Interpretive Summary: Recent surveys of the mite fauna in Brazil have revealed a great number of new species. Flat mites are plant feeding mites of increasing economic significance across the world. We reported for first time a flat mite associated with grasses in South America. As part of the research we redescribed the mite species, discussed its association with the host plant and reported for first time a detailed descriptions of the immature stages. This article would be helpful to research scientists, grass growers, USDA-APHIS and Brazilian scientist working with adventive and invasive mite species.

Technical Abstract: Tenuipalpus panici De Leon was originally described from female specimens collected on Panicum maximum Jacq. (Poaceae) from South of Baranquetas, Puerto Rico. In this paper, we redescribe the female of T. panici based on the holotype and on specimens newly collected in Brazil. It is the first record of the species in South America. Females, nymphs and larvae were collected on Paspalum notatum Flüggé (Poaceae); males were absent. New morphological data for both females and immatures (e.g., dorsal and ventral ornamentation, gnathosomal, idiosomal, leg chaetotaxy, and measurements) and a discussion on the patterns of ontogenetic setal additions for all the immature stages are provided. Tenuipalpus panici is the only species of the genus known with two setae appearing on femur IV in the protonymph and successive stages.
