Abstract

Eutrombidium carajas sp. nov. (Acari: Microtrombidiidae: Eutrombidiinae) is described and illustrated from larvae ectoparasitic on Phalangopsis sp. (Orthoptera: Grylloidea: Phalangopsidae) from Brazil. Eutrombidium carajas sp. nov. belongs to the species group with large and deeply incised lateral coxala I, and coxalae II and III.
