Valim, Michel P.;
Papéis Avulsos de Zoologia (S?o Paulo) , 2009, DOI: 10.1590/S0031-10492009001700001
Abstract: the type specimens of 142 nominal species of chewing and sucking lice (insecta: phthiraptera: amblycera, ischnocera and anoplura) held in the museu de zoologia da universidade de s?o paulo, brazil (mzusp) are listed. the list includes species in the families: menoponidae and gyropidae (suborder amblycera); philopteridae (including species initially described in heptapsogastridae) and trichodectidae (suborder ischnocera); and hoplopleuridae (suborder anoplura). the following type categories are represented in the collection: holotype, allotype, paratype, syntype, neotype, neoallotype, neoparatype and paralectotype. information is taken from card data, and includes changes in nomenclatural status for each species since their original description. two additional lists, one with updated scientific names for the lice (appendix 1) and another with those for the host taxa (appendix 2), are included.
Two new species of Brueelia Kéler, 1936 (Ischnocera, Philopteridae) parasitic on Neotropical trogons (Aves, Trogoniformes)

ZooKeys , 2011, DOI: 10.3897/zookeys.128.1583
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 B. cicchinoi is only 0.3% divergent from previously published COI sequences identified as Brueelia sp. from the Mexican T. melanocephalus Gould, 1936 and T. massena Gould, 1938. We also found B. cicchinoi on T. melanurus, T. collaris and Pharomachrus pavoninus. Thus B. 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.

ZooKeys , 2013, DOI: 10.3897/zookeys.297.5118
Abstract: We describe and illustrate three new species of chewing lice in the genus Philopteroides parasitic on passerines (Order Passeriformes, families Acanthizidae, Rhipiduridae and Petroicidae) from New Zealand. They are: Philopteroides pilgrimi sp. n. from Gerygone igata igata; Ph. fuliginosus sp. n. from Rhipidura fuliginosa placabilis and R. f. fuliginosa; and Ph. macrocephalus sp. n. from Petroica macrocephala macrocephala and P. m. dannefaerdi. The identity of Docophorus lineatus Giebel, 1874 is discussed based on its morphology and host association. We also transfer Tyranniphilopterus beckeri to the genus Philopteroides, and provide a key to identify adults of 12 of the 13 species now included in Philopteroides.
The correct identity of a louse sample (Phthiraptera: Menoponidae) from the roadside hawk, Rupornis magnirostris (Gmelin) (Falconiformes: Accipitridae)
Valim, Michel P.;Palma, Ricardo L.;
Neotropical Entomology , 2007, DOI: 10.1590/S1519-566X2007000100022
Abstract: a report of a louse sample identified as colpocephalum cholibae price & beer by oliveira et al. (2004), from the roadside hawk [rupornis magnirostris (gmelin)] in the state of s?o paulo, brazil, is regarded as a misidentification. a correction to the identity of the lice is given as kurodaia (kurodaia) fulvofasciata (piaget). key morphological differences between the genera colpocephalum and kurodaia are discussed, as well as possible reasons for the misidentification.

Iheringia. Série Zoologia , 2009, DOI: 10.1590/S0073-47212009000300004
Abstract: a collection of chewing lice was studied from the natural history museum of the universidade católica de pelotas, rio grande do sul, brazil. twenty three samples from 16 bird species were examined. included therein was a new species of the genus plegadiphilus bedford, 1939 which is described, illustrated and compared to p. cayennensis emerson & price, 1969. an updated list of chewing lice species recorded from birds of that state is presented.
ácaros de penas e carrapatos (Acari) associados a Turdus albicollis Vieillot (Aves, Muscicapidae) em uma área de Mata Atlantica da Ilha Grande, Rio de Janeiro, Brasil
Storni, Alline;Alves, Maria A. S.;Valim, Michel P.;
Revista Brasileira de Zoologia , 2005, DOI: 10.1590/S0101-81752005000200017
Abstract: parasitism is an important mechanism affecting populations and communities. the purpose of this study was to investigate the ectoparasites fauna living on the body of the white-necked trush, turdus albicollis vieillot, 1818, and to evaluate if the host body mass is affected by these parasites. turdus albicollis were monthly captured at ilha grande, rio de janeiro, from july 1999 to june 2000 in an area of atlantic forest. the birds were individualy marked, weighed and carefully checked to record and quantify the presence of ectoparasites. parasite abundance and location on the bird's body were recorded. in 54 individuals of t. albicollis sampled, two ectoparasite species were found. the prevalence of the feather mite pterodectes turdinus berla, 1959, and the tick amblyomma longirostre koch, 1844 was 72,2% and 27,8%, respectively. the monthly abundance of p. turdinus was related to the dry and wet months, and it was significantly higher in the dry months than in the wet months. there was no significant relationship between hosts body mass (g) and total abundance of feather mites and ticks.

Brazilian Journal of Veterinary Research and Animal Science , 2004, DOI: 10.1590/S1413-95962004000400004
Abstract: in the present study ectoparasites lodger from 28 guinea pigs living in two differents counties of the rio de janeiro state. the guinea pigs were immobilized mechanically for ectoparasite removal. the parasite specimens collected were counted with the aid of a stereoscopic microscope and identified under light microscope. a total of 3,134 mites were removed from seven guinea pigs from country side. from the 21 guinea pigs of the urban area, 1,472 mites were collected, all being the species chirodiscoides caviae. two hundred and sixty three chewing-lice were found on animals from urban enviromment and 567 chewing-lice from those of the rural enviromment, representing three different species: gliricola porcelli, gyropus ovalis and trimenopon hispidum. the values of parasitic abundance and mean intensity of parasitism were very close and the prevalence in these groups was very high. it was concluded that habitat of the guinea pigs influences the parasitic load of the ectoparasites found in the present study.
