharus gracilirostris (Salvin, 1865), M.
hrabaki sp. nov. ex Myadestes melanops (Salvin, 1865), M. obsoleti sp. nov. ex Turdus obsoletus (Lawrence, 1862), M.
quinchoi sp. nov. ex Catharus frantzii (Cabanis, 1861), M. tapanti sp. nov. ex Catharus fuscater (Lafresnaye, 1845), and
M. tapetapersi sp. nov. ex Turdus nigrescens (Cabanis, 1861). Records of four named and one unidentified species of
Myrsidea from other Costa Rican thrushes are also given and discussed

Ten new species of Myrsidea Waterston, 1915 parasitic on members of the avian families Formicariidae, Thraupidae,\ Tyrannidae, Troglodytidae and Icteridae are described herein. They and their type hosts are M. isacantha sp. n. ex Chamaeza nobilis\ Gould, M. circumsternata sp. n. ex Formicarius colma Boddaert (Formicariidae); M. cacioppoi sp. n. ex Lanio fulvus (Boddaert),
M. brasiliensis sp. n. ex Tangara chilensis (Vigors), M. saviti sp. n. ex Tangara schrankii (Spix) (Thraupidae), M. rodriguesae sp. n.\ ex Cnipodectes subbrunneus (Sclater), M. cnemotriccola sp. n. ex Cnemotriccus fuscatus (Wied-Neuwied), M. lathrotriccola sp. n.\ ex Lathrotriccus euleri (Cabanis) (Tyrannidae), M. faccioae sp. n. ex Cyphorhinus arada transfluvialis (Todd) (Troglodytidae), and\ M. lampropsaricola sp. n. ex Lampropsar tanagrinus (Spix) (Icteridae). Among these are two new Myrsidea species described from\ the avian family Formicariidae, which previously had only a single described Myrsidea species, and a new host record for M. cinnamomei\ Dalgleish et Price, 2005 ex Attila citriniventris Sclater. Analysis of mitochondrial cytochrome oxidase I sequences for these\ and other neotropical Myrsidea species provides an assessment of their phylogenetic relationships and indicates that all of these\ newly described species are genetically distinct. We also put these descriptions into context by estimating the potential number of\ unnamed Myrsidea species in Brazil, given the known diversity of potential hosts and typical levels of host specificity for Myrsidea\ species. Our estimate indicates that Brazilian Myrsidea species diversity is likely more than an order of magnitude greater than the\ number of described Myrsidea species known from Brazil, highlighting the need for future work on this megadiverse ectoparasite\ genus.

This study was performed to detect chewing lice on Magpie, between the dates of August 2011-February 2012 in Konya, Central Anatolian Region of Turkey. For this aim, 64 Magpie individuals were examined for the louse. In order to sample chewing lice, the feathers of the birds were carefully examined macroscopically. All lice were collected and placed in tubes with 70\% alcohol, cleared in 10\% KOH mounted in Canada balsam on slides and identified under a light microscope. Of birds examined, 20 out of 64 (31.25\%) were infested with at least one chewing louse species. Three lice species which belongs to the three genera, Menacanthus eurysternus (Burmeister, 1838), Myrsidea picae (Linnaeus, 1758) and Brueelia biocellata (Piaget, 1880) were found. Brueelia biocellata is the first ever recorded in Turkey.
