Interpretive Summary: Chiggers are parasitic mites that affect wild and domestic animals including humans. We redescribed three important chigger species for Brazil, including new distribution as well new host associations. The information presented here on chigger biology, distribution and identification is important for people in vet/med research, quarantine and biologists.

Technical Abstract: The genus Perissopalla Brennan and White (Trombidiformes: Trombiculidae) is represented by ten species that parasites small mammals, mainly rodents and bats. Three of the ten species were recorded from Brazil: Perissopalla barticonycteris Brennan, Perissopalla ipeani Brennan and Perissopalla tanycera Brennan. In the present study, we are redescribing these three species based on their types, adding new locality and host-association records for P. ipeani and P. tanycera. In addition, we obtained a partial sequence for the 18S rRNA gene for P. ipeani, first time for this genus.
