Two new spider mite species collected in southern France on the tiny broom Genista pulchella are described. The new species, Bryobia (Lyobia) baroni sp. n. and Tenuipalpoides genistearum sp. n are among the smallest known species belonging to the genera Bryobia (Lyobia) and Tenuipalpoides, respectively. In addition, pictures, corrections on body size measurements and additional morphological data of Tenuipalpoides ziziphus are provided.
