Background Amblyomma is the second most diversified genus of Ixodidae that is distributed across the Indomalayan, Afrotropical, Australasian (IAA), Nearctic, and Neotropical biogeographic ecoregions, reaching in the Neotropic its higher diversity. There have been hints in previously published phylogenetic trees from mitochondrial (mt) genome, nuclear rRNA, from combinations of both and morphology that the Australasian Amblyomma or the Australasian Amblyomma plus the Amblyomma species from the southern cone of South America, might be the sister-group to the Amblyomma of the rest of the world. However, a stable phylogenetic framework of Amblyommafor a better understanding of the biogeographic patterns underpinning its diversification is lacking. Methods We used genomic techniques to sequence complete and nearly complete mt genomes –ca. 15 kbp– as well as the ribosomal operons –ca. 8 kbp– for 17 Amblyomma ticks in order to study the phylogeny and biogeographic pattern of the genus Amblyomma, with particular emphasis on the Neotropical region. The new genomic information generated here together with genomic information available of 43 ticks (22 other Amblyommaspecies and 21 other hard ticks –as outgroup–) were used to perform probabilistic methods of phylogenetic and biogeographic inferences and time-tree estimation using biogeographic dates. Results In the present paper, we present the strongest evidence yet that Australasian Amblyomma may indeed be the sister group to the Amblyomma of the rest of the world (species that occur mainly in the Neotropical and Afrotropical zoogeographic regions). Our results showed that all Amblyomma subgenera included, but Walkeriana and Amblyomma, are not monophyletic, as in the cases of Cernyomma, Anastosiella, Xiphiastor, Adenopleura, Aponomma, and Dermiomma. Likewise, our best biogeographic scenario supports the origin of Amblyomma and its posterior diversification in the southern hemisphere at 47.8 and 36.8 Mya, respectively. This diversification could be associated with the end of the connection of Australasia and Neotropical ecoregions by the Antarctic land bridge. Also, the biogeographic analyses let us see the colonization patterns of some neotropical Amblyomma species to the Nearctic. Conclusions We found strong evidence that the main theatre of diversification of Amblyomma was the southern hemisphere, potentially driven by the Antarctic Bridge's intermittent connection in the late Eocene. In addition, the subgeneric classification of Amblyomma lacks evolutionary support. Future studies using denser taxonomic sampling may take us to new findings on the phylogenetic relationships and biogeographic history of Amblyommagenus.

“…The tick fauna of the country is by now composed of 78 species, 53 Ixodidae and 25 Argasidae. Amblyomma remains as the richest, with 34 valid species [59]. The original tick fauna was modified by the introduction of exotic species, outstandingly R. microplus and two species of the Rhipicephalus sanguineus complex [60][61][62].…”

In this comprehensive review study, we addressed the challenge posed by ticks and tick-borne diseases (TBDs) with growing incidence affecting human and animal health worldwide. Data and perspectives were collected from different countries and regions worldwide, including America, Europe, Africa, Asia, and Oceania. The results updated the current situation with ticks and TBD and how it is perceived by society with information bias and gaps. The study reinforces the importance of multidisciplinary and international collaborations to advance in the surveillance, communication and proposed future directions to address these challenges.

“…Among ixodid ticks, the Amblyomma genus stands out with a wide range of species (~136), of which 68 occur in the Neotropical Region ( Guglielmone et al, 2021 ; Soares et al, 2023 ). In Brazil, a total of 34 Amblyomma species have been reported, including two recently described species ( Amblyomma romarioi and Amblyomma monteiroae ) ( Martins et al, 2019 ; Dantas-Torres et al, 2019 ; Fuverki et al, 2021 ; Soares et al, 2023 ; Labruna et al, 2023 ).…”

The Amblyomma genus (Arachnida: Ixodidae) is widely distributed in South America, with 34 species occurring in Brazil. Amblyomma nodosum Neumann 1889 is a species that predominantly feeds on Passeriformes during immature stages (larvae and nymphs) and anteaters (Myrmecophagidae) during adult stages. The aim of the present study is to report, for the first time, an unusual case of parasitism by adults of A. nodosum on a yellow cururu toad (Rhinella icterica) captured in the city of Nossa Senhora da Glória, Sergipe state (Northeastern Brazil) in the Caatinga biome, and also investigate the presence of DNA of Rickettsia in the collected material. DNA was extracted from all specimens collected (N=8) and subjected to PCR assays based on the tick 16S rRNA endogenous gene and gltA gene for Rickettsia sp. All samples (8/8; 100%) were positive for the 16S rRNA endogenous gene and two amplicons (obtained from one male and one female) were purified and sequenced. The BLASTn analysis of the sequences revealed a high degree of similarity (95-100%) with A. nodosum sequences previously deposited on GenBank, while the phylogenetic analysis clustered the sequences obtained in the same clade as A. nodosum sequences from Brazil.
