Synhimantus (Dispharynx) nasuta (Nematoda: Acuariidae) on the Green-barred Woodpecker Colaptes melanochloros (Aves: Picidae) in Argentina.

Only a very small percentage of the total bird species reported for Argentina has been studied from the parasitic point of view. This places wild birds as the least studied compared to other vertebrates. In light of this, the goal of the present study is to contribute to the knowledge of endoparasites on wild birds of Argentina.

First record of Amblyomma tigrinum (Acari: Ixodidae) on puma (Puma concolor) in Argentina and new associations for carnivores in San Juan province.

In Argentina, it has been recorded to occur in nearly all phytogeographic regions, exhibiting its plasticity to different types of environments. This tick is of medical and veterinary importance because its adult stages have been recorded primarily in mammals, including humans.
