Abstract Chigger mites are ectoparasites of terrestrial tetrapods and can cause dermatitis in the host, known as trombiculiasis. In Brazil, there are 73 species of chiggers; however, cats never have recorded as a host in this country. Here, we report the first record of chiggers parasitizing a domestic cat in Brazil; and a new locality for Eutrombicula tinami (Oudemans 1910) in the Rio Grande do Sul state, Brazil. Keywords Chiggers . Ectoparasites . Rio Grande do Sul State . Trombiculiasis
Introduction According to Zhang et al. (2011), chiggers belong to the families Trombiculidae s.s. Ewing, 1944, Leeuwenhoekiidae Womersley, 1944, and Walchiidae Ewing, 1946 sensu Wen, 1999 (Acari: Trombidiformes), with approximately 3700 described species. Of these, 73 species have been recorded in Brazil (Bassini-Silva et al. 2018; Jacinavicius et al. 2018a, b, 2019, 2020). The larvae of chiggers are ectoparasites of terrestrial tetrapods and, during the feeding, can cause severe skin reactions in their hosts, known as trombiculiasis (Santibáñez et al. 2015). In Brazil, there are few records about people and domesticated animals that had access to the forest and were accidentally Section Editor: Boris R. Krasnov * F. C. Jacinavicius [email protected] 1

bitten by chiggers (Faccini et al. 2017, Sampaio et al. 2020, Bassini-Silva et al. 2019). Some chigger species are known to have low specificity; Eutrombicula tinami (Oudemans, 1910) is one of them. Until now, this species was recorded parasitizing birds (Columbiformes, Cuculiformes, Passeriformes, and Tinamiformes) and mammals (Carnivora, Didelphimorphia, Lagomorpha, and Rodentia), including humans (Oudemans 1910; Jacinavicius et al. 2018a, b; Bassini-Silva et al. 2019). In this study, we first report trombiculiasis in a domestic cat, Felis catus (Linnaeus, 1758) (Carnivora: Felidae) in the state of Rio Grande do Sul, south Brazil.
Case report We examined 12 chigger larvae fixed in ethyl alcohol P.A 100% from a domestic cat, Felis catus, collected in 16-I2020. The sample was slide-mounted with Hoyer’s medium according to Walter and Krantz (2009). Right after, the material was deposited in the Acari
