Northwestern Argentina (NOA) is one of the least studied areas in Argentina with respect to ectoparasites of the order Siphonaptera; previous investigations, until this study, were scarce and specific. The objective of this study was to contribute to the knowledge of the diversity of siphonaptera that parasitize small mammals from the NOA, emphasizing in their systematics and distribution. Specimens of fleas collected in several localities of NOA, and stored in the "Annexes" of the Colección Mamíferos Lillo, Universidad Nacional de Tucuman, Argentina, were studied. Fleas were manually removed from the host pelage, fixed in alcohol 70 % and prepared following conventional techniques for later observation under microscope. For specimen identification, the original descriptions of species and subspecies were reviewed and compared with specimens stored in systematic collections. Nine families, 22 genera, 53 species, and eight subspecies were recorded. A new family, a new genus, and three new species are recorded for the first time in Argentina; five species are new for NOA and nine are new to science. The distribution of 11 species and two subspecies are extended in the NOA, new records are added to different provinces and new flea-hosts associations are reported. The greatest diversity of fleas in the Yungas is the reflection of one of the areas with the highest biodiversity in the Neotropical region, such as the Yungas forests, which also includes mammals, as sigmodontine rodents and bats among them. The similarity analysis among eco-regions showed a major faunistic congruence between the Yungas and the Dry Chaco. The greatest differentiation was given by the High Andes and Puna compared with the other eco-regions, probably because these areas are the least surveyed and with the lowest richness and abundance of small mammal species. From the total of 82 new flea-host associations, 81 belong to sigmodontine rodent hosts and one to a marsupial. diferenciación estuvo dada por los Altos Andes y la Puna con respecto al resto, probablemente porque son dos de las áreas menos muestreadas y con menor riqueza y abundancia de especies de micromamíferos. Del total de 82 nuevas asociaciones sifonáptero-hospedador, 81 poseen como hospedadores a los roedores sigmodontinos, y una asociación está constituida por un marsupial.

“…Conservation is urgently needed for some fleas, their hosts, and ecosystems [158][159][160][161][162][163][164][165] since fleas could play important but poorly understood roles in their communities [166][167][168][169][170]. Therefore, flea surveys would be helpful in every biogeographical realm.…”

This overview of extant Siphonaptera lists 19 families with major hosts and general distribution, estimated numbers of genera, species, and subspecies, with a brief taxonomic and phylogenetic review. With around 10 new species described annually, global flea fauna has an estimated extant 249 genera, 2215 species, and 714 subspecies, mostly mammal parasites but 5% of species are on birds. Host specificity varies from euryxenous (i.e. infesting two or more host orders)(e.g. cat fleas, Ctenocephalides felis felis) to monoxenous (e.g. rabbit fleas, Spilopsyllus cuniculi) . The largest family is the paraphyletic Hystrichopsyllidae, making up a third of all flea species. The largest monophyletic family, Ceratophyllidae (rodent and bird fleas), comprise another 20%, and has dispersed to every continent including Antarctica. Fleas descend from scorpionflies (Mecoptera), possibly snow scorpionflies (Boreidae) or Nannochoristidae, and even giant fossils found from the Mesozoic could be Siphonaptera. Flea diversification shows evidence of taxon cycles: "Relict" families such as helmet fleas (Stephanocircidae) have a disjunct distribution reflecting the breakup of Gondwanaland, 70 million years ago. "Niche specialists" include nest fleas (Anomiopsyllus), bat fleas (Ischnopsyllidae), and burrowing fleas, the chigoes (Tungidae). By contrast, Ceratophyllidae fleas could be considered "great speciators". Cat fleas and several other synanthropic flea species are invasive "supertramps". Although those species are intensively studied, many flea species and their hosts require urgent surveys and conservation.

“…Opossums harbor a great diversity of flea species (Horta et al 2007;Pinto et al 2009;Urdapilleta et al 2019;Bezerra-Santos et al 2020b;Canto-Osorio et al 2020), with some of them being regarded as important vectors of zoonotic pathogens (e.g., Ctenocephalides felis felis, Xenopsylla cheopis, Pulex irritans and Pulex simulans), while others (e.g., Adoratopsylla antiquorum, Polygenis occidentalis and Cediopsylla simplex) presenting unknown vector role as studies on their ecology and epidemiology are scanty (Table 2). Among the pathogens transmitted by fleas reported on Didelphis spp., R. typhi, R. felis and Y. pestis are of major public health concern (Azad et al 1997;Demeure et al 2019;Oliveira et al 2020).…”

Didelphis spp. opossums and their parasites in the Americas: A One Health perspective

Medium sized opossums (Didelphis spp.) are among the most fascinating mammals of the Americas, playing important ecological roles (e.g., dispersal of seeds and control of insect populations) in the environment they inhabit. Nevertheless, as synanthropic animals, they are well adapted to human dwellings, occupying shelters within the cities, peripheral areas, and rural settings. These marsupials can harbor numerous pathogens, which may affect people, pets, and livestock. Among those, some protozoa (e.g., Leishmania infantum, Trypanosoma cruzi, Toxoplasma gondii), helminths (e.g., Ancylostoma caninum, Trichinella spiralis, Alaria marcianae, Paragonimus spp.) and arthropods (e.g., ticks, fleas) present substantial public health and veterinary importance, due to their capacity to cause disease in humans, domestic animals, and wildlife. Here, we reviewed the role played by opossums on the spreading of zoonotic parasites, vectors, and vector-borne pathogens, highlighting the risks of pathogens transmission due to the direct and indirect interaction of humans and domestic animals with Didelphis spp. in the Americas.
