Reviving knowledge: A 70-year gap in the host-parasite relationship between Trichodectes galictidis (Ischnocera: Trichodectidae) and Galictis cuja (Molina, 1782) (Carnivora: Mustelidae).

Galictis cuja is one of the least known mustelids in South America, with its frequency and distribution poorly documented across the Neotropical region from Mexico to Brazil. In February 2024, a female was rescued by fishermen on Porto Beach in Imbituba, Santa Catarina. A clinical examination revealed ectoparasites on the animal, identified as Trichodectes galictidis, a louse species not detected in these animals for over 70 years.

First record of Ixodes uriae White, 1852 (Parasitiformes: Ixodidae) on the great shearwater (Procellariiformes: Procellariidae) in Southern Brazil: a step toward understanding tick-host interactions.

The Great Shearwater, Ardenna gravis, is the largest and most abundant species of procellarid seabirds in the South Atlantic. A specimen of this shearwater was found dead and parasitized by a hard tick on Cima Beach, Santa Catarina State, southern Brazil. Morphological and molecular analyses confirmed the tick's identity as Ixodes uriae.
