Checklist of Bloodfeeding Mites (Acari: Spinturnicidae) from the Wings of Bats (Mammalia: Chiroptera) in the Manú Biosphere Reserve, Peru

A survey collection of mites of the family Spinturnicidae from Peruvian bats includes 11 species of Periglischrus (acutisternus, gameroi, grandisoma, herrerai, hopkinsi, iheringi, micronycteridis, ojasti, paracutisternus, paravargasi, and ramirezi) and 2 Spinturnix (americanus and bakeri); almost all represent new locality records. This survey collection is available for further study at the following repositories: The Harold W. Manter Laboratory of Parasitology, University of Nebraska–Lincoln; the Field Museum of Natural History, Chicago; and the Laboratório de Espeleobiologia y Acarologia, Universidad Nacional Autónoma de México. When spinturnicid mites are collected to avoid cross-contamination by mites among species of bats, parasitic associations are consistently host specific, with Periglischrus spp. distributed exclusively on phyllostomid bats, and Spinturnix spp. on vespertilionids. Notable disjunctions within the Manú Reserve include an absence of spinturnicids on bats of the genus Carollia (Phyllostomidae), or with Chiroderma villosum (Stenodermatinae). Mites of the family Spinturnicidae are not normally associated with bats of the families Emballonuridae, Molossidae, or Noctilionidae. Resumen En una colección de ácaros de la familia Spinturnicidae en murciélagos peruanos se encontraron 11 especies de Periglischrus (acutisternus, gameroi, grandisoma, herrerai, hopkinsi, iheringi, micronycteridis, ojasti, paracutisternus, paravargasi, y ramirezi) y 2 Spinturnix (americanus y bakeri); la mayoría representan nuevos registros de localidad. Esta colección está disponible para su posterior estudio en las siguientes instituciones: Laboratorio de Parasitología Harold W. Manter, Universidad de Nebraska–Lincoln, Field Museum of Natural History, Chicago, y Laboratorio de Espeleobiología y Acarología, Universidad Nacional Autónoma de México. Si los espinturnicidos se recolectan evitando la contaminación cruzada de los ácaros, entre las especies de murciélagos, las asociaciones parasitarias son consistentemente específicas al hospedador, con Periglischrus spp. distribuido exclusivamente en murciélagos phyllostomidos y Spinturnix spp. en vespertilionidos. Las disyunciones notables dentro de la Reserva de Manu incluyen una ausencia de espinturnicidos en los murciélagos del género Carollia (Phyllostomidae), o con Chiroderma villosum (Stenodermatinae). Los ácaros de la familia Spinturnicidae normalmente no están asociados con murciélagos de las familias Emballonuridae, Molossidae, y Noctilionidae

The Enigmatic Spelaeorhynchidae Oudemans, 1902 (Acari: Mesostigmata) Blood-Feeding Ectoparasites Infesting Neotropical Bats, with Catalog and Notes on a Collection from the Manú Biosphere Reserve in Peru

A survey of ectoparasites associated with bats collected along an elevational transect in the Manú Biosphere Reserve, Peru, includes specimens of two species of an unusual and rarely collected family of parasitic mites, the Spelaeorhynchidae Oudemans, and reveals information on the natural occurrence of these infections. In lowland rainforest (450–1,000 m) along the Rio Alto Madre de Dios, Spelaeorhynchus soaresi Peracchi was recorded exclusively infecting two species of frugivorous Carollia, C. brevicauda and C. perspicillata. At higher elevations in the mountains and cloud forests, Spelaeorhynchus praecursor Neumann exclusively infected two species of nectarivorous Anoura, A. cultrata and A. geoffroyi. The consistency of both altitudinal and host distributional limits between sampling periods suggests that the true focus of infection may be sustained in certain habituated, long-term roosting sites. This valuable spelaeorhynchid survey collection (slides and vials) is available for further study at the following repositories: the Harold W. Manter Laboratory of Parasitology, University of Nebraska–Lincoln, and the Field Museum of Natural History, Chicago

Arthropods infesting small mammals (Insectivora and Rodentia) near Cedar Point Biological Station in southwestern Nebraska

Cedar Point Biological Station (CPBS) is located in the mixed grass prairie of the central Great Plains, at the transition between the subregions known as the “tall grass” and “short grass” prairies. Adding to the habitat diversity, there are wetlands and riparian habitats associated with the North Platte River and the edge of the Sandhills region of north central Nebraska. This concurrence of habitats supports a diverse small mammal community. The purpose of this paper is to assemble all published information on ectoparasites associated with small mammals (Insectivora, Rodentia) of southwestern Nebraska, and to report the results of an intensive survey carried out by students of the Parasitology field course during two summers at CPBS. In 2012 and 2013, 27 species of mammal-associated arthropods were collected, including five species of sucking lice (Anoplura), a chewing louse (Ischnocera), six species of fleas (Siphonaptera), thirteen species of mesostigmatic mites (Laelapidae, Macronyssidae, Macrochelidae), and two species of metastigmatic ticks (Ixodidae). These specimens were brushed from the pelage of 11 species of small mammals that were captured in a variety of habitats around CPBS. The arthropod list includes 17 new records for the State of Nebraska. This collection is housed in the Harold W. Manter Laboratory of Parasitology (HWML), University of Nebraska State Museum, at the University of Nebraska-Lincoln, and serves as a taxonomic base for our continued efforts to establish a long-term catalog of parasites associated with small mammals in southwestern Nebraska

Mammalia, Didelphimorphia, Didelphidae, Glironia venusta Thomas, 1912 and Chironectes minimus (Zimmermann, 1780): distribution extension for eastern Amazonia

We report a new record for the bushy-tailed opossum Glironia venusta Thomas, 1912 and the water opossum Chironectes minimus (Zimmermann, 1780) in the Floresta Nacional de Carajás, municipality of Parauapebas, state of Pará, Brazil (06°03’00” S, 50°15’00” W). This study represents the second record of Glironia venusta, but the first voucher specimen for eastern Brazilian Amazon. For Chironectes minimus, this record extends the range of the species 558 km southeastwards from the closest known locality in Pará

Large and medium-sized mammals of Carajás National Forest, Pará state, Brazil

The Carajás National Forest is located in the Amazonian region, Pará State, Brazil and is part of a mosaic of conservation units comprising over one million hectares. This region has been explored for its mineral reserves, but knowledge of the distribution of animals and plants is lacking. The objective of this paper is to provide a list of the medium and large-sized mammals recorded from the Carajás NF. We used four methods to record mammals: linear transects, camera traps, records of road-killed animals, and opportunistic observations. We recorded 45 species distributed in nine taxonomic orders, eight of them currently on the Brazilian list of threatened species and seven in the IUCN red list. The area has high mammalian diversity and holds 56% of the threatened species known for the State, confirming that the study area is correctly categorized as Extremely High Priority for the conservation of Brazilian biodiversity
