Interpretive Summary: There are thousands species of chiggers in the world and all are parasites that feed on vertebrates including the man. This is a redescription from Brazil of a known species of chigger in the genus Eutrombicula. It will help to recognize the parasite species associated with birds and mammals. These results are important to public health officials, animal protection officers, extension workers, agriculture scientists, entomologists and farmers.

Technical Abstract: Chiggers are parasites of primarily terrestrial vertebrates and can cause severe skin irritiation in the host, known as trombiculiasis. The genus Eutrombicula with ca. 80 species worldwide with some species implicated in trombiculiasis. Six species of Eutrombicula are recorded from Brazil, and only two reported biting humans. In this study, we are improving the taxonomic details of the species Eutrombicula tinami (Oudemans), with new records of localities and host associationss, including biting humans encounter records in Brazil.
