Abstract Predatory mites belonging to family Phytoseiidae (Acari: Mesostigmata) have received great attention. The subgenus Typhlodromus (Anthoseius) De Leon is one of the largest and complicated group in the family Phytoseiidae. There are 11 species of Typhlodromus (Anthoseius) reported in Taiwan so far and eight of them described by Y.H. Tseng. In addition, all specimens including types are lost after his retirement. The undetailed descriptions and the simple illustrations caused some difficulties in proper identifications of Taiwanese species. In this study, six species previously described from Taiwan that follows T. (A.) changi, T. (A.) gracilentus, T. (A.) lanyuensis, and T. (A.) neocrassus, T. (A.) obesus, T. (A.) tridentiger, are re-discovered. In addition, three species, T. (A.) bambusae, T. (A.) chinensis, and T. (A.) serrulatus are reported for the first time for Taiwanese fauna. We also provided the first description of male T. (A.) bambusae. Detailed descriptions of all species and a revised key to the Taiwanese species of the subgenus Typhlodromus (Anthoseius) are also included.
