New Host Records

This study provides an update on the ectoparasites (ticks and leeches) associated with Rhinoclemmys annulata and provides new accounts on the ectoparasites associated with R. nasuta, R. melanosterna andKinosternon leucostomum from the Pacific coast of Colombia. The presence ofAmblyomma sabanerae on R. nasuta and R. melanosterna provided two new host records for the tick species. Also, the documentation ofA. sabanerae from the Department of Valle del Cauca represents a new department record for the species in Colombia. Placobdella ringueleti was identified fromR. nasuta and K. leucostomum, which represents a new host record for the leech species, as well as a significant extension of the known range.

New Host Records

Abstract The objective of this work was to evaluate the diversity of ticks associated with free-living animals and to investigate new host records for ticks. Ticks were collected from animals rescued during the flood of the Jamari River in the municipality of Ariquemes, state of Rondônia, North Region of Brazil. A total of 39 animals were captured, out of which 10 were amphibians, 19 were reptiles and 10 were mammals. A total of 127 ticks of the Amblyomma genus were collected from these animals, distributed among seven species: Amblyomma dissimile, Amblyomma geayi, Amblyomma humerale , Amblyomma longirostre, Amblyomma nodosum , Amblyomma rotundatum and Amblyomma varium. In addition, one specimen of Rhipicephalus (Boophilus) microplus was collected. Among these specimens, 85 were adults and 42 were nymphs, with A. rotundatum being the most prevalent species. An Amblyomma spp. larvae was also collected from a lizard (Uranoscodon superciliosus), and one Amblyomma calcaratum and one Amblyomma dubitatum were recovered from the environment, thus totaling 130 ticks. Among the Ixodidae collected from different hosts, we provide the first report for the species A. rotundatum parasitizing Rhinella major, U. superciliosus, Leptophis ahaetulla, Chironius multiventris, and Mastigodryas boddaerti, as well as of A. humerale parasitizing U. superciliosus, A. geayi parasitizing Choloepus didactylus, and Rhipicephalus (B.) microplus parasitizing Alouatta puruensis.

Tachyglossus Aculeatus

A nationwide survey was conducted for ticks (Ixodidae) removed from echidnas, Tachyglossus aculeatus (Shaw, 1792), that had been previously collected between 1928 and 2013, and archived within Australian national (Australian National Insect Collection, Australian Capital Territory) and state (Queensland, South Australia, Victoria, and Western Australia) natural history collections. A total of 850 ticks from 89 T. aculeatus hosts were morphologically identified to determine instar, sex and species. Seven larvae, 349 nymphs and 494 adults were identified; 235 were female and 259 were male. The most common tick species was Bothriocroton concolor (Neumann, 1899) (89.2%). In addition, ticks previously recorded from T. aculeatus were identified, including Amblyomma australiense Neumann, 1905 (1.8%), Amblyomma echidnae Roberts, 1953 (0.1%), Bothriocroton hydrosauri (Denny, 1843) (1.4%), Bothriocroton tachyglossi (Roberts, 1953) (1.5%) and Ixodes tasmani Neumann, 1899 (1.2%). For the first time, 22 Amblyomma fimbriatum Koch, 1844 (2.6%) and 19 Amblyomma triguttatum Koch, 1844 (2.2%) ticks were recorded from T. aculeatus. This is the first survey to utilise archived Australian tick collections for the purpose of acquiring new data on tick species that parasitise T. aculeatus.

1. The results of a survey of 194 Peruvian and Colombian primates for filarial infections are presented. Nine genera and 14 species of marmosets and monkeys are represented in the survey. A blood film survey revealed microfilariae in 82, of 42% of the animals. Adult worms were recovered from 21 of 61 dissected animals. The 209 adult worms belong to four species: Dipetalonema gracile, Dipetalonema caudispina, Tetrapetalonema marmosetae, and Tetrapetalonema tamarinae, a new species.2. New host records for Dipetalonema gracile are: Tamarinus nigricollis, Cebus albifrons, and Saimiri boliviensis. Saimiri boliviensis is a new host for Dipetalonema caudispina. New hosts for Tetrapetalonema marmosetae are: Oedipomidas oedipus, Saimiri sciurea, S. boliviensis, and Ateles paniscus.3. The adult worms and microfilaria of a new species of filarial worm, Teirapetalonema tamarinae, are described from a Peruvian tamarin marmoset, Tamarinus nigricollis.

