Tenuipalpidae
Flat mites, False spider mites
Tenuipalpidae, commonly known as flat or false , are a of mites in the Trombidiformes. They are closely related to spider mites () but are distinguished by their dorsoventrally flattened bodies and reduced mobility. Members are typically reddish in color and slow-moving. Several are significant agricultural pests, including Raoiella indica, Brevipalpus phoenicis, B. californicus, B. obovatus, and B. lewisi.
