Predicting the northward expansion of tropical lineage Rhipicephalus sanguineus sensu lato ticks in the United States and its implications for medical and veterinary health
Pascoe, Emily L.; Nava, Santiago; Labruna, Marcelo B.; Paddock, Christopher D.; Levin, Michael L.; Marcantonio, Matteo; Foley, Janet E. (Plos One, 2022-08)The tropical lineage within the Rhipicephalus sanguineus species complex is cause for growing concern in the U.S. based on its prominent role in creating and perpetuating multiple recently identified outbreaks of Rocky ... -
Reassessment of the taxonomic status of Amblyomma cajennense (Fabricius, 1787) with the description of three new species, Amblyomma tonelliae n. sp., Amblyomma interandinum n. sp. and Amblyomma patinoi n. sp., and reinstatement of Amblyomma mixtum Koch, 1844, and Amblyomma sculptum Berlese, 1888 (Ixodida: Ixodidae)
Nava, Santiago; Beati, Lorenza; Labruna, Marcelo B.; Cáceres, Abraham G.; Mangold, Atilio Jose; Guglielmone, Alberto (2014-04)A reassessment of the taxonomic status of Amblyomma cajennense based on the morphological analyses of ticks from the whole distribution area of the species resulted in the redescription of A. cajennense, the validation of ... -
Rhipicephalus sanguineus (Latreille, 1806): Neotype designation, morphological re-description of all parasitic stages and molecular characterization
Nava, Santiago; Beati, Lorenza; Venzal, José Manuel; Labruna, Marcelo B.; Szabó, Matías P.J.; Petney, Trevor; Saracho Bottero, Maria Noelia; Tarragona, Evelina Luisa; Dantas-Torres, Filipe; Silva, Maria M. Santos; Mangold, Atilio Jose; Guglielmone, Alberto; Estrada-Peña, Agustín (2018-09)The aims of this work were to re-describe all parasitic stages of Rhipicephalus sanguineus sensu stricto, to select and deposit a neotype, and to characterize some of its diagnostic molecular traits. A male of R. sanguineus ... -
Species occurrence of ticks in South America, and interactions with biotic and abiotic traits
Estrada-Peña, Agustín; Nava, Santiago; Tarragona, Evelina Luisa; Bermúdez, Sergio; de la Fuente, José; Domingos, Ana; Labruna, Marcelo B.; Mosqueda, Juan; Merino, Octavio; Szabó, Matías P.J.; Venzal, José Manuel; Guglielmone, Alberto (Springer Nature, 2019-12)The datasets of records of the distribution of ticks and their hosts are invaluable tools to understand the phylogenetic patterns of evolution of ticks and the abiotic traits to which they are associated. Such datasets ... -
Synonymy of Ixodes aragaoi with Ixodes fuscipes, and reinstatement of Ixodes spinosus (Acari: Ixodidae)
Labruna, Marcelo B.; Onofrio, Valeria C.; Barros Battesti, Darci M.; Gianizella, Sergio L.; Venzal, José Manuel; Guglielmone, Alberto (Elsevier, 2020-03)Ixodes fuscipes Koch, 1844, described from Brazil, has been considered a valid species with records from Brazil and Peru. Ixodes spinosus Neumann, 1899, also described from Brazil, has been considered a synonym of I. ... -
Taxonomic key to nymphs of the genus Amblyomma (Acari: Ixodidae) in Argentina, with description and redescription of the nymphal stage of four Amblyomma species
Martins, Thiago F.; Labruna, Marcelo B.; Mangold, Atilio Jose; Cafrune Wierna, María Mercedes; Guglielmone, Alberto; Nava, Santiago (2014-10)In the present study, we provide morphological descriptions of the nymph of Amblyomma parvitarsum, A. tonelliae, and redescriptions of A. argentinae and A. sculptum.