Given the substantial lacunas in the understanding of the occurrence and distribution of bat species in the eastern portion of the Brazilian state of Mato Grosso (Araguaia basin), this study presents an inventory of the species known to occur in the region, highlighting the areas sampled adequately and the species known to occur in conservation units. Georeferenced records of the occurrence of bat species in the region were obtained from published studies, scientific collections, through either the SpeciesLink network or directly from the curator, as well as the capture of specimens by our research group between 2008 and 2013. A 0.5° x 0.5° (latitude/longitude) grid was added to the map of the region for the quantification of the bat species richness of each grid cell. A total of 63 chiropteran species were recorded for the study area. Only 10 of the 30 grid cells had records of bats, and just three contained more than 20 species, and were considered to be sampled adequately on a minimal level. Bat species have been recorded in three conservation units, two state and one municipal. The number of species recorded represents 82.7% of the total of chiropterans known to occur in Mato Grosso, although 12 species were recorded in the state for the first time, reinforcing the paucity of data available on the distribution of bats in the region. The high bat species richness recorded in the present study reinforces the importance of eastern Mato Grosso, a transition zone between the Amazon forest and the Cerrado savanna of central Brazil, for the conservation of Neotropical chiropterans.

Abstract— During a taxonomic and phylogenetic study of Xylopia from the Amazon River basin, South America, we examined collections from the Brazilian states of Amazonas, Mato Grosso, Pará, Rondônia, and Tocantins that resembled Xylopia nitida by some characteristics of the leaves, but differed consistently from the latter in a number of floral and fruit characters. On the basis of these specimens we describe here a new species, Xylopia maasiana. The new species is a small to medium-sized tree encountered mostly in riparian habitats across the southern Brazilian Amazon and in some transition areas between the Amazon forest and cerrado biomes in Central Brazil. In addition to the detailed description, we include a preliminary assessment of conservation status, taxonomic comments, illustrations, a distribution map of the new species, and comparison with X. nitida.

New Host Records

New larval hosts and locality data of an enigmatic tick, Nuttalliella namaqua Bedford, 1931 (Acari: Nuttalliellidae) are recorded. Most of the discovered larvae were found on various species of murid rodents (Rodentia: Muridae), while few larvae were collected on a petromurid rodent (Rodentia: Petromuridae), canid (Carnivora: Canidae), hares (Lagomorpha: Leporidae) and elephant shrew (Macroscelidea: Macroscelididae). Eight species of hosts are new host records for larvae of N. namaqua. This tick species is recorded for the first time from Botswana and Mozambique as well as from new localities in Namibia and South Africa.

Hoplosternum Littorale

This study reports the infection of fishes byAustrodiplostomum compactum metacercariae in the Chavantes reservoir, medium Paranapanema River, municipality of Ipaussu, São Paulo State, Brazil. Twenty-three fish species were analysed, and 13 were infected with A. compactum metacercariae (56.5%) in their eyes. The following six fish species are new hosts for this metacercaria:Crenicichla haroldoi (1/1), Eigenmannia trilineata (11/6), Hoplosternum littorale(11/1), Iheringichthys labrosus (17/2),Leporinus amblyrhynchus (11/1), and Piaractus mesopotamicus (3/1). These new species increase the number of Brazilian fish species infected with this parasite to 36. Based on these findings, we hypothesise that the metacercariae larval stage of the parasite has a low specificity for the second intermediate host (fish). The majority of fish species infected in Brazil belong to the Loricariidae and Cichlidae families. For the fish species with higher mean abundances in Brazil, six are non-native species, and currently, Plagioscion squamosissimus has the highest mean abundance. The majority of fish species infected with A. compactum in Brazil are concentrated in the Paraná basin, although this may be related to the distribution of researchers.

AbstractNinety-five specimens from 13 species of lizard collected during a herpetofaunal monitoring programme of the Faxinal II power plant, municipality of Aripuanã, state of Mato Grosso, Brazil (southern Amazon region) were examined for helminths. A total of 21 helminth species (16 Nematoda, 1 Cestoda and 4 Trematoda) were recovered, with an overall prevalence of 67.37%. Seventeen new host records and seven new locality records are reported. A low number of specialists and core helminth species were found. Lizard body size was positively correlated with both the total number of helminth species and individuals. Active foragers exhibited higher helminth diversity. However, sit-and-wait foragers, especially Plica plica, had similar diversity values as active foragers and harboured more helminth species. The degree of similarity in helminth fauna was higher among closely related host species.
